Bridge Road Brewery is the best in Aus by some stretch.
No way. Bridge Road is great, and I love that they do their range of single hopped IPAs (they're a brilliant tool for beer education), but in terms of actual beer quality there are a bunch of other breweries doing better stuff. Feral is the obvious one, but there are tons of smaller breweries like Moon Dog, Hopdog Beerworks, Bacchus, Red Duck, Riverside, more than I could even mention.
