Foreign exchange is the buying and selling of money from other countries. It enables you to pay for goods and services that originate in another country in the currency of that country.
The rate at which the money of one country is bought or sold for that of another is called the foreign exchange rate. For example, one Australian dollar might buy 80 US cents.
In Australia, we use a floating exchange rate system, meaning that the value of the Australian dollar can rise and fall from day to day, depending on the demand for our currency. An unexpected surge or slump in the value of the Australian dollar can put a hole in your pocket – or a smile on your face, depending which side of the fence you’re on.
For example, an increase in the value of the Australian dollar is good if you are planning to travel overseas, as it means you can buy more foreign money. If the dollar falls, then you may have to spend more Australian money to buy another currency.
You can also visit selected Commonwealth Bank branches and withdraw your foreign cash straight from one of our Foreign Exchange ATMs.
Our Foreign Exchange ATMs dispense cash in four major currencies: US dollars, Euros, Great British pounds and New Zealand dollars. Simply use your Australian issued debit or credit card* and you can withdraw up to AUD1,000 worth of foreign cash. Best of all, you'll know exactly how much your foreign cash will cost when you withdraw it, so there's no surprises.
