Yep, I'm Australian, but parted from my homeland at present, so in answer to your question regarding Vegemite - yes it IS that good, and I would sell my soul to be able to get my hands on some over here
Don't let those Brits and their *shudder* Marmite fool you, Mighty. Vegemite can cure all that ails you, no breakfast is complete without it.
That said, you either love it or hate it.
