A biosecurity enforcement officer who needs access to premises may gain that access through adjacent premises if authorised by warrant. A biosecurity officer may also gain access that way if accompanied by a biosecurity enforcement officer who is authorised by warrant to gain access that way.

Special rules apply to consent for biosecurity enforcement officers to enter premises, to ensure the consent is voluntary.

Biosecurity enforcement officers acting under a warrant are also subject to special rules, and have certain powers.

Occupiers of premises entered under a warrant, and their representatives, have rights to observe execution of the warrant and obligations to assist those executing it.
