<P> `` Gold '' one - dollar and two - dollar coins were introduced in the 1980s . The one - dollar coin was introduced in 1984 , to replace the banknote of the same value . The two - dollar coin , also replacing a banknote , was introduced in 1988 . These have content of 2 % nickel , 6 % aluminium and 92 % copper . Thus , all Australian coins in use currently are composed of more than half copper . The two - dollar coin is smaller in diameter than the one - dollar coin , but the two - dollar is slightly thicker . </P>
