They don't sell Fosters in a lot of places, the bottle shop and supermarket nearest me don't have it. And I have not seen anyone drink it in decades. Cafes and restaurants don't carry it. I think it exists mostly as export.
We do have MANY wonderful beers, including mainstream commercial ones.
Oh and as to cheap, taxes make sure beer is not cheap here compared to the US. There''s no super cheap ones. Cheapest you could possibly go would be 12.00 for a sixpack of not great beer on super sale, most of the time expect to pay several dollars more than that for non-craft beer.
