100 Pounds

The Bank of Australasia was a British-chartered institution headquartered in London, not an Australian central bank — a distinction that matters here. Perkins Bacon had a long relationship with the bank, supplying engraved notes from London throughout the colonial and early Federation periods. This £100 note, issued around 1910, would have been used almost exclusively for interbank settlement and large commercial transfers; retail customers rarely if ever handled denominations of this size.

The bank was absorbed into the Union Bank of Australia in 1951, after which remaining unissued stock was withdrawn. High-denomination survivor notes from this series are exceptionally rare in any condition.
