Vegemite? Disgusting stuff.
Suggest you try Marmite (it's the REAL thing

). I could happily live on that stuff, if only it wasn't so expensive.
One reason the 'colonials' don't like it, is that most have never tasted
real Marmite ! The antipodean variety which carries that name is a totally different formulation. See Wiki for the history ...
Just love your Fosters, but Vegemite ain't for me. Maybe it's been designed for a sunnier climate ?
