Welcome neighbour! Nothing is safe! If the cops really wanted, they could easily find prob 90% of us. Most fairly correctly assume they are not going to spend big bux chasing down us little guys but the potential is always there. If they went to someone like 'ome growns place it would be an expensive day out just to slap him on the wrist. And he would just plant another seed tomorrow. Much the same for most of us. You don't generally see aussie commercial growers on here.
I have been a mamber for a couple of years and I know a few other aussie growers who have been online safely for many years. As Buck said earlier, don't steal power, pay your bills on time and keep it low key, don't show all your mates coz it only takes one slip of the lips!
Good luck mate and welcome again.
