McNulty,
Quite easily, especially if you take the live out allowance. I have a 1 bedroom flat in a mid level neighbourhood which is quite nice and I make a profit of around $25 000 pa on the housing allowance alone.
Of course it is a remarkably small step from being a tight fist to being a big spender in this place. If you are earning a fat salary it is not unreasonable to spend $40k on a new 4x4 when you start justifying it to yourself(resale value, need transport anyway, safety on the roads, money just lying in the bank not earning interest, interest free company car loan, the Jones's, etc, etc).
