No, Perth Airport just don't want to pay for a temporary customs and quarantine area to be installed over at Terminal 3/4.
Don't forget they've suffered a loss of traffic and passengers through the airport themselves with the drawdown in FIFO flying, and something like this would help boost passenger numbers, the airport's profile and their revenue a far greater amount than the funding that would be required.
Did VA contribute much toward that shiny new terminal they are now using?
Or maybe the state government will chip in, Barnett's government is facing a loss in next years election and this would be a coup if they could get it over the line. It'd be a lot less than they are spending on the new stadium anyway.
