History of the Royal Australian Navy The history of the Royal Australian Navy can be traced back to 1788 and the colonisation of Australia by the British . During the period until 1859 , vessels of the Royal Navy made frequent trips to the new colonies . In 1859 , the Australia Squadron was formed as a separate squadron and remained in Australia until 1913 . During the period before Federation , each of the six Australian colonies operated their own colonial naval force ; these amalgamated in 1901 as the Commonwealth Naval Forces . The Royal Australian Navy ( RAN ) was established in 1911 , and in 1913 the fleet steamed through Sydney Heads for the first time . The Royal Australian Navy has seen action in every ocean of the world during its short life . The RAN first saw action in World War I , and distinguished itself in three oceans . Between the wars the RANs fortunes shifted with the financial situation of Australia : experiencing great growth during the 1920s , but forced to shrink in the 1930s . Entering World War II the RAN was not in the situation it was in 1914 . During the war the size of the RAN grew to over 300 vessels of virtually all classes . By war ' s end , the RAN was the fifth - largest navy in the world . After World War II the RAN saw action in Korea , Vietnam , and other smaller conflicts . Today the RAN fields a small but modern force , widely regarded as one of the most powerful forces in the Asia Pacific Region . Pre - Federation navies . From the colonisation of Australia in 1788 until 1859 , the blue water defence of Australia was provided by detached units of the Royal Navy ' s East Asia Squadron , based in Sydney . In 1859 , Australia was established as a separate Royal Navy squadron ; this marked the first occasion the Royal Navy ships had been permanently stationed in Australia . The Royal Navy ' s Australia Squadron remained the primary naval force in Australian waters until 1913 , when the Royal Navy ' s Australia Station ceased and responsibility handed over to the Royal Australian Navy and its Sydney based depots , dockyards and structures were gifted to the Australian commonwealth . Before Federation , five of the six self - governing colonies in Australia operated their own Colonial navies . Western Australia did not have a Colonial Naval force . The colonial navies were expanded greatly in the mid - 1880s and usually consisted of gunboats and torpedo - boats for coastal defence of harbours and rivers , and naval brigades to man vessels and forts . In 1856 , Victoria received its own naval vessel , HMCSS " Victoria " , which in 1860 was deployed to assist the New Zealand colonial government during the First Taranaki War . When " Victoria " returned to Australia , the vessel had taken part in several minor actions , with the loss of one crewmember . The deployment of " Victoria " to New Zealand marked the first occasion that an Australian warship had been deployed overseas . In the years leading up to Federation , Colonial Victoria became the most powerful of all the colonial navies . Victoria had since 1870 , as well as HMVS " Nelson " , three small gunboats and five torpedo - boats . NSW had two very small torpedo boats , and the corvette " Wolverine " . After Federation all colonial vessels became part of the Commonwealth Naval Forces . Formation . After the Federation of Australia in 1901 , the Commonwealth Naval Forces was formed on 1 March 1901 by amalgamating the six separate colonial navies . The Commonwealth government , however , paid for the Royal Navy to continue providing blue water defence . A growing number of people , among them Captain William Rooke Creswell , the director of the Commonwealth Naval Forces , demanded an autonomous Australian navy , financed and controlled by Australia . In 1909 Prime Minister Alfred Deakin and Creswell , while attending the Imperial Conference in London , sought the British Government ' s agreement to end the subsidy system and develop an Australian navy . The Admiralty rejected and resented the challenge , but suggested diplomatically that a small fleet of destroyers and submarines would be sufficient . Deakin was not impressed with the Admiralty , and in 1908 invited the United States Great White Fleet to visit Australia . The visit prompted public enthusiasm for a modern navy and led to the order of two 700 - ton s , a purchase that angered the British . The surge in German naval construction in 1909 led the Admiralty to change their position on an Australian navy . For his work , Creswell ' s name lives on as the name of the naval base , , the site of the Royal Australian Naval College at Jervis Bay . The first Australian warship , the destroyer , was launched at Govan in Scotland on Wednesday 9 February 1910 . Sister ship was launched at Dumbarton in Scotland on Saturday 9 April 1910 . Both ships were commissioned into the Royal Navy on 19 September 1910 and sailed for Australia , arriving at Port Phillip on 10 December 1910 . The event was marred by the death of Engineer Lieutenant W . Robertson , RN , who suffered a heart attack outside Port Phillip Heads whilst onboard HMAS " Yarra " , and drowned . On 10 July 1911 , King George V fixed his signature to the approval for the Commonwealth Naval Forces to be renamed the Royal Australian Navy , and for RAN ships to carry the prefix " " His Majesty ' s Australian Ship " " ( HMAS ) . The manpower of the fleet stood at four hundred officers and men and , for the next two years , ships were built for the fledgling navy . On Saturday 4 October 1913 the first Fleet Review of the RAN took place , when the battlecruiser , the cruisers and , the protected cruiser , and the torpedo - boat destroyers " Parramatta " , " Yarra " and , entered Sydney Harbour . On the same day , responsibility for the protection of Australia and surrounding waters was transferred from the Australia Squadron of the Royal Navy to the RAN . The Navy was to operate under the authority of the Australian Commonwealth Naval Board . During the Imperial Conference of 1911 , it was decided that if there was war the ships of the RAN would be transferred to British Admiralty control . Under the " Naval Defence Act " ( 1912 ) the power to make the transfer was conferred in the Governor General . The RAN would become the Australia Squadron of the Royal Navy with all ships and personnel under the direct control of the Admiralty , while the RAN remained responsible for the upkeep of the ships and training . World War I . On 3 August 1914 , as the prospect of war with the German Empire loomed , the Australian Government sent the following message to the Admiralty . At the outbreak of war , the RAN stood at 3 , 800 personnel and consisted of sixteen ships , including the battlecruiser " Australia " , the light cruisers " Sydney " and " Melbourne " , the destroyers " Parramatta " , " Yarra " , and " Warrego " , and the submarines and . The light cruiser and three destroyers were under construction , and a small fleet of auxiliary ships was also being maintained . As a consequence the Royal Australian Navy at the start of the war was a small but formidable force . Australian ships first saw action Asian and Pacific theatre ; assisting in the attack on German New Guinea by the Australian Naval and Military Expeditionary Force ( AN & MEF ) . Germany had colonised the northeastern part of New Guinea and several nearby island groups in 1884 , and the colony was currently used as a wireless radio base , Britain required the wireless installations to be destroyed because they were used by the German East Asia Squadron which threatened merchant shipping in the region . The objectives of the force were the German stations at Yap in the Caroline Islands , Nauru , and Rabaul in New Britain . On 30 August 1914 , the AN & MEF left Sydney under the protection of " Australia " and " Melbourne " for Port Moresby , where the force met the Queensland contingent , aboard the transport HMAHS " Kanowna " . The force then sailed for German New Guinea on 7 September , leaving " Kanowna " behind when her stokers refused to work . " Sydney " and her escorting destroyers met the AN & MEF off the eastern tip of New Guinea . " Melbourne " was detached to destroy the wireless station on Nauru , while on 14 September , " Encounter " bombarded a ridge near Rabaul , while half a battalion advanced towards the town . The only major loss of the campaign was the disappearance of the submarine " AE1 " during a patrol off Rabaul on 14 September 1914 . On 9 November 1914 , the German light cruiser attacked the Allied radio and telegraph station at Direction Island in the Cocos ( Keeling ) Islands . The inhabitants of the island managed to transmit a distress signal , which was received by " Sydney " , only away . " Sydney " arrived within two hours , and was engaged by " Emden " . " Sydney " was the larger , faster and better armed of the two , and eventually overpowered " Emden " , with captain Karl von Müller running the ship aground on North Keeling Island at 11 : 15 am . At first , " Emden " refused to strike its colours and surrender ; " Sydney " fired on the stationary " Emden " until it eventually struck its colours . The Battle of Cocos was the first battle the RAN participated in . On 6 February 1915 , the obsolescent light cruiser joined the East African campaign . On 6 July , she engaged the German cruiser and German shore batteries , during the Battle of Rufiji Delta . " Pioneer " remained off East Africa and took part in many bombardments of German East