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. NOTE - This historical conversion is the result of many calculations and considerations by a purpose designed program for which I can take no credit. The resulting answer should only be regarded as an approximation.
