so a couple of things on that.
1 it's NSW so DEZZ is still safe.
2, those hourly rates are how much it costs, not earnings. remembering in most cases they need tools, insurance, a vehicle to travel in advertising blah blah blah so the real take home salary is not going to be that high. (not saying they are broke or anything but that is hiding some info)
3. the big issue I see with friends who are trades, is now they are getting past the 40 mark they are looking at what next. it's hard to think of climbing though roofs and things when your late 60s, where as I can comfortably sit on my ass behind a desk to retirement age.
