Saw this from Windows Central(windowscentral.com),

£74.09 delivered, roughly converts to $156.37 AUD (1:2.11), VAT gets removed when you are at the checkout.
Right now, as far as I know, only place you could pre-order this in Australia is from EB games and MS Store (at AUD $199.95)
I believe the payment is made after the item is dispatched, so it's likely that the estimate would be off by the time it gets paid.
Possibly worth locking in the exchange rate with something nasty like a QantasCash or VeloctiyMoney card then if the cash is tendered at fulfillment, unless you're a gambler :D
