Chapter: 60
Section: 6A
A person who imports or exports an article specified in Schedule 1 to the Regulations except under and in accordance with an import or export licence issued by the Director commits an offence and is liable-
(a) on summary conviction to a fine of $500000 and to imprisonment for 2 years; and
(b) on conviction on indictment to an unlimited fine and to imprisonment for 7 years.
So, if the items that you are going to purchase fall into the prohibited category, it is advisable that you do not import them!
