Australian fifty-dollar note The Australian fifty-dollar note is an Australian banknote with a face value of fifty Australian dollars (A$50). It is currently a polymer banknote, featuring portraits of David Unaipon and Edith Cowan.
Coins of the Australian dollar "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.
