Port Management Act 1995

An authorised officer must produce the officer's identity card for inspection—

before exercising a power under this Part; or

if asked to do so by any person at any time during the exercise of a power under this Part.

Subsection (1) does not apply if—

the authorised officer reasonably believes that the production of the officer's identity card would affect the safety or welfare of any person; or

the request to produce the identity card is made by a person to whom the authorised officer has already produced that identity card on the same day before exercising a power under this Part.

Any action taken or thing done by an authorised officer under this Part is not invalidated by the officer's failure to produce the officer's identity card.
