100 Pounds

The London Bank of Australia Limited was a British-registered institution operating branches across the Australian colonies and later states, and by 1910 it was already in the late stage of its independent existence — the bank merged with the English, Scottish and Australian Bank in 1921. High-denomination notes of this type were instruments of interbank settlement and large commercial transactions, not retail currency, which is precisely why surviving examples are so rare.

No date of issue was printed; individual branches completed details by hand at time of use. That practice, combined with the note's face value, means virtually every known survivor came from bank records rather than public circulation.
