Help identifying this copper token

Hi there. I haven't had much luck identifying this copper (or at least copper looking)  token. It's quite thin, same pattern front and back. I'm located in Australia but I have no history behind the coin. Thanks for your help!

Brewery Deposit Token. Ref Dean - potpourri of Queensland Numismatics; Shea - Food Numismatica of Australia

Thanks so much! I'll order the book.

Cheers:

Dean lists them as ‘Stock Tokens’ and the 1/- as being made by Amor - D795 21 mm

Shea calls them Brewery Tokens but does not show the 1/- in the series - B7 series of tokens 21.5 to 21.7 mm
