the one that is subsidised by Aus taxpayers
WRONG. There is no Australian Govt. subsidy - none, and never has been!! If anything, the airline got assistance from Taiwan in the past but not from Australia.
They certainly do some charter work for one or two government departments but that’s as a result of a competitive process. Sky Traders is another company that does similar work for the government and benefits from that same process.
Where do you get your information from?
