iTunes and App Store in US store but I'm in Australia

I heard a song last night on a tv show and used the app "shazam" to find it. When It took me to the iTunes Store it said something about this song is only available in the US and it said something like would you like to switch stores so I pressed "OK". But this morning I realized on the App Store my featured page was completely different to my featured page on my iPhone and also in the music app I have iTunes Radio just on my ipod and I'm in Australia and I know it's not going to be available til next year. So I'm wondering how I get my ipod back to the Australian stores.
