Do they even sell Foster’s beer in Australia? I never saw any the whole time I was down there ...
You were not looking in the er.. right places.
They do. But it's not among the most popular choices. Not even in the top ten. It's not hard to get if you want it - most large bottle shops will have it - but you'll most often see XXXX (Four X), VB (Victoria Bitter) or one of the Tooheys' or Carlton's, especially on tap (apparently there's only about ten Pubs in the entire country that have Fosters on tap, and they largely do it for the nostalgia value.
