I'm in design drafting - looked at doing engineering, but found the drafting side more interesting. Already had a degree in another field so only needed to do a year at TAFE to get my diploma in engineering.
The pay is WAAAAY more than what you're earning now (I'm in mining) - BUT the industry has gone to shit atm with the credit crunch. No chance of getting work atm, but a good time to at least go and get your qualifications and then be ready to start when this shit blows over.
Cheers
