In all honesty, there's more turbine operators around to piston operators. There's very little GA as we (Oz) know it. I bought a Shorts 360 rating because I was converting an Aus ATPL to a JAR one (I had +500 hours multi crew so it was feasable). It helped me get a job in night freight after I did some time in ops as a night ops assistant.
Operators are looking for what operators look for in Oz. Good skills, can work with others etc. Single pilot time isn't held in a lot of regard here. (sad;ly)
I'd have a rummage around the
pilot's job site
