What are the best live music venues in Australia?

For jazz, hit up Birds Basement in Singers Lane, Melbourne. Great venue. Corner Hotel. Classic

Belviour Amphitheater in the Swan Valley has been by far the most outstanding music venue ive been too!!!

Ghost rock vineyard at port Sorell in tassie has to be one of the best venues down under on the apple isle

I have to recommend Fly by Night Club in Freo, WA! It's not mainstream kind of music but cool, intimate gigs in a decent size venue. You will find many a bar in the cultural Mecca of Freo that often showcase the local talent.... Mojo's Bar is another one.

If you are going to head "down south" in WA, Caves House Hotel in Yallingup holds live music events. Or there is Settlers Tavern in Margaret River?
Of course there are hundreds of wineries in this region that over the summer months are host to many a live music event.
Sun+beach+wine+music = perfection!
