1 Pound - Victoria Union Bank of Australia

The Union Bank of Australia was a London-registered colonial bank operating branches across the Australian colonies, New Zealand, and briefly elsewhere — its notes circulated far from any British printing house. Perkins, Bacon & Petch were the dominant security printers of the mid-Victorian period, responsible for early postage stamps across the empire as well as a significant share of colonial banknote production. Their steel-intaglio work was chosen precisely because colonial authorities and bank directors worried about counterfeiting in remote communities where verification was nearly impossible.

The decade-long date range reflects reissue across multiple colonial jurisdictions rather than a single print run. Branch-specific overprinting was common practice for this series.
