I can't fecking believe Pat is listening to Paul Kelly! (Peter, I deal with you later)
Much thanks Peter. Your musical batting  average is a perfect 1000.  More than I can say for a lot of others recommendations (Sorry to say)

 Yes Pat, all of the Aussie Bands you listed were popular with mainstream America at one point in their respected careers. However, ther is a huge melting pot full of great Aussie and Kiwi bands for you to descover. I'm sure Pete and our lovely friends down south, Kathyrn and Al, will help you with some segestions.

I say try The Go-Betweens next. Start with "16 Lovers Lane" then work back.
I'll give them a listen...Thanks
