OK - interesting. Us Aussies often don't realise how big some of these bands took off overseas - as a kid I was oblivious to the fact that bands like LRB, INXS and Midnight Oil had done well outside of Australia. Most of the Aussie bands were just local but there were plenty of exceptions.
These days with Aussie metal/melodic rock , most of the bands here are much bigger in Europe than they are in their own country (Black Majesty, Lord, Teramaze, White Widdow etc...)
