Drug Premises Offences – Laws & Penalties in Australia

Drug premises offences are among the most serious drug-related crimes in Australia. These laws target people who use, manage, or allow premises (such as a house, warehouse, or commercial property) to be used for illegal drug activities such as manufacture, supply, or consumption.

Whether it’s a clandestine meth lab, a cannabis grow house, or a venue where drug use is encouraged, being linked to drug premises can lead to harsh penalties—including lengthy prison terms, property seizure, and criminal convictions.

This guide covers what constitutes a drug premises offence, how police investigate and lay charges, court procedures, available defences, and the state-by-state legal framework.

What Are Drug Premises Offences?

Drug premises offences involve:

• Allowing or permitting your property to be used for manufacturing, selling, storing, or consuming drugs

• Managing or occupying a place used for drug operations

• Failing to report suspected drug activity (in some states)

• Operating or participating in a drug premises enterprise

These charges can apply even if you did not personally handle any drugs—simply being the landlord, tenant, or occupier who knows and allows it may be enough for a conviction.

How Are Charges Laid by Police?

Police may investigate suspected drug premises through:

• Surveillance and informants

• Search warrants

• Forensic evidence (e.g., lab equipment, hydroponics, drug residue)

• Utility usage patterns (e.g., high water or electricity consumption)

• Admissions or text message evidence

Once evidence is gathered, police may issue a court attendance notice, arrest the suspect, or lay multiple charges (e.g., manufacturing + drug premises).

Court Process for Drug Premises Charges

These offences are typically heard in:

• Local or Magistrates’ Court (for less serious matters)

• District, County, or Supreme Court (for aggravated or commercial operations)

If convicted, courts may impose:

• Imprisonment

• Fines

• Forfeiture of the property

• Control orders or ongoing supervision

Defences to Drug Premises Charges

Available legal defences may include:

• Lack of knowledge – You were unaware the premises were used for drug activity

• Lack of control – You had no legal authority over the premises

• Illegal search or procedural error – Police breached warrant conditions or mishandled evidence

• Tenant liability – You leased the property to someone and didn’t know about drug use

Each case depends heavily on the facts, so early legal advice is critical.
