[1] It is responsible for border protection in the exclusive economic zone of Australia and its 19,650 kilometres of coastline and issues such as illegal fishing and exploitation of natural resources, maritime terrorism and piracy, biosecurity threats, and marine pollution.

Flotillas and radio bases are located from the Skardon River in the Gulf of Carpentaria, down the eastern seaboard to Ceduna in South Australia, including Tasmania and major inland lakes and weirs.
Australian Volunteer Coast Guard resources across Australia include: In 1936 Commander Rupert Long, OBE, RAN, Director of Naval Intelligence raised with retired Captain Maurice Blackwood, DSO, RN the possibility of raising a group of trained yachtsmen as a Naval Auxiliary Service.
Discussions were held with HWG Nobbs and W Giles, both Sydney yachtsmen and a proposal sent to the Australian Commonwealth Naval Board that a Volunteer Coastal Patrol be established under the command of Captain Blackwood.
The Naval Board supported this and on 27 March 1937 the Volunteer Coastal Patrol was established under the command of Captain Blackwood, DSO, RN (rtd) with H.W.G.
During World War II Coastal Patrol members became special constables and guarded commercial wharves, oil installations and bridges.
Post war development saw the Patrol undertake civilian search and rescue operations as their primary role but maintain their original Royal Australian Navy inspired organisation structure, ranks and uniform.
They maintain constant watch in Radio Bases for marine traffic, work with the Water Police in search and rescue as well as crowd control at major maritime events, run education classes in seamanship, navigation, first aid and meteorology for the public as well as providing constant information to Radio Stations and TV stations regarding sea conditions etc.
All members of the Patrol are volunteers with a large proportion of their time devoted to raising funds needed in addition to the government provision.
After the Tampa affair, and the declaration of the War on Terrorism, in 2001 Kim Beazley announced that the Australian Labor Party, if in government, would establish an Australian Coast Guard "responsible for conducting Australia's coastal surveillance and meeting Australia's maritime protection needs, including in relation to illegal immigration, drugs, fisheries, and quarantine-related issues".
Peter Reith criticised Beazley for stating that an Australian Coast Guard both will and will not be an "answer to the question of people smuggling".
