I would have a look at
SEEK - Australia's no. 1 jobs, employment, career and recruitment site or
AllJobs.com.au - Search for Jobs in Australia for a guide to where the jobs are and to try an get an idea of wages.
Real Estate | Homes for Sale | Houses for Sale | MLS Listings | REALTORs | Real Estate Agents - RealEstate.com will give you an idea of property prices in various places too,loads of truck drivers dont work away from home ,i would imagine its more money if you do though,,good luck with everything and if your heading brisbane way and need digs give me a shout,,
