My experience was that Foster's is their Budwesier. It's relatively cheap and sells a lot, but no one considers it to be "good beer".
But it is, in fact, Australian? I didn't know that. I thought the whole thing was faked.
That reminds of a joke I heard in Australia:
Q: Why is American Beer like making love in a canoe?
A: Because it's fucking close to water!
Did you hear that before, or after, Eric Idle said it in Monty Python Live at the Hollywood Bowl
