Cooper's Sparkling and Pale Ales are certainly my all-time favorites
I'm having one right now, two more in the fridge for whenever I want
Cooper's on tap isn't all that common though, but frozenstellar's right about Carlton draught being a good beer for a good price. It's everywhere, regular price, can't go wrong with it. I'll avoid VB as much as I can but if the choice is between VB and water, then it's VB for sure.
I also love Carlsberg but that's not Aussie.
