USD to AUD Historical Exchange Rates

Key Milestones Since 1966

14 February 1966: Australia adopted decimal currency, replacing the Australian pound at A$2 = £A1. The new dollar was linked to sterling and worth about US$1.12 – so 1 USD bought roughly A$0.89.
1967: when Britain devalued sterling, Australia kept its exchange rate against the US dollar unchanged.
1971–1974: pegged to the US dollar; revaluations in 1972–73 lifted the AUD to around US$1.49 (about A$0.67 per USD).
September 1974–1976: pegged to a trade-weighted basket of currencies after a 12% devaluation.
November 1976–1983: a 17.5% devaluation, then a crawling peg adjusted in small steps.
12 December 1983: the Australian dollar was floated.
1986: a sharp fall to the high 50s (US cents per AUD).
April 2001: record post-float low, below US$0.48 (more than 2 AUD per USD).
2010–2013: above parity with the US dollar, peaking at about US$1.10 in July 2011 – see AUD/USD parity history.
March 2020: a brief drop to around US$0.58 during the COVID-19 sell-off.
