But if I order from a UK retailer for example The Hut
Yup, it's expensive in Australia.
It's not just your games either, I spent last month in Brisbane and everything is half as much extra to double the price it is in the UK. Even a meal from McDonalds costs about £11 versus £5-7 in the UK, they include drinks in the price here too. Food prices border on the absurd.
I guess you're just screwed by geography, there are no small transport costs in Aus and you're an all but captive market. Being the only native English speakers that side of the planet (Kiwis excepted).
However, before you get all uppity about it, don't forget that you get to live in Australia. Also, I noticed that trains, buses and ferries are really cheap (and clean, reliable, politely staffed) compared to here, that and the weather I could get used to.
