For starters, Australia is considered as part of the Europe region by NCSoft. Any units bought in Australia are shipped from England, so you should convert to Great British Pounds, not American Dollars.
At $89.95 that works out to £37.80, and RRP for GW:NF in the UK is £29.99. Now you have to add on a bit for the shipping to Oz, distribution costs and so forth, so we (Yes, I'm Aussie as well) really aren't being charged too much extra at all.
If you really feel the need to rant about it, blame the Australian dollars crappy exchange rate, although it has been getting quite a bit stronger as of late.
I am kind of surprised that your local EB is still charging full price, I bought a copy for my girlfriend for $50 just before Christmas.
*Edit* - Fixed a mistake in the prices.
