Haven't been to Australia, so I cannot evaluate it fairly. I do know that their export stuff (e.g., Foster's) is horrible. Likewise, the beer that the English export here is pretty bad as well (with some exceptions, most notably, Abbott Ale).
I do however like English beer. And there is a lot of room for agreement and disagreement on the merits of various country's beers.
The one constant is:
American beer is like sex in a rowboat, it's f...ing close to water.
