Australian marine parks are marine protected areas located within Australian waters and are managed by the Australian government. These waters generally extend from three nautical miles off the coast to the outer limit of Australia’s Exclusive Economic Zone at 200 nautical miles while marine protected areas located closer in-shore are the responsibility of the states or the Northern Territory.

Marine protected areas (MPA) are protected areas of the world's seas, oceans, estuaries or in the US, the Great Lakes. These marine areas can come in many forms ranging from wildlife refuges to research facilities. MPAs restrict human activity for a conservation purpose, typically to protect natural or cultural resources. Such marine resources are protected by local, state, territorial, native, regional, national, or international authorities and differ substantially among and between nations. This variation includes different limitations on development, fishing practices, fishing seasons and catch limits, moorings and bans on removing or disrupting marine life. In some situations, MPAs also provide revenue for countries, potentially equal to the income that they would have if they were to grant companies permissions to fish. The value of MPA to mobile species is unknown.
