the first clue is in the price of a beer at departure and arrival.
$9 for a bottle at Perth airport for instance and just a couple of dollars at arrival in Bali.
Even departing DPS the price is a third of that in Australian airports.
The universe may not revolve around the price of a beer, but its a good place to start!
