read that thread... it has all your legal answers
From what i can gather you are allowed to own and have picks at your home, but not carry them.
Most people say any set will do Australian locks, but i think you are better off getting a slim line set (euro/ japanese set) as some of out locks have restrictive keyways. Everything you can do with a standard set you can do with slims, but not the other way around.
hope that helps...
