Birds of Tokyo are sh*te thoWouldn't say that...
Karnivool
The Butterfly Effect
Devolve
Parkway Drive (though I'm not a huge fan)
AC/DC
Airbourne (AC/DC lite lol but still good)
The bloke from Karnivoll (Ian Kenny I think) has got a great voice.
You Am I are great live, never thought much of them till i saw them at homebake last year, great set and great atmosphere.
My favourite oz band is Frenzal Rhomb, although not sure they would fit rons description of 'good music.' Maybe if they wore a bit more spandex
There are some very good australian bands around however, Frenzal, The Living End were very good (and put on a good show), The Meanies, TISM were great, Parkway Drive, Children Collide have impressed me alot, The Herd are pretty damn good as well. If you ignore the sh*te like Eskimo Joe, Silverchair and Jet you'll be sweet.
