My info is about 20 years out of date and I no longer fly in Australia.
Questions.
1. Where do you want to get a job? In the city or out in the bush?
2. What's your ultimate goal?
Instructing definitely has benefits but I am not sure how the RAA instructing will cross over/be recognised on a CASA licence.
My first chief pilot said that he pretty much discounted any 4 cylinder flying unless it was to somewhere interesting. Use that flying to go somewhere different, such as Birdsville or Alice Springs. That is, gain some remote area experience and so on.
Probably the best forum for this question is the Dununda forum.
Good luck.
