Not really travel technology (Move the thread if you think it should be elsewhere pls mods) but it kinda is...

I'm an Aussie and have read a fair bit about Satelite Radio, but unfortunately there aren't products, afaik, similar available in Australia yet.

Because it works on Satelite technology, in theory [and we all know that Theory isn't always theoretical...] I should be able to buy a satellite radio and have it work over here. Does anyone know if this is in fact the case or if the product is currently limited only to use in the USA?
