I thought the ginger beer was pretty good. What brand do you like? My favourite Aussie ginger beer is Cascade from Tasmania. I buy whichever is on sale.
Oh, you have a bundaberg in your fridge! Don't like their ginger beer much (doesn't taste gingery enough) but their root beer is amazing!
On the other hand Bundaberg rum is godawful. Actually, I have only tried the yellow label stuff. I would only try the others if I could get a tiny nip-bottle.
