Which currency is commonly called the 'Aussie' in forex?

The currency commonly called the “Aussie” in forex is the Australian dollar.

The nickname distinguishes Australia’s dollar from other dollar currencies and is widely used in currency-market shorthand. Its ISO code is AUD, while traders may also write A$ or AU$ to avoid confusion with the US or Canadian dollar. In currency pairs, AUD/USD is often informally called “Aussie-dollar.”

Australia introduced the decimal dollar in 1966, replacing the Australian pound. The dollar is issued by the Reserve Bank of Australia and is legal tender not only in Australia but also in Kiribati, Nauru, and Tuvalu through monetary arrangements. Its value is influenced by commodity exports, China’s economic performance, interest-rate expectations, and global risk sentiment.

A common mix-up is confusing “Aussie” with “Kiwi,” the forex nickname for New Zealand’s dollar. The Canadian dollar is frequently called the “Loonie,” while Singapore’s dollar is generally identified as SGD.
