1 Pound Bank of Australasia

The Bank of Australasia was a London-incorporated institution that operated branches across the Australian colonies — never an Australian-chartered bank in any meaningful sense. Its notes circulated alongside those of locally founded rivals, but metropolitan oversight from Threadneedle Street meant conservative lending and, generally, conservative note design. Perkins, Bacon & Petch were the dominant security printers of the mid-Victorian period, their steel-intaglio process specifically chosen to defeat the colonial forgers who had already embarrassed several competing issuers.

The Bank of Australasia was absorbed into the Union Bank of Australia in 1951, making surviving pre-federation notes from any branch a finite population.
