1.000 Pounds

The Commonwealth Bank of Australia's £1,000 note was never intended for public hands. These were interbank clearing instruments, used to settle large-value transactions between financial institutions rather than pass through retail commerce. Actual circulation figures were tiny, and the survival rate reflects it — genuine examples are among the rarest Australian paper money items known.

De La Rue printed the series in London, consistent with Commonwealth Bank practice through the 1920s before domestic printing capacity was expanded. P#14A is the catalogued variant for this denomination and date, though documented auction appearances are sparse enough that population data remains thin.
