State Emergency Service Act 1989

A power to enter premises, or to take action on premises, may not be exercised unless the person proposing to exercise the power is in possession of an authority and produces the authority if required to do so by the owner or occupier of the premises.

The authority must be a written authority that—

states that it is issued under this Act, and

gives the name of the person to whom it is issued, and

describes the nature of the powers conferred and the source of the powers, and

states the date (if any) on which it expires, and

describes the kind of premises to which the power extends, and

bears the signature of the Commissioner or the senior emergency officer who issued the direction under section 22A.

However, despite subsections (1) and (2), a police officer exercising a power to enter premises, or to take action on premises, must produce his or her warrant card if required to do so by the owner or occupier of the premises in lieu of an authority.
