Just checked with a vegetarian friend who uses TVP.
She says Citysuper has Bob's Red Mill, small unflavoured. Health Gate also sells Bob's Red Mill but is out of stock currently.
Great has no-name small unflavoured. It might also have chunks but she doesn't use them so can't recall 100%.
She says she remembers seeing one place that had flavoured (she doesn't use it) but can't remember where. If she remembers she'll tell me and I'll post it here if you want the flavoured variety.
