A person must not wilfully delay or obstruct a person (including a public authority) who is carrying out any action in compliance with an order or notice under this Part.

for a corporation—$1,000,000 and, for a continuing offence, a further penalty of $120,000 for each day the offence continues, or

for an individual—$250,000 and, for a continuing offence, a further penalty of $60,000 for each day the offence continues.

It is a defence to a prosecution for an offence under this section if the defendant establishes that the delay or obstruction to the person occurred in a situation in which the person was present on the land without the permission of the occupier or contrary to the terms of the occupier’s permission.
