Extended data:

In the foreign exchange market, Australian dollar is now the sixth largest currency in the world. Second only to the dollar, euro, yen, pound and Swiss franc, accounting for 6% of the total transaction volume.

Since 2002, after improvement, all banknotes used in Australia are glued, which is not as fragile, durable and beautiful as before. In addition, it has also designed unique transparent "windows" for various denominations, which is the first country in the world to adopt this brand-new design.

The current Australian dollar is 5 10/0,20 cents, which is the same size as the previous Australian dollar, New Zealand and Britain's sixpence, shilling and two shillings.

1990, the New Zealand government, the core of the British government, reduced the size and weight of the nickel coin in 2006, with a new diameter of 3 1.5 1 mm and a mass of15.55g.. Australia's 50-cent coin has thus become one of the largest and heaviest coins.

In currency circulation, New Zealand's coins of 5 10, 20 cents and 1 yuan are very similar to those of Australia in size and shape, so they are often mistaken for Australian coins.
