Is Cannabis Possession a Criminal Offence in South Australia?

Yes, possession of cannabis is illegal in South Australia under the Controlled Substances Act 1984 (SA).

While SA has a decriminalised approach for small amounts of cannabis under an expungable expiation system, larger amounts, repeat offences, or related charges such as intent to sell or supply can lead to criminal charges.

  • Expiation Offences (Minor Possession) – If you are caught with a small amount of cannabis (up to 25g) or one non-hydroponic plant, you may receive an on-the-spot fine instead of a criminal charge.
  • Criminal Charges – If you are found in possession of larger amounts, are a repeat offender, or are suspected of trafficking, you could be charged with a criminal offence.

What Are the Penalties for Cannabis Possession in SA?

The penalties for cannabis possession in South Australia vary depending on the quantity and circumstances of the offence:

Possession TypePenalty
Small Quantity (up to 25g)Maximum $500 fine
25g but less than 100gPossible criminal charges, court summons and good behaviour bond
Over 100g or trafficking offenceMaximum $2,000 fine or up to 2 Years Imprisonment

If your case is expiatable, paying the fine avoids a criminal record. However, failing to pay or challenging the charge in court could lead to a conviction.

What Defences Are Available for Cannabis Possession Charges?

If you are facing cannabis possession charges, our lawyers can assess your case and determine if any of the following defences apply:

  • Lack of Knowledge – You were unaware the cannabis was in your possession.
  • Unlawful Search – Police may have conducted an illegal search without a warrant.
