Situated between the Indian and Pacific oceans, it is the world's largest island country, with more than seventeen thousand islands. At , Indonesia is the world's 14th-largest country in terms of land area and world's 7th-largest country in terms of combined sea and land area. It has an estimated population of over 260 million people and is the world's fourth most populous country, the most populous Austronesian nation, as well as the most populous Muslim-majority country. The world's most populous island of Java contains more than half of the country's population. - The Yarra River is a river in East - Central Victoria , Australia that flows through the city of Melbourne . This article contains explanations and lists of the river 's tributaries and other geographic features . The river flows atop layers of silt that built up within an ancient river valley around 10,000 - 15,000 years ago . The river 's major tributaries are the Plenty River , Merri Creek , Darebin Creek , Diamond Creek , Gardiners Creek , Mullum Mullum Creek and the Moonee Ponds Creek . It hosts a wide range of geographic features including ; bends , rapids , lakes , islands , floodplains , billabongs , wetlands , etc. Most features have been named after translated Woiwurrung phrases or have European , particularly British , origins . - Port Phillip (also commonly referred to as Port Phillip Bay or (locally) just The Bay), is a large bay in southern Victoria, Australia; it is the location of Melbourne. Geographically, the bay covers and the shore stretches roughly . Although it is extremely shallow for its size, most of the bay is navigable. The deepest portion is only , and half the region is shallower than . The volume of the water in the bay is around . - An ocean (the sea of classical antiquity) is a body of saline water that composes much of a planet's hydrosphere. On Earth, an ocean is one of the major conventional divisions of the World Ocean, which covers almost 71% of its surface. These are, in descending order by area, the Pacific, Atlantic, Indian, Southern (Antarctic), and Arctic Oceans. The word "sea" is often used interchangeably with "ocean" in American English but, strictly speaking, a sea is a body of saline water (generally a division of the world ocean) partly or fully enclosed by land. - New Zealand is an island nation in the southwestern Pacific Ocean. The country geographically comprises two main landmassesthat of the North Island, or Te Ika-a-Mui, and the South Island, or Te Waipounamuand numerous smaller islands. New Zealand is situated some east of Australia across the Tasman Sea and roughly south of the Pacific island areas of New Caledonia, Fiji, and Tonga. Because of its remoteness, it was one of the last lands to be settled by humans. During its long period of isolation, New Zealand developed a distinct biodiversity of animal, fungal and plant life. The country's varied topography and its sharp mountain peaks, such as the Southern Alps, owe much to the tectonic uplift of land and volcanic eruptions. New Zealand's capital city is Wellington, while its most populous city is Auckland. - Papua New Guinea (PNG Hiri Motu: "Papua Niu Gini"), officially the Independent State of Papua New Guinea, is an Oceanian country that occupies the eastern half of the island of New Guinea and its offshore islands in Melanesia, a region of the southwestern Pacific Ocean north of Australia. Its capital, located along its southeastern coast, is Port Moresby. The western half of New Guinea forms the Indonesian provinces of Papua and West Papua. - A sea is a large body of salt water that is surrounded in whole or in part by land. More broadly, "the sea" is the interconnected system of Earth's salty, oceanic watersconsidered as one global ocean or as several principal oceanic divisions. The sea moderates Earth's climate and has important roles in the water cycle, carbon cycle, and nitrogen cycle. Although the sea has been traveled and explored since prehistory, the modern scientific study of the seaoceanographydates broadly to the British "Challenger" expedition of the 1870s. The sea is conventionally divided into up to five large oceanic sectionsincluding the International Hydrographic Organization's four named oceans (the Atlantic, Pacific, Indian, and Arctic) and the Southern Ocean; smaller, second-order sections, such as the Mediterranean, are known as "seas". - Australia, officially the Commonwealth of Australia, is a country comprising the mainland of the Australian continent, the island of Tasmania and numerous smaller islands. It is the world's sixth-largest country by total area. The neighbouring countries are Papua New Guinea, Indonesia and East Timor to the north; the Solomon Islands and Vanuatu to the north-east; and New Zealand to the south-east. Australia's capital is Canberra, and its largest urban area is Sydney. - Melbourne is the capital and most populous city of the Australian state of Victoria, and the second-most populous city in Australia. The name "Melbourne" refers to an urban agglomeration spanning which comprises the broader metropolitan area, as well as being the common name for its city centre. The metropolis is located on the large natural bay of Port Phillip and expands into the hinterlands towards the Dandenong and Macedon mountain ranges, Mornington Peninsula and Yarra Valley. Melbourne consists of 31 municipalities. It has a population of 4,529,500 , and its inhabitants are called Melburnians. - The Mornington Peninsula is a peninsula located south-east of Melbourne, Australia. It is surrounded by Port Phillip to the west, Western Port to the east and Bass Strait to the south, and is connected to the mainland in the north. Geographically, the peninsula begins its protrusion from the mainland in the area between Pearcedale and Frankston. The area was originally home to the "Mayone-bulluk" and "Boonwurrung-Balluk" clans and formed part of the Boonwurrung nation's territory prior to European settlement. - The Yarra Valley is the name given to the region surrounding the Yarra River in Victoria, Australia. The river originates approximately 90 kilometres east of the Melbourne central business district and flows towards it and out into Port Phillip Bay. The name Yarra Valley is used in reference to the upper regions surrounding the Yarra River and generally does not encompass the lower regions including the city and suburban areas, where the topography flattens out, or the upper reaches which are in inaccessible bushland. Included in the Yarra Valley is the sub-region of Upper Yarra (or the Upper Yarra Valley) which encompasses the towns of the former Shire of Upper Yarra in the catchment area upstream of and including Woori Yallock. The Yarra Valley is a popular day-trip and tourist area, featuring a range of natural features and agricultural produce, as well as the Lilydale to Warburton Rail Trail. - A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. - Vanuatu (or ; Bislama ), officially the Republic of Vanuatu (Bislama: "Ripablik blong Vanuatu"), is a Pacific island nation located in the South Pacific Ocean. The archipelago, which is of volcanic origin, is some east of northern Australia, northeast of New Caledonia, east of New Guinea, southeast of the Solomon Islands, and west of Fiji.
