I haven't been in the GA scene for a few years now, but with all the majors in Australia and overseas now hiring, I thought the progression would almost be at an all time high.
I'd say high single time is not a disadvantage if you don't expect to jump straight into a twin. Be prepared to spend another year in a single with a company that has good twin progression e.g. Hardy's, Hinterland, Broome Air Services etc.
Chase it and most importantly network as much as possible.
It will happen.
