Here's an older pricing tier matrix I found through Google:

If you choose Tier 40, your app is:
US$39.99
€31.99
£23.99
¥4600
AU$47.99
Want to charge AU$32.99? Choose pricing tier 27, which also sets your American price to US$26.99
You could probably create a different app for each country to choose different prices, but that's about it.
