This Part provides for the exercise of maritime powers and powers specified in international agreements and decisions .

An authorisation must be given by an authorising office r before powers can be exercised in relation to a vessel, installation, aircraft, protected land area or isolated person . The only exceptions are:

  (a)   the exercise of aircraft identification powers to identify aircraft ; and

  (b)   the exercise of maritime powers to ensure the safety of a maritime officer or any other person.

Once an authorisation is in force , a maritime officer may exercise powers for the purposes of the author isation, and for other purposes set out in Division   4 .

The exercise of powers in relation to a vessel, installation , aircraft or protected land area extends to persons and things with a connection to the vessel, installation, aircraft or protected land area.

Powers can be exercised in, and in relation to, maritime areas, but their exercise is limited in places outside Australia (see Division   5) .
