I don't understand the furor. This appears to be a case of market economics. Australia has a population of ~25 million people, while the US has a population of ~300 million. The EU, likewise has a population of about 300 million. Simple economy of scale arguments provide a rational answer: Apple's cost per unit to ship products to the US and the EU is going to be lower than its cost per unit shipping to Australia, and those savings (or burdens depending on which side of the world you are in) get passed onto consumers. Not to mention the infrastructure costs of setting up stores, corporate offices, advertising, and a market presence in country with 1/10 of the population of the US or the EU. Which again will all result in a higher cost basis per unit sold in Australia. Finally, higher tax rates on corporations in Australia, higher employee taxes on business, and other regulatory issues are likely to drive up prices. Let's not forget the dreaded GST which makes the end price for consumers even higher.
Rather than whine about it, Australian MP's may consider what they can do to create a more favorable market for high tech products in Australia by providing tax benefits to offset the higher costs of doing business in a small and over regulated market.