Africa , including Dar - es - Salaam on 13 June 1916 . " Pioneer " then returned to Australia , to be decommissioned in October 1916 . During the Naval operations in the Dardanelles Campaign the Australian submarine became the first Allied warship to breach the Turkish defences of the Dardanelles . " AE2 " spent five days in the area , was unsuccessfully attacked several times , but was unable to find any large enemy troop transports . On 29 April 1915 , she was damaged in an attack by the Turkish torpedo - boat " Sultan Hisar " in Artaki Bay and was scuttled by her crew . The wreck of " AE2 " remained undiscovered until June 1998 . Ships of the Royal Australian Navy also assisted the Royal Navy in the blockade of the German High Seas Fleet . In February 1915 , HMAS " Australia " joined the British Grand Fleet , and was made flagship of the 2nd Battle Cruiser Squadron . " Australia " was not involved in the Battle of Jutland ; in April , the battlecruiser was damaged in a collision with sister ship , and she did not return to service until June . Three RAN ships were present during the surrender of the German High Seas Fleet ; " Australia " , " Sydney " , and " Melbourne " , with " Australia " leading the port division of the Grand Fleet as it sailed out to meet the Germans . Expansion during the war had been limited , with the RAN growing to include thirty - seven ships and more than 5 , 000 personnel by 1918 . The RAN ' s losses had also been modest , only losing the two submarines " AE1 " and " AE2 " , whilst casualties included 171 fatalities – 108 Australians and 63 officers and men on loan from the Royal Navy , with less than a third the result of enemy action . The 1918 – 19 influenza pandemic . Between April 1918 and May 1919 , the Spanish Flu killed approximately 25 million people worldwide , far more than had been killed in four years of war . A rigorous quarantine policy was implemented in Australia ; although this reduced the immediate impact of the flu , the nation ' s death toll surpassed 11 , 500 . When the pandemic struck in 1918 , the ships of the Royal Australian Navy were dispersed throughout the world . The speed at which the flu spread , coupled with the cramped mess decks and poorly ventilated living spaces on early 20th century warships , created a favorable environment for the disease . The pandemic swept through the British Grand Fleet in 1918 ; the Australian cruisers assigned to the fleet suffered high casualties , with up to 157 casualties in one ship alone . Outbreaks in the Mediterranean fleets were more severe than those in the Atlantic . recorded 183 casualties between November and December 1918 , of those casualties 2 men died of pneumonia . The RAN lost a total of 26 men to the disease ; further loss prevented primarily by the ready availability of professional medical treatment . South Pacific aid mission . The disease arrived in the South Pacific on the cargo vessel , which sailed from Auckland on 30 October 1918 whilst knowingly carrying sick passengers . " Talune " stopped in Fiji , Samoa , Tonga and Nauru : the first outbreaks in these locations occurred within days of the ships visits . The local authorities were generally unprepared for the size of the outbreak , allowing the infection to spread uncontrollably . The German territory of Samoa was the worst affected of the small islands , the New Zealand administration carried out no efforts to lessen the outbreak and rejected offers of assistance from nearby American Samoa . The New Zealand government officially apologised to Samoa in 2002 for their reaction to the outbreak . On 29 November 1918 the military governor of Apia requested assistance from Wellington ; the request was turned down because all doctors were needed in New Zealand . Australia offered the only alternate source of aid . The Commonwealth Naval Board was aware of the worsening situation in the region ; the sloop reported its first case on 11 November 1918 while stationed in Fiji , with half her complement eventually affected . On 20 November 1918 , the Naval Board began forming a joint relief expedition from available military medical personnel . The commanding officer of was then ordered to embark the expedition in Sydney and sail as soon as possible . " Encounter " departed Sydney on 24 November 1918 , ten minutes after completing loading . As a precaution , all 450 members of " Encounter " s crew were doubly inoculated ; the ship had suffered 74 cases earlier in the year at Fremantle and the captain did not want a repeat . " Encounter " arrived in Suva on 30 November and took on half of the available coal and 39 tonnes of water . Spanish flu was rampant in Suva ; Captain Thring implemented a strict quarantine , placed guards on the wharf , and ordered that coaling be carried out by the crew instead of native labour . " Encounter " departed Suva in the evening of the same day and arrived off Apia on 3 December . Within six hours , the medical landing party assigned to Apia and their stores were ashore . " Encounter " then departed for the Tongan capital of Nukualofa , arriving on 5 December . The last of the medical staff and supplies were unloaded , and " Encounter " sailed for Suva on 7 December to re - coal . On arriving in Suva , " Encounter " received orders to return to Sydney , where reached on 17 December and was immediately placed into quarantine . The South Pacific aid mission is regarded as Australia ' s first overseas relief expedition , and set a precedent for future relief missions conducted by the RAN . Between the Wars . Following the end of World War I , the Australian Government believed that an immediate evaluation of the RAN was necessary . Australia had based its naval policy on the Henderson " Recommendations " of 1911 , developed by Sir Reginald Henderson . The government sent an invitation to Admiral John Jellicoe , he arrived in Australia in May 1919 . Jellicoe remained in Australia for three months , before returning to England via New Zealand and Canada . Jellicoe submitted his findings in August 1919 , titled the " Report on the Naval Mission to the Commonwealth " . The report outlined several policies designed to strengthen British naval strength in the Pacific Ocean . The report heavily stressed a close relationship between the RAN and the Royal Navy . This would be achieved by strict adherence to the procedures and administration methods of the Royal Navy . The report also suggested constant officer exchange between the two forces . Jellicoe also called for the creation of a large Far East Imperial Fleet , which would be based in Singapore and include capital ships and aircraft carriers . The creation cost for this fleet was to be divided between Great Britain , Australia and New Zealand : contributing 75 % , 20 % , and 5 % respectively . The suggested makeup of the RAN would include ; one aircraft carrier , two battlecruisers , eight light cruisers , one flotilla leader , twelve destroyers , a destroyer depot ship , eight submarines , one submarine depot ship , and a small number of additional auxiliary ships . The annual cost and depreciation of the fleet was estimated to be £4 , 024 , 600 . Except for implementing closer tier with the Royal Navy , none of Jellicoe ' s major recommendations were carried out . With the end of World War I , the Australian Government began to worry about the threat Japan posed to Australia . Japan had extended its empire to the south , bringing it right to Australia ' s doorstep . Japan had continued to build up its naval force , and had reached the point where it outgunned the Royal Navy in the Pacific . The RAN and the government believed that the possibility of a Japanese invasion was highly likely . In his report , Admiral Jellicoe believed that the threat of a Japanese invasion of Australia would remain as long as the White Australia Policy remained in place . Due to the perceived threat , and bilateral support in Australia for the White Australia Policy , the Australian Government became a vocal supporter of the continuance of the 1902 Anglo - Japanese Alliance . Australia was joined in its support for the alliance by New Zealand but was heavily opposed by Canada , which believed that the alliance had hindered the British Empire ' s relationship with China and the United States . No decision on the alliance was agreed on , and the discussion was shelved pending the outcome of the Washington Naval Treaty . The results of the treaty , which allowed the British to retain naval supremacy in the Pacific Ocean , created a sense of security in Australia . Many Australian saw the Four Powers Pact as replacing the Anglo - Japanese Alliance . This sense of security became known as the " Ten Year Rule " . This led to defence retrenchments in Australia , following the international trend , and a £500 , 000 reduction in expenditure . The Governor General Henry Forster when opening parliament on 22 June 1922 was quoted as saying : Between World War I and World War II , the Royal Australian Navy underwent a severe reduction in ships and manpower . As a result of the Washington Naval Treaty , the flagship HMAS " Australia " was scrapped with her main armaments and sunk outside Sydney Heads in 1924 . In the same year , the RAN began a five - year program of obtaining new ships from Britain : the heavy cruisers and and the seaplane carrier . This purchase was partly paid for by scrapping " Brisbane " , " Melbourne " , " Sydney " , and most of the destroyers . The Great Depression of 1929 led to another reduction