I do not believe I have seen Foster's for sale in Australia since I was a teenager. How is it possible that people in the United States are still drinking it?
He's making a funny. Foster's very much exists in the USA because it's like buying a 40 of Budweiser except you can pretend to be cosmopolitan. It does not, however, have much in the way of market dominance any longer. Carlton bought out the Olympia Brewery in the mid '90s, as well as Clearly Canadian. Thus, Foster's was produced indigenously from 1994 to 2003. It still has shelf presence, but no more so than Asahi, Chimay or Saporro.
Yeah sorry, I had to, it's like a running joke with my sister in Melbourne. There aren't many places here you can buy a Foster's, either. There are plenty of non-IPA (and IPA) local microbrews that you'll get into here. But yeah you might have to visit some of the breweries directly or go to a somewhat-specialty store, but there are plenty of both. I hope you have a good time! You should do a trip report, I'd love to hear about your experience. Call everyone "cunt"! (no, don't)
