Statements in extrinsic materials cannot be substituted for the statutory text1. They may reveal legislative purpose, but must be subjected to scrutiny and treated with caution.

Introducing the Bill, the A-G said categorically it was the latter. Everything contradicted this, the clear aim having been replication of a Queensland offence4. Fagan J (at [57-58]) found the statement to be ‘anomalous’ and questioned whether it reflected the ‘considered intention’ of either the A-G or parliament.
