This Aussie expat is very thankful for our local Tesco always having Vegemite stock. They also stock Bundaberg Ginger Beer (try it if you haven’t, another Aussie favourite).
Slightly surprised to find Bundaberg is actually drunk by Aussie's - cynical me always assumed it was marketing like Fosters.
For people who like that sort of thing, it might be worth looking at Euthymol toothpaste. It tastes like a mix of root beer, jagermeister, germolene antiseptic and pink.