of manpower ; although reduced in size , the available posts were easily filled as many men were unemployed and the offered pay was greater than most jobs . The RAN ' s personnel strength fell to 3 , 117 personnel , plus 131 members of the Naval Auxiliary Services . By 1932 , the strength of the Reserves stood at 5 , 446 . In the early 1930s , lack of funds forced the transfer of the Royal Australian Naval College from Jervis Bay to Flinders Naval Depot in Victoria . In 1933 the Australian Government ordered three light cruisers ; HMA Ships , , and ; selling the seaplane carrier " Albatross " to fund " Hobart " . During this time , the RAN also purchased destroyers of the V and W destroyer classes , the ships that would became known as the Scrap Iron Flotilla . With the ever increasing threat of Germany and Japan in the late 1930s , the RAN was not in the position it was at the outbreak of World War I . World War II . Australia declared war on Nazi Germany one hour after the United Kingdom ' s declaration of war on 3 September 1939 . At the onset of war the Royal Australian Navy was relatively modest , even if it was arguably the most combat - ready of the three services . Major units included : Following the call up of reserves in 1939 the permanent forces grew from 5 , 440 to 10 , 259 . During the war the men and vessels of the RAN served in every theatre of operations , from the tropical Pacific to the frigid Russian convoys and grew exponentially . The following table illustrates the growth of the RAN between the outbreak of war on 3 September 1939 and 30 June 1945 : Operations against Italy , Vichy France and Germany . From mid - 1940 , ships of the RAN , at the request of the Admiralty , began to deploy to the Mediterranean Sea to take part in the Battle of the Mediterranean against Nazi Germany and Fascist Italy . In September 1939 , the Admiralty and the Australian Commonwealth Naval Board agreed to deploy the RAN Destroyer Flotilla outside the Australia Station ; the five ships of what was to become known as the Scrap Iron Flotilla arrived at Malta in mid - December . HMAS " Sydney " deployed in May 1940 and was later joined by " Hobart " . When Italy declared war on 10 June 1940 , the Australian warships made up five of the twenty - two Allied destroyers and one of the five modern light cruisers on station in the Mediterranean . The RAN then offered the services of " Australia " to the Admiralty , and was accepted . When " Australia " arrived in the Mediterranean , the RAN had sent nearly the entire combat fleet to the Northern Hemisphere , leaving Australian open to possible attack . The entry of Italy into the war also lead to a far more active role for the few remaining RAN vessels on the Australian Station . Indeed on 12 June 1940 , after a prolonged chase , the Armed Merchant Cruiser ( AMC ) forced the Italian merchant ship " Romolo " ( 9 , 780 tons ) to scuttle south - west of Nauru . On 27 June 1940 , Admiral Cunningham commander of the Mediterranean Fleet ordered the 7th Cruiser Squadron , which included HMAS " Sydney " , to rendezvous with an Egypt - bound convoy near Cape Matapan . The cruiser squadron sighted three Italian destroyers at 18 . 00 on 28 June 1940 and immediately engaged them . Within an hour , the was incapacitated and " Sydney " was signaled to sink her . As " Sydney " approached , " Espero " launched torpedoes , but failed to hit any targets . " Sydney " fired four salvos , scoring ten direct hits on " Espero " . " Sydney " remained at the scene for two hours picking up survivors . Also on 27 June 1940 , the was scuttled south of Crete after being depth - charged by and the British destroyers , , , and . On 29 June 1940 , another Italian submarine , the , was sunk west of Crete by the same ships . On 7 July 1940 , a 25 - ship fleet departed Alexandria , intending to meet a convoy east of Malta . The next day , a submarine sighted an Italian fleet away ; the Allied fleet altered course to intercept . The two fleets sighted each other at 15 . 00 on 9 July 1940 , and a battle that became known as the Battle of Calabria began . Four vessels of the RAN took part in the battle ; HMA Ships " Sydney " , , , and " Voyager " . " Sydney " was the first RAN vessel to engage the enemy , and at 15 . 20 opened fire on an Italian cruiser . When the Italian fleet began to withdraw , the Allied destroyer squadron was ordered forward . " Stuart " , leading the destroyer force , was the first to open fire ; her opening salvo was a direct hit at a range of . Both fleets retired , with the Italians withdrawing under smoke , but Italian aircraft continued to attack Allied ships . " Sydney " , which came under heavy air attack , was believed to have sunk . The fleet arrived back in Alexandria on 13 July . On 17 July 1940 , HMAS " Sydney " and the destroyer were ordered to support a Royal Navy destroyer squadron on a sweep north of the island of Crete . At 07 . 20 on 19 July , the Italian cruisers and , which opened fire seven minutes later . The four British destroyers retreated to the north - east , while " Sydney " and " Havock " , away , began to close in . " Sydney " sighted the cruisers at 08 . 29 , and fired the first shots of the Battle of Cape Spada at a range of . Within minutes , " Sydney " had successfully damaged " Bande Nere " , and when the Italians withdrew to the south , the six Allied ships pursued . At 0848 , with " Bande Nere " hiding behind a smoke screen , " Sydney " shifted her fire to " Bartolomeo Colleoni " , which was disabled by 0933 . The Australian cruiser left to pursue " Bande Nere " , but broke off at 10 . 27 as the Italian warship was out of range , and " Sydney " was dangerously low on ammunition . The only damage to " Sydney " during the battle was caused by a shell at 09 . 21 , which knocked a hole in the forward funnel , and wounded a sailor through splinter damage . On 30 September 1940 , HMAS " Stuart " destroyed the Italian 600 - Serie Adua class submarine " Gondar " , killing two of its crew . Twenty - eight survivors was subsequently rescued by " Stuart " , with a further nineteen picked up by other vessels . On 27 March 1941 , an Allied fleet under Admiral Cunningham was ambushed by an Italian naval force off Cape Matapan , Greece . Three vessels of the RAN took part in the battle ; HMA Ships " Perth " , " Stuart " , and " Vampire " . The victory at Cape Matapan allowed the evacuation of thousands of Allied troops from Crete . The Australians experienced further success on 15 December 1941 when attacked and sank the German submarine off Cape St . Vincent , Portugal . West Africa . On 6 September 1940 , HMAS " Australia " was ordered to sail to Freetown , Sierra Leone to join Operation Menace , the invasion of Vichy French - controlled Dakar in French West Africa . On 19 September , " Australia " and the cruiser sighted three Vichy cruisers heading south and shadowed them . When the French cruiser " Gloire " developed engine trouble , " Australia " escorted her towards Casablanca and returned to the fleet two days later . On 23 September " Australia " came under heavy fire from shore batteries , then drove two Vichy destroyers back into port . " Australia " then engaged and sunk the destroyer " L ' Audacieux " with eight salvos in sixteen minutes . Over the next two days French and Allied forces exchanged fire ; " Australia " was struck twice and lost her Walrus amphibian . " Australia " and the rest of the fleet retired on 25 September the battle became known as the Battle of Dakar . The " Scrap - Iron Flotilla " . The Scrap Iron Flotilla was an Australian destroyer group that operated in the Mediterranean and Pacific during World War II . The name was bestowed upon the group by Nazi Propaganda Minister Joseph Goebbels who described the fleet as a " " consignment of junk " " and " " Australia ’ s Scrap - Iron Flotilla " " . The flotilla consisted of five vessels ; , which acted as flotilla leader , and four V - class destroyers ; , , , . The ships were all built to fight in World War I , and were slow and poorly armed compared to newer ships . The five destroyers — the entirety of the RAN ' s destroyer force — departed Australia in November 1939 destined for Singapore where they carried out anti - submarine exercises with the Royal Navy submarine . On 13 November 1939 , the flotilla left Singapore for the Mediterranean Sea , following a request from the Admiralty for assistance . The Australian destroyer flotilla took part in multiple actions while in the Mediterranean , including the Allied evacuation following the battle of Greece in April 1941 , though the flotilla came to fame in the mission to resupply the besieged city of Tobruk . The resupply routes from Alexandria and Mersa Matruh to Tobruk became known as " " Bomb Alley " " and was subject to constant Axis air attacks . The flotilla , which by this time was in poor condition , managed to make 138 supply runs to Tobruk , carrying in ammunition and stores and taking out wounded soldiers . On 28 May 1941 " Vampire " became the first of the flotilla to leave the Mediterranean . " Vendetta " , the last to leave , sailed in October 1941 . Of the five destroyers , three were lost during the war ; " Waterhen " was sunk in the Mediterranean on 30 June 1941 , " Vampire " was sunk by Japanese aircraft during the Indian Ocean Raid and " Voyager " ran aground at Betano , during the Timor campaign and was abandoned . Red Sea . As well as serving in the Mediterranean Sea , ships of the RAN also served in the Red Sea . In August 1940 , Italian forces invaded British Somaliland . After a fighting withdrawal , the small British garrison was evacuated from Berbera , with assisting in the destruction of the port and its facilities . To aid in the delaying action , " Hobart " sent a 3 - pounder gun ashore , operated by volunteers from the crew . The seamen were captured by the Italians , but were later liberated . Two RAN sloops joined the Red Sea force in 1940 : " Parramatta " on 30 July and " Yarra " in September . In October , " Yarra " engaged and drove off two Italian destroyers attempting to raid a convoy . Although vessels of the RAN served in the Red Sea throughout the war , after 1941 the larger RAN ships were deployed to Australian waters in response to the threat from Japan . Loss of HMAS " Sydney " . On 19 November 1941 , the Australian light cruiser and the German auxiliary cruiser engaged each other in the Indian Ocean , off Western Australia . The two ships sank each other : " Sydney " was lost with all 645 hands , while the majority of the " Kormoran " s crew were rescued and became prisoners of war . The location of both wreaks remained a mystery to many and subject to much controversy until 16 – 17 March 2008 , when both ships were found . North Africa . RAN units continued to serve in the Mediterranean campaign , with , taking part in Operation Torch , the invasion of North Africa . On 28 November 1942 Quiberon assisted in sinking the Italian submarine Dessiè and three days later also took part in the destruction of a four - ship convoy and a destroyer . Sicily 1943 . During early 1943 , eight Australian - designed and built s were transferred to Egypt from the Indian Ocean , in preparation for Operation Husky , the Allied invasion of Sicily . They were part of a 3 , 000 - ship Allied force . The corvettes arrived in the Mediterranean in May and were formed into the 21st and 22nd Minesweeping Flotillas . All eight ships survived the campaign without damage or casualties sustained in action , although experienced a near - miss from a German bomber . When the captain of enquired what damage had been sustained , the response from " Maryborough " read : " no damage except to my underpants " . War with Japan . After the Imperial Japanese Navy ' s attacks on the Allies in December 1941 , the RAN redeployed its larger ships to home waters , to protect the Australian mainland from Japanese attack , while several smaller ships remained in the Mediterranean . From 1940 onwards , there was considerable Axis naval activity in Australian waters first from German commerce raiders and submarines and later by the Imperial Japanese Navy . Initially , RAN ships served as part of the British - Australian component of the American - British - Dutch - Australian Command ( ABDACOM ) naval forces or in the ANZAC Force . ABDACOM was wound up following the fall of the Netherlands East Indies and was succeeded by the South West Pacific Area ( command ) ( SWPA ) . The United States Seventh Fleet was formed at Brisbane on 15 March 1943 , for service in the SWPA . RAN ships in the Pacific generally served at part of Seventh Fleet taskforces . Timor . From February 1942 , the RAN played a critical role in resupplying Australian and Dutch commandos on Timor . " Voyager " was not the only loss during the campaign . On 1 December 1942 , was attacked by thirteen Japanese aircraft while attempting to land Dutch soldiers off Betano , Portuguese Timor . " Armidale " sank with the loss of 40 of her crew and 60 Dutch personnel . During the engagement , Ordinary Seaman Teddy Sheean operated an Oerlikon anti - aircraft gun and was wounded by strafing Japanese planes , he went down with the ship , still strapped into the gun and still shooting at the attacking aircraft . Java Sea . On 28 February 1942 , a joint ABDA naval force met a Japanese invasion force in the Java Sea . The " Leander " - class cruiser and the American heavy cruiser fought in and survived the Battle of the Java Sea . On 1 March 1942 , the " Perth " and " Houston " attempted to move through the Sunda Strait to Tjilatjap however they found their path blocked by the main Japanese invasion fleet from western Java . The Allied ships were engaged by at least three cruisers and several destroyers and in a ferocious night action , known as the Battle of Sunda Strait , both Perth and Houston were torpedoed and sunk . Casualties aboard " Perth " included 350 crew and 3 civilians killed , while 324 survived the sinking and were taken prisoner by the Japanese ( 106 of whom later died in captivity ) . The loss of " Perth " so soon after the sinking of her sister " Sydney " , had a major psychological effect on the Australian people . Japanese losses included a minesweeper and a troop transport sunk by friendly fire , whilst three other transports were damaged and had to be beached . Coral Sea . On 2 May 1942 , two ships of the RAN were part of the Allied force in the Battle of the Coral Sea ; HMA Ships and as part of Task Force 44 . Both ships came under intense air attack , while part of a force guarding the approaches to Port Moresby . The defence of Australian shipping . In late May and early June 1942 , a group of five Imperial Japanese Navy submarines made a series of attacks on Sydney and the nearby port of Newcastle . On the night of 31 May – 1 June , the submarines launched three " Ko - hyoteki " - class midget submarine s against Allied shipping in Sydney Harbour . A torpedo intended for the cruiser exploded under the depot ship , killing 21 . On 8 June , two of the submarines shelled Sydney and Newcastle , with little effect . In response , the RAN instituted convoys between Brisbane and Adelaide . All ships of over 1 , 200 tons and with speeds of less than were required to sail in convoy when travelling between cities on the east coast . The attack on Sydney and Newcastle marked the start of a sustained Japanese submarine campaign against Australia . During 1942 , Japanese submarines sank 17 ships in Australian waters , although none of these ships were sailing as part of a convoy . 16 ships were sunk in Australian waters during 1943 , before the Japanese ended the campaign in July . Five of these ships were sunk while sailing in escorted convoys . The Australian naval authorities gradually dismantled the coastal convoy system between December 1943 and March 1944 . By the end of the war , the RAAF and RAN had escorted over 1 , 100 convoys along the Australian coastline . While the scale of the Japanese naval offensive directed against Australia was small compared to other naval campaigns of the war such as the Battle of the Atlantic , these attacks were " the most comprehensive and widespread series of offensive operations ever conducted by an enemy against Australia " . Although the RAN only sank a single full - sized Japanese submarine in Australian waters ( " I - 124 " in January 1942 ) convoy escorts may have successfully reduced the threat to shipping in Australian waters by making it harder for Japanese submarines to carry out attacks . Whilst escorting convoys between Australia and New Guinea , attacked and sank the Japanese " Kaichu " type submarine off Port Moresby on 24 August 1942 , killing all 42 men aboard . Loss of HMAS " Canberra " . The loss of at the Battle of Savo Island in August 1942 was the largest single ship loss the RAN experienced during World War II . In the early hours of the morning of 9 August 1942 , " Canberra " was severely damaged off Guadalcanal in a surprise attack by a powerful Japanese naval force . " Canberra " was hit by 24 shells in less than two minutes , with 84 of her crew killed , including Captain Frank Getting . Following an order to abandon ship , " Canberra " was sunk the next day by a torpedo from a US destroyer , to prevent it being captured . The loss of " Canberra " , following the losses of " Sydney " and " Perth " , attracted unprecedented international attention and sympathy for the RAN . US President Franklin D . Roosevelt wished to commemorate the loss of " Canberra " and requested that a US heavy cruiser under construction be named " Canberra " . was launched on 19 April 1943 . The British Government approved the transfer of to the RAN as a replacement , and the ship was commissioned as HMAS " Shropshire " on 20 April 1943 . Leyte Gulf & Lingayen Gulf . Between 23 – 25 October 1944 four RAN warships – HMA Ships " Australia " , " Shropshire " , , and – took part in the Battle of Leyte Gulf , one of the largest naval battles in history . In the lead - up , on 21 October , " Australia " became the first Allied ship to be hit by a kamikaze aircraft near Leyte Island . Gunners from " Australia " and " Shropshire " fired at , and reportedly hit , an unidentified Japanese aircraft . The plane then flew away from the ships , before turning and flying into " Australia " , striking the ship ' s superstructure above the bridge , and spewing burning fuel and debris over a large area , before falling into the sea . A bomb carried by the plane failed to explode ; if it had , the ship might have been effectively destroyed . At least 30 crew members died as a result of the attack , including the commanding officer , Captain Emile Dechaineux ; among the wounded was Commodore John Collins , the Australian force commander . " Australia " remained on duty , but on 25 October , was hit again and was forced to retire to the New Hebrides for repairs . " Shropshire " and " Arunta " remained at Leyte and were part of the United States Seventh Fleet Support Force