it is an australian bitter
so I'm guessing Australia. And New Zealand. And most likely those chain aussie pubs you apparently have over in the Yewkay.

There's a Billabongs not far from where I live.
The closest thing they serve to an Australian drink though is Fosters, which I've been told isn't remotely Australian, by some Australians.

Hmm well it's very well known here, fosters,
but I'm not quite sure it's actually australian.
If you want Aussie beer - VB, Crown Lager, Red Duck and Cascade are what you want. Though you'll have a lot of trouble getting your hands on Red Duck - it's only a very small brewery (and less then two hours away from my house - yaaay!).

ahhh, now VB I've tasted.
At an Autralia day party this year. We also ate Kangaroo and Crocodile, mighty tasty stuff.
