Oh, here we go, the Aussies found the thread. I'm seriously thinking of ordering a pack of Bundaberg, but the shipping costs on the glass bottles are brutal.
I've heard lots of good about Blenheim's Ginger Ale, and it comes in a "Hot" blend that apparently emphasizes the ginger taste...

That'll definitely be a gift for my father in law.
I would also enjoy some.
EDIT: My girlfriend just pointed out that Blenheim's doesn't have any actual ginger in it except for what they hide under the banner of "natural flavors." My enthusiasm is muted. Still want to try it, though.
