Australia is a leading supplier of natural resource products. The country is self-sufficient in almost all foodstuffs and is a major exporter of wool, meat, dairy products, and wheat. Mining products form another key export sector. An increasing focus on services and high-tech industries has helped Australia diversify and modernize its economy. The Australian dollar is one of the seven major currencies involved in forex transactions, and accounts for approximately 5% of worldwide foreign exchange transactions. Its popularity is due to the fact that there is little government intervention in the currency market, and a general view that Australia has a stable economy and government. Due to the high dependence of the Australian economy on commodity exports, the Australian dollar is considered a resource currency that tends to reflect changes in mineral or agriculture prices.
