hughbert,
Welcome aboard.
My local HBS sells them but I do not know your location in Melbourne.
Peter @
The Brewers Den
253 Dorset Rd Boronia

Best to give him a call and see what he has in stock.
Grain and grape sell them too
and I belive they are about to bring out a Grain and Grape brand fresh wort.
Quick and easy and much so much better than a can :super:
Hope this helps
Luke
