Could an American working for COCA COLA in the USA come to Australia and start loading trucks with pallets of COKE ?
So what do you see as the dividing line here?
IBM can make a sale, send software / hardware engineers to Australia who install the software / hardware and have them leave.
Why shouldn't an airline be able to make a sale, send an aircraft and crew to Australia who transport people and have them leave?
What's the underlying philosophy here?
The ADF use a charter flight with foreign crew that lands as first port of call in Darwin then several domestic legs. Is anyone suggesting that is wrong?
