Ah good on you mate!! It's a bit the same back here, extra courses after completion of your apprenticeship (that are like 8,000 AU) and then plumbing is heavily governed (inspections) only gas is self certified... But I'm happy to just work for someone, especially since it would all be so differant to how we do things here!!
Thanks again J, we had a quick look the other day for places to rent and had a few we liked come up around The Etihad, absolutely no idea what the area itself is like! (I'll definitely have to get a few of you out for a beer!)