at the Battle of Surigao Strait on 25 October . During this action both ships contributed to the sinking of the Japanese battleship , with " Shropshire " firing thirty - two eight - gun broadsides into the battleship with her 8 - inch guns in a period of 14 minutes . HMAS " Australia " returned to combat at the Battle of Lingayen Gulf in January 1945 . During the battle " Australia " was repeatedly attacked between 5 – 9 January , suffering significant damage which forced it to retire once more . Ships with British fleets 1942 – 45 . In 1940 – 42 , five and two were built in the UK and commissioned into the RAN for service with the British Eastern Fleet : HMA Ships , , , , , , and . These ships were predominantly crewed by RAN personnel , although they were often commanded by British officers and remained the property of the British government . Following the Japanese raid on Ceylon of March – April 1942 , the Eastern Fleet was transferred from its base at Trincomalee , to the other side of the Indian Ocean : Kilindi in Kenya . From there the fleet undertook local patrols , escorted convoys and occasionally despatched ships to operations in the Mediterranean . During Operation Vigorous , a convoy to Malta in June 1942 , " Nestor " was serious damaged in an air raid and slowly sank . On 11 February 1944 the corvettes HMA Ships " Ipswich " and " Launceston " , in conjunction with the Indian sloop " Jumna " , sank the Japanese submarine " Ro - 110 " in the Bay of Bengal after the later had torpedoed a ship in a Calcutta - bound convoy . From late 1944 , " Nepal " , " Norman " and " Quiberon " were transferred , along with many other Eastern Fleet ships , to the new British Pacific Fleet ( BPF ) . Among other operations with the BPF , they took part in the Battle of Okinawa . In late 1945 , following the end of hostilities , the RAN acquired three more Q - class destroyers : , , and . The End of the War 1945 . By the end of World War II , the RAN ' s combat strength numbered 150 ships with an additional 200 auxiliary craft with the service reaching its peak in June 1945 , when it ranks swelled to 39 , 650 personnel . During the six years of war , the RAN lost three cruisers , four destroyers , two sloops , a corvette , and an auxiliary minesweeper to enemy action . Casualties included 1 , 740 personnel from the 19 ships sunk , and another 436 personnel killed aboard other ships or at other posts . By most measures , such losses were heavy for such a small service , representing over half its pre - war strength in ships and one - fifth in men . Against this the RAN destroyed one cruiser , an armed merchant raider , three destroyers or torpedo boats , a minesweeper , many light craft and seven submarines . It also destroyed or captured more than 150 , 000 tons of Axis merchant shipping and shot down more than a hundred aircraft . Although difficult to quantify the RAN also played a role in numerous other successes . Surrender and occupation of Japan . Ten RAN vessels were present at the signing of the Japanese surrender in Tokyo Bay on 2 September 1945 ; HMA Ships , , , , , , , , , and . Following the surrender ceremony , the majority of the RAN vessels left Japanese waters for other duties . As part of the surrender agreement , Japan agreed to an Allied occupation and disarmament . On 17 August 1945 , the Australian Government agreed to provide two cruisers and two destroyers for service with the British Commonwealth Occupation Force ( BCOF ) . A total of 15 RAN ships served with the BCOF , the ships performed a variety of tasks but were mainly employed on the Kyushu Patrol , preventing Korean nationals from illegally entering Japan . The RAN also played a role in the disarmament of Japan , assisting in the scuttling of former Imperial Japanese Navy ships , in one instance took part in the sinking of seven submarines of Kyushu as part of Operation Bottom . When Indian and New Zealand contingents began to withdraw from the BCOF , the operation became a predominantly Australian operation . In 1948 , Kure naval base was turned over to Australia , and became known as . When North Korea invaded South Korea on 25 June 1950 , one RAN ship was on station as part of BCOF . The Australian Government immediately offered for United Nations service . Eventually , all RAN ships in the area were transferred to the command of British Commonwealth Forces Korea ( BCFK ) . Clearing mines from Australian and New Guinean waters was another focus for the RAN in the years after the war . Minesweeping began in December 1945 and was conducted by HMAS " Swan " , eight " Bathurst " - class corvettes and several smaller craft from a base at Cairns . The work was arduous and dangerous , and was sunk with the loss of four men killed and another 25 wounded when she struck a mine off North Queensland on 13 September 1947 . The RAN completed this task in August 1948 after sweeping 1 , 816 mines . Cold War . Following World War II , the RAN reduced its surface fleet but continued to expand in other ways , acquiring two Royal Navy s then under construction ( and ) to build up a Fleet Air Arm . In the 1960s , the RAN began to move away from British - designed ships ; the last major British design used was the Type 12 frigate , which formed the basis of the frigates . When it was decided that the RAN should commission a destroyer armed with guided missiles , the obvious British design was the ; however , the RAN had reservations regarding the gas turbine propulsion , the Seaslug missile system , and the ability to adapt the design to Australian needs . Instead , the Australian government chose the United States - built , steam turbine - powered , armed with the Tartar missile as the basis for its " Perth " class , the first major US warship design chosen for the RAN . By the mid - late 1960s , the RAN was at the zenith of its operational capabilities ; it was capable of dispatching a full carrier battle group in support of major operations by having in service an aircraft carrier ( HMAS " Melbourne " ) , three large area defence destroyers of the , six modern frigates and four s . With the retreat of British forces west of the Suez Canal in the 1960s , the RAN began to take a more defensive role , and in co - operation with the United States , allied though the ANZUS treaty . The RAN saw service in many of the world ' s post war conflicts , including Korea , Vietnam , and the Indonesian Confrontation . Korea . On 27 June 1950 , the United Nations Security Council called on member nations to aid South Korea . On 29 June , Prime Minister Robert Menzies announced that the frigate , stationed in Japan , and the destroyer , in Hong Kong , would be placed under UN command in Korea . On 1 July , one day after President Truman committed American ground forces to Korea , the first Australian operation in Korea took place ; " Shoalhaven " escorted an American ammunition ship from Japan to Pusan . The destroyer was deployed in July 1950 , and provided gunfire support during the X Corps landing at Wonsan in October . In December , " Bataan " and " Warramunga " assisted the mass evacuation of troops and refugees from Hungnam . The aircraft carrier was deployed to Korea between September 1951 and January 1952 — the first carrier owned by a Commonwealth Dominion to see wartime service . During this time , 2 , 366 sorties were flown from " Sydney " , with only fifteen aircraft lost and three pilots killed . Over the course of the Korean War , nine ships of the RAN participated in the naval blockade of North Korea . Malaya . The Malayan Emergency was declared on 18 June 1948 , prompted by a rise in Malayan Communist guerrillas in Malaya ( later Malaysia ) . Australia , as a member of the Southeast Asia Treaty Organization , first deployed two RAAF squadrons to the region in 1950 . In 1955 , the Far East Strategic Reserve was created as a concentration of Commonwealth military forces ( primarily British , New Zealand , and Australian ) in Malaya for the protection of that nation from communist threats . Australia ' s commitment included two destroyers or frigates on station at any time , plus an annual visit by an aircraft carrier , and additional ships as needed . Training for the potentiality of war was the main occurrence for ships deployed to the Strategic Reserve , with RAN personnel gaining experience in working as part of a larger naval organisation . The first ships of the RAN to arrive in the area were the destroyers " Warramunga " and in June 1955 . Between 1955 and 1960 , eleven other ships of the RAN operated with the Strategic Reserve : , , , , , , " Sydney " , , and . Indonesia . In response to the Indonesia n invasion of Borneo and Malaya in 1963 , Australia increased its presence in the region . At the outbreak of hostilities , the RAN frigates and were on duty in the area . As tension mounted , Australia increased its presence by sending " Sydney " , " Vampire " , " Vendetta " , , and to the area . On 19 May 1964 , the 16th Minesweeping Squadron , comprising six s , was also deployed . On 13 December 1964 , the minesweeper was fired upon with automatic weapons by an unlit vessel whilst operating as part of the Singapore Strait patrol . The vessel was overpowered and arrested by " Teal " , following a further small arms engagement that resulted in the deaths of three Indonesian crew members . On 23 February 1965 , " Teal " was again involved in another engagement , she detected an unlit vessel off Cape Rachado . The suspicious vessel was closed on and illuminated , and revealed nine armed men in uniform who surrendered immediately upon challenge . On 13 March 1964 , became the second vessel of the 16th Minesweeping Squadron to see action , when she was fired on by an Indonesian shore battery while patrolling off Raffles Lighthouse . Eleven high - explosive rounds were fired at the ship , some landing within of the vessel , and " Hawk " withdrew from the area at speed . The following morning , " Hawk " intercepted a sampan with five Indonesians on board who were promptly arrested . When Indonesian forces crossed the border into Sebatik Island , Sabah on 28 June 1965 , HMAS " Yarra " was called on to carry out bombardments disrupting the withdrawal of the Indonesians . " Yarra " carried out two more bombardments of the border area on 5 and 10 July . During three runs , " Yarra " fired a total of 70 rounds on the enemy . On 13 August 1966 , an agreement between Indonesia and Malaysia brought an end to the conflict . " Melbourne " - " Voyager " collision . During the night of 10 February 1964 , the worst peacetime disaster in the RAN ' s history occurred when the destroyer was cut in two by the bow of the aircraft carrier , killing 82 of the 293 men on board " Voyager " . " Melbourne " was conducting air group exercises off Jervis Bay with " Voyager " acting as the plane guard destroyer . After a series of manoeuvres to reverse the course of the ships , " Voyager " ended up to starboard of " Melbourne " , and was ordered to resume her position ( behind the carrier and to port ) at 20 . 52 . Instead of turning away from " Melbourne " , " Voyager " unexpectedly turned towards the carrier , and did not alter course until it was too late . At 20 . 56 , " Melbourne " s bow hit the destroyer just behind the bridge , and cut her in half , with the bow sinking quickly . The search for survivors went on through the night ; of the 314 aboard , 14 officers , 67 sailors , and 1 civilian dockyard worker were killed , including Captain Duncan Stevens . Following the collision Prime Minister Menzies ordered a Royal Commission to investigate the event . The Commissioner concluded that the collision was primarily the fault of " Voyager " s bridge crew not maintaining an effective lookout , but also placed blame on " Melbourne " s Captain John Robertson ( who resigned shortly after ) and two other officers for failing to alert " Voyager " or take effective measures to avoid collision . The handing of the Royal Commission was seen as poor , and after a combination of public pressure and claims that Stevens had a drinking problem , a second Royal Commission was announced : the only time two Commissions have been held for the same incident . The second Royal Commission found that Stevens was likely medically unfit for command , that some of the first Commission ' s conclusions were therefore incorrect , and the " Melbourne " officers were not at fault . The two commissions caused great anguish in the hierarchy of the RAN , which was not accustomed to such tight scrutiny , and led to the eventual dismantling of the Naval Board ' s isolation from the civilian world . Vietnam War . Ships of the Royal Australian Navy were stationed on continuous operational service in Vietnam between 1965 and 1972 ; a total 18 ships served in Vietnam waters during the war . During this period , the Navy performed a wide variety of operational tasks at sea , ashore , and in the air . The RAN ' s primary contribution consisted of destroyers , Fleet Air Arm personnel attached to a United States Army helicopter company and No . 9 Squadron RAAF , a Clearance Diving Team , and a logistical support force consisting of transport and escort ships . Other RAN personnel served ashore in medical teams or performed staff duties at the Australian Embassy in Saigon or the 1st Australian Task Force Headquarters at Nui Dat . The RAN did not deploy operationally until 1965 , but in 1962 and made goodwill visits to Saigon . They were followed a year later by similar visits by and . In 1967 , became the first RAN destroyer to be operationally deployed to Vietnam . " Hobart " served three tours in Vietnam from March to September in 1967 , 1968 , and 1970 . During her operations , she fired 10 , 000 rounds at 1 , 000 shore targets and came under fire around 10 times , including on one occasion by a United States F - 4 Phantom . " Hobart " was awarded the United States Navy Unit Commendation in recognition of her service in Vietnam , while sister ship received both the United States Navy Unit Commendation and the Meritorious Unit Commendation . In their five years of service in Vietnam , the four gunline destroyers ; " Perth " , , " Hobart " and steamed over 397 , 000 miles and fired 102 , 546 rounds . The aircraft carrier was converted for troopship duties in the early 1960s , and began her first voyage to Vietnam in May 1965 , transporting the 1st Battalion , Royal Australian Regiment , from Sydney to Vung Tau in southern Vietnam . Sydney became known as the " Vung Tau Ferry " and made 25 voyages to Vietnam : carrying 16 , 094 troops , 5 , 753 deadweight tons ( 5 , 845 t ) of cargo and 2 , 375 vehicles . In 1969 , the aircraft carrier rammed and sank another destroyer . During the night of 2 – 3 June , was escorting the carrier during multinational wargames in the South China Sea . Ordered to the plane guard station , " Evans " crosses the carrier ' s bows and was cut in two , killing 74 United States personnel . A Joint RAN - USN Board of Inquiry was established , which found " Melbourne " s Captain John Stevenson and three officers from " Evans " at fault . Despite being cleared by a RAN court - martial , Stevenson resigned after receiving similar treatment to Robertson in the first collision . HMAS " Melbourne " is believed to be the only warship to sink two friendly vessels in peacetime . In April 1971 , Prime Minister John Gorton announced that Australian forces in Vietnam would be reduced . This led to the withdrawal of the clearance divers in May and the Fleet Air Arm in June . The final RAN destroyer on the gunline , " Brisbane " , returned to Sydney on 15 October 1971 . The Whitlam government withdrew all Australian forces from and stopped military aid to South Vietnam . returned to Sydney on 11 March 1972 and was followed the next day by HMAS " Sydney " . During the 10 years that the RAN was involved in the war , eight officers and sailors were killed , and another 46 were either wounded or suffered other injuries . Cyclone Tracy . During the morning of 25 December 1974 , Tropical Cyclone Tracy struck the city of Darwin , killing 71 people and causing $ 4 billion of damage ( 1998 A $ ) . In response to the cyclone , the RAN embarked upon Operation Navy Help Darwin ; the largest peacetime disaster relief operation in its history , involving 13 ships , 11 aircraft and some 3 , 000 personnel . When Tracy struck Darwin , the RAN had a total of 351 personnel based in the city , along with four s ; the small number of men limited the capability of the RAN to render immediate assistance to the citizens of Darwin . All four patrol boats were damaged in some way : and were able to weather the cyclone with minor damage , but was forced aground , and sank after colliding with Stokes Hill Wharf , killing two personnel . Land - based naval installations were also heavily damaged by the cyclone , Darwin Naval Headquarters was destroyed , as were large sections of the patrol boat base and the married quarters . The oil fuel supply installation and naval communications station at were also damaged . The initial RAN relief which was limited to search and rescue in the area of Darwin Harbour and Melville Island , which was hindered by the lack of reliable communications . As the severity of the disaster was realised , a naval task force was established to render aid to the people of Darwin ; Operation Navy Help Darwin . A general recall was issued to all personnel ; volunteers from shore bases and ships unable to sail were used to replace those who could not return to their ships in time . The first RAN assets arrived in Darwin on 26 December , a HS 748 aircraft carrying blood transfusion equipment and Red Cross workers , followed shortly by another HS 748 carrying Clearance Diving Team 1 ( CDT1 ) . Ships also began departing for Darwin on 26 December : and departed from Brisbane , sailed from Cairns , while ( with Rear Admiral Wells aboard ) , , and left Sydney . The next day , , , , and left Sydney , while and sailed from Brisbane . The last ship , , left Brisbane on 2 January . The first vessels , HMA Ships " Brisbane " and " Flinders " , arrived in Darwin on 31 December . " Flinders " surveyed the approaches to Darwin , ensuring the safety of the taskforce , while " Brisbane " landed working parties and established communications . The entire 13 - ship task force had arrived in Darwin by 13 January 1975 , bringing over 3 , 000 personnel . RAN personnel was primarily assigned to clear the suburbs of Nightcliff , Rapid Creek , Northern Territory , and Casuarina , while aircraft and helicopters were used to move evacuees and supplies , and CDT1 inspected ships in the harbour for damage and cleared several wharves . Vessels of the task force began to depart Darwin as early as 7 January , with HMA Ships " Brisbane " and " Stalwart " the last to depart on 31 January , after command of the relief operation was turned over to the Commandant of the Army ' s 7th Military District . Pacific patrol boat program . Following the introduction of the 1982 United