The Supreme Court of Western Australia as well as the independent Pacific Island states of Kiribati, Nauru, Papua New Guinea, Tonga, Tuvalu and Vanuatu use which abbreviation for their currency?
Australian dollar The Australian dollar (sign: $; code: AUD) is the currency of the Commonwealth of Australia, including its external territories Christmas Island, Cocos (Keeling) Islands, and Norfolk Island, as well as the independent Pacific Island states of Kiribati, Nauru, Papua New Guinea, Tonga, Tuvalu and Vanuatu. Within Australia, it is almost always abbreviated with the dollar sign ($), with A$ or AU$ sometimes used to distinguish it from other dollar-denominated currencies. It is subdivided into 100 cents.
Malagasy ariary The ariary (sign: Ar; ISO 4217 code MGA) is the currency of Madagascar. It is subdivided into 5 "iraimbilanja" and is one of only two non-decimal currencies currently circulating (the other is the Mauritanian ouguiya). The names ariary and iraimbilanja derive from the pre-colonial currency, with ariary being the name for a silver dollar. Iraimbilanja means literally "one iron weight" and was the name of an old coin worth ⁄ of an ariary.
