There's an old saying, "When in Rome, do as the Romans do!".
You're in a new country, try some of the local brews, they make some very nice beers there!
I have found Mousehead in most bottle shops and saw Labatt's Blue in a "1st Choice" bottle shop in Concord last month. Those are the only two Canadian beers I have seen in my 6 years here.
Theres a pub/restaurant/bar on bondi rd called the flying squirrel, i believe its canadian owned and everyone working there when I went was canadian, they have kokanee there but its the only place ive seen it in 3 years.
