However, the price for Australia in Steam appears to be substantially higher, $27 USD higher… Using the two links below show two different prices, and unfortunately unless you have a US billing address, you wont be able to use the US store page.

Suggestions for getting the lower price range from illegal to legal, however probably the easiest legal method is to just get it gifted from someone in America then pay them back via PayPal.
