Thanks 4 the kind welcome. vegemite is concentrated yeast, the by-product of making beer. it is very similar to marmine which is also the by-product of beermaking the main diff being unlike that warm brown water the english call beer. we here in australia know what beer is.
also in my 23 years on earth i have only once seen Fosters on sale. Australia makes some great beers and fosters isn't 1 of them. try a Tooheys, XXXX (4x), VB (Victorian Bitter), Casade, Coopers or Emu Beer
