Brewcraft at Henley Beach Rd Torrensville or Main South Rd Reynella.
I have seen them in Harris Scarfs and some supermarkets Coles or Woollies and I am not 100% sure but I think Coopers has something to do with them.
Didnt know you had them and didnt know you were posting as we all came on wit the answers at about the same time.
Most grain brewers support the shops that support the grain brewers if you know what i mean!!
