I have a 5 dollar 1981 bill signed by the treasurer. Is this worth anything?
The Australian Dollar had not yet been floated in 1981 and was tied to the US Dollar. In 1981 One Australian Dollar was equal to One US Dollar. One Dollar AUD in 1981 had the purchasing power of about $2.85 AUD today. One Dollar AUD in 1981 had the purchasing power of about $2.64 USD today.
