Complete Guide to Australian $20 Paper Banknotes – Full List, History, Collector’s Value & Price Chart

The Australian 20 Pound note is one of the most iconic and valuable pieces of pre-decimal Australian currency. Issued before the transition to decimal currency in 1966, these notes hold significant historical, numismatic, and collector interest. Their large denominations meant they were used mainly for high-value transactions, and because fewer people handled them, surviving examples today can be extremely rare — especially in pristine condition.

This guide covers the entire history, design changes, security features, rare varieties, price values, and collector tips for the Australian 20 Pound note, making it the most comprehensive reference for enthusiasts and investors.

1. Historical Background of the Australian 20 Pound Note

Pre-Decimal Currency Era

Before February 14, 1966, Australia used the Australian Pound (£), which was divided into 20 shillings. The 20 Pound note was the highest denomination in general circulation, equivalent to about $40 AUD after decimalisation — though its purchasing power at the time was much higher.

2. Issuing Authorities

Different issuing authorities meant variations in signatures, designs, and watermarks, all of which now influence the note’s collectible value.
