Cannot change App Store Country I am in the US and want to download an app, only in the US Store.

I tried changing the App Store Country, but seem to hit an impasse.

When entering my Credit Card details I cannot select Australia as the billing address.

I have 2 MasterCards, one Travel Money card with $US, and my Australian card.



I give up - this is apparently not possible!

I can't change App Store Country without changing Family Sharing.
A valid US postal address (could be your current hotel) is needed, and then you need to select NONE at the credit card - because you just buy some US iTunes gift cards, and load them into your new US Apple ID account, from where you'll pay for the apps you download.

And you can still use this US Apple ID when you are back in Australia - for app updates and new purchase from the App Store.
