My wife is Australian and lives in NSW. Not moving for economic gain, in fact I'll likely end up with a simpler and less materialistic lifestyle, which is fine with me. Skilled tradespeople are still very much in demand and there appears to be a number of jobs available to me. Heading down end of next month to check out these possible jobs. Taking my shop as I might actually open a commercial operation there, or just have a hell of a nice hobby shop and tinker with restoring old engines, etc. Moving it all will be expensive, but probably half the cost of buying replacement machines down there.
And yeah, planning is a challenge. I'm still at the stage where every answer leads to 2 or more additional questions...
