Drug offences are among the most serious criminal charges in Australia and can lead to heavy penalties, including imprisonment. Whether you’re charged under Commonwealth law or your state or territory’s legislation, the consequences can be life-altering. This guide provides an overview of how drug offences are prosecuted in Australia, what defences may be available, and the penalties across each jurisdiction.
In Australia, drug offences can be prosecuted under Commonwealth law or state/territory law, depending on the nature of the offence.
State or Territory police typically lay charges for possession, trafficking, or cultivation within the state.
The Australian Federal Police (AFP) handles offences involving importation, exportation, or offences that cross state or international borders.
Offenders are usually charged after:
Search warrants
Surveillance operations
Sniffer dog detection
Customs or airport inspections
While drug charges are serious, various legal defences may apply:
Lack of knowledge – The accused was unaware they possessed the drug.
Unlawful search – Evidence was obtained in breach of police powers.
Duress – The act was committed due to threat or coercion.
Lack of intent – Particularly in trafficking or supply charges, where intent must be proven.
Legal advice is essential to assess the best defence in each case.
The Commonwealth focuses on large-scale offences such as:
Importing or exporting border-controlled drugs
Drug trafficking across borders
Possession of precursor chemicals for manufacture
Importing/Exporting commercial quantity – Up to life imprisonment
Importing/Exporting marketable quantity – Up to 25 years’ imprisonment
Attempting to possess imported drugs – Up to 10–25 years, depending on quantity
Relevant legislation:
Criminal Code Act 1995 (Cth), Division 300–307
