How is the AUD/USD exchange rate calculated?
The AUD/USD rate here is the live mid-market rate — the midpoint between global buy and sell prices — drawn from professional market data and cross-checked with central-bank reference rates. It updates in real time.
Why does the AUD/USD rate keep changing?
Currencies trade on a global market all day, so the AUD/USD price moves constantly with supply and demand, economic news, interest rates and central-bank decisions. This page reflects every move instantly.
Will my bank give me this AUD/USD rate?
Usually not exactly. This is the indicative mid-market rate; banks and exchange offices add a margin and fees, so a real transaction is normally a little less favourable. Use it as a benchmark to compare offers.
Is AUD/USD updated on weekends?
The currency market runs Monday to Friday, so at weekends you'll see Friday's closing level until trading reopens. On weekdays it is fully live.
