.The issue was struck at the Royal Australian Mint in all years with additional assistance provided by the Royal Mint London
in 1966 to assist with the huge demand for new currency as a result of the vast amount of pre-decimal
currency withdrawn. In 1982,the Wales mint assisted with striking coins to meet the additional
demand for circulation currency brought about by the economic boom of the 1980s.
