NSW – possession of up to 15 grams of cannabis in NSW may receive a ‘caution’ from the police. 2 caution limit.
QLD - possession of up to 50 grams of cannabis and you will be offered diversion. This is the only state in which diversion must be offered to a minor cannabis offender – elsewhere, it is up to the police officers whether or not they offer diversion or charge the offender. One diversion limit.
* UPDATE: WA (Western Australia) - WA Police Minister Rob Johnson says anyone caught with more than 10 grams of cannabis will face two years jail or a $2,000 fine. He said those caught with fewer than 10 grams must attend a one-on-one counselling session. Apparently this is to be based on a similar system used in QLD (July 2011)
VIC - possession of no more than 50 grams of cannabis will receive a caution. 2 caution limit.
TAS - possession of up to 50 grams of cannabis can be given a caution up to three times in ten years.
