Woomera,
Followed your tip, Perth office palmed me back to CLARC. I dont think I'll bother calling them.
Compressor Stall,
Your cork screw, etc should be fine as Halls Creek does not have a "screened air service" or sterile area. At this stage only jet services are sceened although all security controlled airports have received training in wand waving to initiate screening at any stage.
As for your work ASIC for private purposes - I always thought of the ASIC as proof you have been background checked only - proof of right to access is a different matter.
Although I can see where the confusion comes from as when you apply for an ASIC you have to give (sometimes lengthy) reasons for your requirement for an ASIC - so it blurs the line a little, doesn't it?
I guess the big question is why are spending any more time in Hells Crack than you absolutely have to?