Nations Convention on the Law of the Sea ( UNCLOS ) the exclusive economic zone ( EEZ ) of many coastal nations was increased from 12 to 200 Nmi . The sudden expansion of responsibility dramatically increased the area of ocean requiring surveillance , monitoring and policing by these nations , increasing the strain on existing maritime patrol resources , and highlighting the need for countries without a maritime patrol force to obtain one , especially in the South West Pacific area . In 1979 , the Australian and New Zealand Governments , at the request of Pacific Island nations , sent defence representatives into the South - West Pacific region to assess surveillance and maritime patrol requirements . The governments of a number of the Pacific nations expressed their concern about the need for a suitable naval patrol force to meet their new surveillance requirements . The Australian government responded by creating the Defence Cooperation Project ( DCP ) , to provide suitable patrol vessels , training and infrastructure to island nations in the region . The Pacific Patrol Boat Systems Program Office was created within the Minor War Vessels Branch of the RAN procurement organisation . The tender for the vessels was released in August 1984 , and was awarded to Australian Shipbuilding Industries Pty Ltd ( now Tenix Western Australia ) in September 1985 . The first of ten vessels was to be delivered in early 1987 . The first vessel , HMPNGS " Tarangau " , was officially handed over to the Papua New Guinea Defence Force on 16 May 1987 . Over the course of the project the number of participating countries increased . By the end of the construction phase of the project , a total of 22 boats had been delivered to 12 countries , compared to the original order of 10 boats for 8 countries . In total , the project cost for 22 vessels and associated support was A $ 155 . 25 million . The RAN never operated the ( PPB ) , although the project has given the RAN a number of advantages in the Pacific region . The introduction of self - reliant patrol forces throughout the region has eased the strain on Australia ’ s own maritime patrol force . Cooperation between Australia and its Pacific neighbours has allowed for a greater allocation of RAN patrol boats to protecting Australia ’ s maritime resources , patrolling the Sea Lines of Communication ( SLOC ) , and conducting border protection operations . The PPB ' s have recently undergone a mid life refit which could potentially see them operating in the region until at least 2027 . Two - Ocean Policy . The main role of the Royal Australian Navy in the two decades following the end of Australia ' s involvement in the Vietnam War was supporting Australian diplomatic initiatives . In line with this goal the RAN exercised with the navies of Australia ' s allies and provided support to civil authorities in Australia and the South Pacific . The RAN ' s main military concern from the 1970s was the activities of the Soviet Navy in the Indian Ocean . These concerns lead to increased cooperation with the United States Navy and the development of the RAN ' s main base in Western Australia , . During the late 1970s , the RAN replaced many of its aging ships with modern equivalents . While it planned to purchase the British aircraft carrier to replace " Melbourne " , Britain ' s offer of the carrier was withdrawn after the Falklands War . As a result , " Melbourne " was decommissioned without replacement in 1982 and the Fleet Air Arm retired almost all of its fixed wing aircraft on 30 June 1983 . In 1987 , the Hawke Government ' s Defence White Paper called for the RAN to become a more self - reliant " two - ocean " navy with major fleet bases in New South Wales and Western Australia . The plan called for the expansion of " Stirling " on Garden Island and Jervis Bay to accommodate an expanded RAN combat surface and submarine fleets . The plan originally called for the major combat units and submarines to be split between the two fleet bases , providing similar capabilities on both sides of the continent . The proposed Jervis Bay naval base never became a reality ; Fleet Base East was built up around in Sydney while HMAS " Stirling " is home to half the surface fleet and the entire submarine fleet . The rationale behind the policy included the possibility of savings in fuel and maintenance that would result from Indian Ocean deployments beginning their journey from Western Australia rather than New South Wales . The report also classed the Indian Ocean as an area where contingencies might arise . The new facilities would increase Australia ' s worth to the United States , particularly to do with maintenance of submarines . Expansion at Jervis Bay would allow intensified east coast visits by the United States Pacific Fleet , and its nuclear warship visits would not run into as much opposition as they do in Sydney and Melbourne . The 1987 White Paper was seen by many as an attempt to strengthen Australia ' s relationship with the United States , which had been damaged by New Zealand ' s stance against nuclear weapons in its ports . In line with this policy , the RAN was structured to become more self - reliant and its activities during the late 1980s were focused on operating within Australia ' s local region . The Two Ocean Policy remains in place today and is supported by the current Australian Government and the opposition . The success of the policy is especially evident at HMAS " Stirling " . The base is thriving and its location both in a global and local context gives it an advantage over Fleet Base East . It has been suggested that all eight s be relocated to " Stirling " , this would create an easier training environment for sailors and would lead to significant cost savings . Post Cold - War . The Gulf Wars . Australia ' s contribution to the 1991 Gulf War centered on a Naval Task Group , initially Task Group 627 . 4 , which formed part of the multi - national fleet in the Persian Gulf and Gulf of Oman . In addition , medical teams were deployed aboard a U . S . hospital ship and a naval clearance diving team took part in de - mining Kuwait ' s port facilities at the end of the war . Over the period from 6 September 1990 to 4 September 1991 the RAN deployed a total of six ships to the area : HMA Ships , , , , , and . Clearance Diving Team 3 operated in the theatre from 27 January 1991 to 10 May 1991 . It was involved in mine clearing operations in Kuwait from 5 March to 19 April 1991 . After the end of the first Gulf War the Royal Australian Navy periodically deployed a ship to the Gulf or Red Sea to assist in maintaining sanctions against Iraq . Until the outbreak of the Second Gulf War the Australian naval force in the Persian Gulf continued to enforce the sanctions against Iraq . These operations were conducted by boarding parties from the RAN warships . Upon the outbreak of war , the RAN ' s focus shifted to supporting the coalition land forces and clearing the approaches to Iraqi ports . provided gunfire support to Royal Marines during fighting on the Al - Faw Peninsula and the Clearance Diving Team took part in clearing the approaches to Umm Qasr . Boarding operations continued during the war , and on 20 March , boarding parties from seized an Iraqi ship carrying 86 naval mine s . Since the end of the war the RAN has continuously maintained a frigate in the Persian Gulf to protect Iraq ' s oil infrastructure and participate in counter - smuggling operations . Twelve Australian sailors were deployed to Umm Qasr , Iraq between January and October 2004 to join the multi - national training team working with the Iraqi Coastal Defense Force . The RAN has also assumed command of coalition forces in the Persian Gulf on two occasions ; Combined Task Force 58 in 2005 and Combined Task Force 158 in 2006 . HMAS " Westralia " fire . On 5 May 1998 , a fire broke out onboard while off the Western Australia coast . The fire was caused by the rupture of a flexible fuel line ( one of a number used to replace rigid hoses ) on cylinder number nine , starboard engine . This sprayed diesel fuel onto a hot indicator cock , which ignited a spray fire , resulting in the deaths of four crew . Following the fire , the Australian Government and the RAN began a major investigation known as the " Westralia Board of Inquiry " . The enquiry found that the RAN and the contractor Australian Defence Industries ( ADI ) did not critically examine their course of action and that key personnel in both the RAN and the contractor were insufficiently trained and qualified . The inquiry also found that the hoses were not properly designed and were unfit for the intended purpose . In 2005 , ADI was fined $ 75 , 000 for failing to provide a safe workplace . Seven sailors who were apparently severely traumatised by the fire have also sued ADI and subcontractor Jetrock . In August 2006 , the Australian Government decided to accept liability after it reached settlement with the ADI and Jetrock . The seven sailors stand to receive compensation totalling up to $ 10 million . East Timor . During the Australian - led United Nations peacekeeping mission to East Timor in 1999 known as INTERFET , the RAN deployed a total of 16 ships to the mission : HMA Ships , , , , , , , , , , , , , , and . The RAN played a vital role in transporting troops and providing protection to transports and were vital to the success of INTERFET . The RAN returned to East Timor in 2006 under Operation Astute the United Nations - authorised , Australian - led