An aider and abettor of a strict liability fisheries offence must have knowledge of all essential facts constituting the offence — for taking undersize abalone, knowledge that the abalone are undersize; for taking more than ten, knowledge that more than ten are being taken.

Mandatory fixed penalties per fish in fisheries regulations are not constitutionally invalid under Ch III of the Constitution.
