yeh i always found that weird about canberra too ... sadly tho back in the day pre 1999 in SA you were allowed (wait for it) 10 plants for personal use in ur house and it was all sweet ... but due to bikie gangs taking advantage and setting up cash crops around the state that has been since shut down
..... i wish i could just have at least 1 plant for personal use then i'd be all sweet ... but oh well ....