military deployment to East Timor to quell unrest and return stability during the 2006 East Timor crisis . The Royal Australian Navy deployed the Amphibious Ready Group , including the ships ; , , " Tobruk " ( until approximately 8 June ) , " Balikpapan " , " Tarakan " and " Success " ( until 28 May ) . The RAN also deployed the HMAS " Adelaide " ( until 28 May ) . The Fleet Air Arm contributed one S - 70B - 2 Seahawk helicopter from 816 Squadron RAN ( until 28 May ) and two Sea King helicopters from 817 Squadron RAN . The Royal Australian Navy force committed to Operation Astute is apparently the largest amphibious task force in the Navy ' s history . Solomon Islands . On 24 July 2003 , arrived off Honiara , marking the beginning of Operation Anode , Australia ' s contribution to the Regional Assistance Mission to the Solomon Islands ( RAMSI ) . The deployment of a 2 , 200 strong multinational force followed several years of unrest in the Solomon Islands . Manoora was soon joined by HMA Ships , , and . Following the initial deployment , two vessels were generally kept on station in the area . By the time the RAN deployment ended , 19 Australian warships had taken part . The last ship to leave was , which sailed home in October 2004 . Operation Anode was not the first time units of the RAN had been deployed to the Solomon Islands ; Anode was unique in that the navy ' s primary role was to support and facilitate the work of the Participating Police Force ( PPF ) . Moreover , along with being the first time the RAN had supported a police - led mission , Fiji . On 2 November 2006 , in response to the Fijian military threats to overthrow the Fijian Government , the Australian government began Operation Quickstep by deploying military resources to support Australian citizens in Fiji in the event of a coup d ' état . The contribution from the RAN was the deployment of three vessels ; HMA Ships , , and to international waters south of Fiji . The three vessels were deployed to Fiji to evacuate the estimated 7 , 000 Australian citizens present in Fiji if the need arose . Along with the three vessels a detachment of the Special Air Service Regiment , helicopters from the 171st Aviation Squadron and an evacuation team were also deployed . On 29 November 2006 , an Australian Army S - 70A Black Hawk helicopter operating from " Kanimbla " , and carrying ten Army personnel on board , crashed whilst attempting to land on the ship ' s deck , killing 1 person , injuring 7 more and leaving one missing ( later confirmed dead ) . HMAS " Melville " arrived on task the morning of 15 December 2006 , equipped with a Towed Pinger Locating Drone supplied from the United States Navy set about locating the downed Black Hawk . " Melville " detected the locator beacon during its first pass over the crash site and pinpointed its exact location in subsequent passes . The helicopter is sitting in around 2900 metres of water . The coup took place on 5 December , but was bloodless and almost completely without violence . The evacuation of Australians was deemed unnecessary , and vessels of the task force began arriving back in Australia on 17 December , with " Kanimbla " docking in Townsville , and both " Newcastle " and " Success " returning to Sydney . " Melville " returned to Australia in late December . The RAN has decided to attempt to recover the downed Black Hawk and has identified the United States Navy Supervisor of Salvage ( SUPSALV ) as the preferred organisation . MV " Seahorse Standard " recovered the remains of Trooper Porter on 5 March and the Blackhawk helicopter on 9 March , with the assistance of specialist equipment provided by the SUPSALV team . Trooper Porters body was repatriated on 13 March , escorted by members of the Special Air Service Regiment . " Seahorse Standard " arrived in Australia with the aircraft wreckage at the end of March . The wreckage will become evidence in the Board of Inquiry into the crash . Battle honours . Prior to 1989 , the battle honour system of the Royal Australian Navy ( RAN ) was linked to that of the Royal Navy . The British Ministry of Defence and the Admiralty were responsible for approving and assigning battle honours , although from 1947 , this was done on advice from the RAN Badges , Names and Honours Committee . The only uniquely Australian battle honour during this time was " Vietnam 1965 - 72 " ( and smaller date units thereof ) for deployments to the Vietnam War . Ships of the RAN inherited honours from British ships of the same name , in addition to Australian predecessors . In 1989 , the RAN Chief of Naval Staff , Admiral Michael Hudson approved a decision to have Australian warships only carry battle honours earned by previous Australian vessels . The creation and awarding of battle honours came completely under RAN control . A complete overhaul of the RAN battle honours system was unvelied on 1 March 2010 , to celebrate the navy ' s 109th anniversary of creation . New honours were created for operations during the 1990s and 2000s — the last approved honour prior to this was " Kuwait 1991 " , for Gulf War service — and the service history of previous vessels was updated to include ' due recognition ' of previous actions . Women in the RAN . From 1911 to 1941 women were forbidden from serving in the RAN ; the demands World War II placed on personnel and resources led to a change of policy . On 21 April 1941 , the Australian Naval Board sent a letter authorising the entry of women into the RAN to the Commodore - in - Charge , Sydney . The letter led to the formation of the Women ' s Royal Australian Naval Service ( WRANS ) and the Royal Australian Naval Nursing Service ( RANNS ) . The two separate women ' s services existed until 1984 , when they were incorporated into the permanent force . Today , female members of the RAN have a wide variety of roles open to them ; women serve on submarines , command ships and shore postings and are expected to play an increasingly important role in the future of the RAN . The current navy . The Royal Australian Navy today is a medium sized modern navy in world terms but is one of the strongest navies in the Asia Pacific Region . Today , the combat fleet of the RAN is made up of eight s , four s , fourteen patrol boats of the , and six s . The RAN also comprises an amphibious and supply force to transport the Australian Army and to resupply the combat arm of the navy . The RAN is divided into seven Force Element Group s ( FEGs ) : Surface Combatants , Amphibious Warfare Forces and Afloat Support Force , Naval Aviation , Submarine Force , Mine Warfare and Clearance Diving , Patrol Boat Force and the Hydrographic Force . The FEG ' s were formed to manage the operations of the separate sections of the RAN in a more efficient way . The modern RAN began to form during the late 1970s when the Fraser Government announced the purchase of four s , all to be built in America ; in 1980 they announced an additional two vessels both to be built in Australia . The fifteen Australian - built vessels of the made up Australia ' s patrol boat from 1979 to 2007 ; they have now been replaced by the fourteen s . The is the newest class of Australian submarines , built in Australia for the Royal Australian Navy . They were constructed by the Australian Submarine Corporation in Adelaide , South Australia , and replace the six s in the Australian fleet . The first vessel , , was laid down in 1990 and commissioned in 1996 , with all six vessels of the class in service and based at in Western Australia . The is the current main fleet unit of the Royal Australian Navy ; the class has eight vessels . The lead vessel of the class , , was commissioned in 1996 and the final vessel , , was commissioned on 26 August 2006 . Along with the eight Australian vessels , two " Anzac " s were also constructed for the Royal New Zealand Navy . The " Anzac " class were jointly constructed in New Zealand and Australia with the final fitout in Williamstown , Victoria . The amphibious and supply arm of the RAN is made up of ; one landing platform , one heavy landing ship ( ) , six landing craft , two s , four es , the fleet oiler , and the Dual Stores Replenishment Vessel . The RAN also has six s . The Royal Australian Navy maintains several bases around Australia . Under the RAN ' s Two - Ocean Policy , ( Fleet Base West ) and ( Fleet Base East ) are the primary bases for all major fleet unit of the RAN . The majority of the patrol boat and amphibious forces are located at and , while all Fleet Air Arm squadrons are based at . The future of the RAN . In 2000 , a major white paper was produced by the Australian Government , which set out a program of defence spending that will see significant improvements to the RAN ' s fleet and capabilities . The most significant current project is " SEA 4000 " the procurement of three " Hobart " - class destroyers , which will replace the " Adelaide " class . These ships will be fitted with the AEGIS combat system , and will be based on the Spanish F100 design . The class has a planned in service date of 2013 , with the three units to be named " Hobart " , " Brisbane " , and " Sydney " . In August 2005 the Australian Government passed approval for the acquisition of two s ; these will displace over 20 , 000 tonnes , can carry over 1 , 000 troops , and will potentially be able to operate fixed wing aircraft . The project is expected to cost between A $ 1 . 5 and A $ 2 billion , and be completed by around 2014 . The new ships will be named " Canberra " and " Adelaide " .
