"I'm surprised CASA haven't shut them down yet after the amount of accidents/near misses they've had... "




As opposed to the York operation?
I know which one I'd rather not be at.
I think times and operational methodologies have changed at several DZs. How much any of them pay I don't know, but could be dependant on the capacity of the "employment" such as pilot only or chief pilot or what.
Just an idea for thought.

I think you will find that Skydive the Beach run just about all the WA DZs now. Probably 90% of Aussie DZ's are run or controlled by them.
If you want a job suggest you go talk to them find out what their requirements are.

StB have only the one DZ in WA last I heard, unless calling their temporary DZs at Rockingham and Langley Park qualifies, and if that is so then the other operators also have several DZs where they drop into.

Jurien Bay, Busselton, Pinjarra, Hillman (when they operate) and I'm not sure if there is still one in the Pilbara are all separate.

On the other hand StB seem to be cornering the market on the east coast, but 90% of the market is a tad over stated (although I'm sure they are trying).
Given that most of their operations are turbine I guess that will give a starter as to what would be required to get into it apart from the total hours in command and hours on type etc.
