(1) A person in the Territory who is a party to an act done in a place outside the Territory that:
(a) is an offence against a law in force in that place; and
(b) if the act had been done in the Territory – would be an offence against this Act,
is to be taken to have committed the offence against this Act and, if found guilty of that offence by virtue of this section, is liable to the same penalty and forfeiture as if the act had been done in the Territory.
(2) Subsection (1) is to be construed so that, if the person has previously been found guilty of the offence against a law in force in the place outside the Territory, a court may not find him or her guilty of the offence against this Act.
