This Act provides a broad set of enforcement powers for use in , and in relation to, maritime areas. Most of these powers are set out in Part   3.

The powers can be used by maritime officers to give effect to Australian laws and international agreements and decisions.

The following are maritime officers :

  (a )   Customs officers;

  (b)   members of the Australian Defence Force;

  (c)   members of the Australian Federal Police;

  (d)   other persons appointed by the Minister.

An authorisation is necessary to begin the exercise of powers in relation to a vessel, installation, aircraft, protected land area or isolated person. The only exceptions are the exercise of aircraft identification powers and the exercise of powers to ensure the safety of persons.

Once an authorisation is in force, maritime officers can exercise powers for a range of purposes.
