Australia, with 19,650 kilometres of coastline does not have a force purely to defend its coast.
 The duty of patrolling the Australian coastline falls to the Royal Australian Navy, the Australian Border Force Maritime Border Command, and the Police services of the states.
 In addition, there are several private volunteer coast guard organisations, the two largest organisations being the Royal Volunteer Coastal Patrol (established in 1937 as the Volunteer Coastal Patrol) and the Australian Volunteer Coast Guard (established in 1961).
 These volunteer organisations have no law enforcement powers, but are essentially auxiliary Search and Rescue services.
 In July 2009 the three organisations (Royal Volunteer Coastal Patrol, Australian Volunteer Coast Guard and some units of the Volunteer Rescue Association's Marine Branch) united in New South Wales under the government sponsored Marine Rescue NSW.
 The Australian Volunteer Coast Guard remains operational in Victoria, Queensland, Northern Territory, South Australia and Tasmania alongside a number of other Volunteer Marine Rescue agencies.

Admiralty law or maritime law is a distinct body of law that governs maritime questions and offences.
 It is a body of both domestic law governing maritime activities, and private international law governing the relationships between private entities that operate vessels on the oceans.
 It deals with matters including marine commerce, marine navigation, marine salvaging, shipping, sailors, and the transportation of passengers and goods by sea.
 Admiralty law also covers many commercial activities, although land based or occurring wholly on land, that are maritime in character.
The Marine Mammal Protection Act (MMPA) was the first act of the United States Congress to call specifically for an ecosystem approach to wildlife management.
 It was signed into law on October 21, 1972 by President Richard Nixon and took effect 60 days later on December 21, 1972.
 MMPA prohibits the "taking" of marine mammals, and enacts a moratorium on the import, export, and sale of any marine mammal, along with any marine mammal part or product within the United States.
 The Act defines "take" as "the act of hunting, killing, capture, and/or harassment of any marine mammal; or, the attempt at such."
 The MMPA defines harassment as "any act of pursuit, torment or annoyance which has the potential to either: a. injure a marine mammal in the wild, or b. disturb a marine mammal by causing disruption of behavioral patterns, which includes, but is not limited to, migration, breathing, nursing, breeding, feeding, or sheltering."
 The MMPA provides for enforcement of its prohibitions, and for the issuance of regulations to implement its legislative goals.

 It trains people in marine science and its related disciplines, researches on marine, brackish and related environments and their resources, provides assistance to the government on maritime issues, publishes books and journals on marine science, and disseminates technology on marine science to the stakeholders.
The Marine Park and Reserves Unit of Tanzania was formed in 1994 under the Marine Parks and Reserve Act No 29, of 1994.
 Previously all marine life and biodiversity was under the Ministry of Livestock and Fisheries.
 The population along the 1400 km Tanzanian coastline has reached to over 10 million and the increase in number of people who's livelihood depends on the marine resource has also increased.
 The increase in population has caused various threats to the marine life due to over fishing, coral mining and unplanned increase in settlements.
 To protect the marine biodiversity the Government of Tanzania established the Marine Park and Reserves unit in 1994 with Mafia Island Marine Park as the first marine park.
