FAQ About Possessing Marketable Quantities of Unlawfully Imported Border Controlled Drugs or Border Controlled Plants

What is a drug analogue in the context of border-controlled drugs?
A drug analogue is treated as a border-controlled drug where it corresponds to a substance listed in the regulations. Even if a substance is not expressly named, it can fall within the definition if it is considered an analogue of a listed border-controlled drug under the Criminal Code.
The AFP Minister has authority under section 301.13 of the Criminal Code Act 1995 (Cth) to determine that a particular substance or plant is a border-controlled drug or border-controlled plant. This determination operates in addition to substances already listed in regulations.
The offence applies to both border-controlled drugs and border-controlled plants. A border-controlled plant includes a plant listed in the regulations or one determined by the AFP Minister under section 301.13 of the Criminal Code.
The substance must fall within the legal definition of a border-controlled drug or border-controlled plant for the offence to apply. Classification determines whether the Commonwealth importation provisions are engaged and whether section 307.6 can be relied upon.
The offence specifically concerns possession of a substance that has been unlawfully imported into Australia. The connection to importation is central, distinguishing this charge from purely state-based drug possession offences.
