Charged with a Drug Offence in Western Australia?
If you’ve been charged with a drug offence in Western Australia, the consequences can be severe, threatening your freedom, your criminal record, and your future. At Kate King Legal, our experienced criminal defence lawyers in Perth are ready to provide immediate legal advice and a clear strategy to protect your rights.

Types of Drug Offences Under WA Law
Drug offences in Western Australia are primarily governed by the Misuse of Drugs Act 1981 (WA), with the most serious matters also prosecuted under the Criminal Code Act Compilation Act 1913 (WA). Common offences include:
- Possession of a Prohibited Drug (s.6 Misuse of Drugs Act 1981)
- Possession with Intent to Sell or Supply (s.6(1)(a) Misuse of Drugs Act 1981)
- Drug Trafficking (s.6 Misuse of Drugs Act 1981)
- Manufacturing a Prohibited Drug (s.7 Misuse of Drugs Act 1981)
- Cultivating a Prohibited Plant (s.7A Misuse of Drugs Act 1981)
- Possession of Drug Paraphernalia (s.9 Misuse of Drugs Act 1981)
The charge you face will depend on the type of drug involved, the quantity, your alleged role, and any prior criminal history. Our drug offence lawyers will explain exactly where you stand and outline your options from the very first contact.
What Penalties Could You Face?
Penalties for drug offences in WA vary significantly depending on the nature of the charge and the circumstances of your case. At the lower end, simple possession offences may result in a fine or a short period of imprisonment. More serious charges such as drug trafficking, manufacturing or large-scale supply can attract penalties of up to 25 years imprisonment. Aggravating factors such as the quantity of drugs, the involvement of minors, or proximity to a school can increase the severity of the outcome. Your prior criminal history will also be weighed by the court. At Kate King Legal, our lawyers will carefully assess every factor in your matter and work toward the best available result.
Your Defence Options
A drug charge does not automatically result in a conviction. Depending on the circumstances of your case, a number of defences may be available, including challenging the lawfulness of a search or seizure, disputing your knowledge of the drugs, or establishing that any substances were for personal use rather than supply. At Kate King Legal, we take a rigorous, evidence-led approach to every case: scrutinising the prosecution’s evidence, identifying weaknesses in their case, and building the strongest possible defence strategy on your behalf.
