Will a iphone 5 purchased in America work in Australia?

Hi

If I purchase a iphone 5 in America will it work it Australia with a Australian sim card as on the Apple website it shows some American carriers. If it will be locked it is there a way to get unlocked?

You will have the purchase the unlocked iPhone 5 for it to work over there. But, Apple announced they won't be selling the iPhone at the launch so it will be some time until they sell the unlocked iPhone 5

Another issue you have to contend with, when you can purchase an unlocked iphone 5 according to this article the the AGE, apple have configured G4 network that it work only in the country it is purchased in. So a US phone won't work properly in Australia

I understand it may be expensive per minute, but I just want to know if upon arrival I can step out of the airport dial a friend in Australia's number and it will go through. If not, what do I need to do to make this happen?
