Actually, it's pretty scarce right now.
Imports were banned due to containing foliate - simultaneously with the government urging pregnant women to eat more foliate. Typical.
The Indian grocery nearest here has had plenty in their "Anglo-Indian" section a month ago but they've been wiped out and have only Marmite now.
Hmmmm . . . that's interesting - the Firefox spell checker knows Vegemite but not Marmite - and I checked spelling against Peter's post.
