AUD to USD in August 2026: high, low, average
Updated September 26, 2026
The Australian dollar averaged 0.71018 US dollars in August 2026. It was a strong month for the currency: the first fixing on August 3 was also the low, 0.70066, and by August 28 the rate had reached its high of 0.71946. The month closed at 0.7162, a gain of 2.22% from the first day. These are cross rates calculated from 21 European Central Bank reference fixings.
What happened during the month
The Australian dollar rose on 12 of the 21 days and fell on 9. The biggest one-day gain came on August 21, when the rate added 0.87% to reach 0.71681. The range between the low and the high was 2.68%, wide for a single month, so the timing of a conversion mattered.
A useful way to read it: someone in Australia who received a US dollar payment on August 3 got the most Australian dollars for it, because the US dollar was relatively strong that day. An Australian paying a US invoice did better at the end of the month, around the high of August 28.
Year-on-year change
The comparison with August 2025 stands out. A year earlier the average was 0.64908. In August 2026 it was 0.71018, which is 9.41% higher. Against July 2026, when the average was 0.69639, August was up 1.98%.

The inverse figure, US dollars converted to Australian dollars, averaged 1.4082 over the month. That is the number to use if you think in terms of how many Australian dollars one US dollar costs.
Using the data for business
A company that sells to US customers and reports in Australian dollars earned less in local currency per US dollar of sales as August went on. If invoices are converted at the transaction date, sales booked early in the month translate at the most favourable rate for the exporter, and later sales at a less favourable one. Importers paying in US dollars saw the opposite effect.
For monthly reporting, the average of 0.71018 is a common choice when the accounting policy allows an average rate. For a single large payment, the exact fixing of the payment day is more accurate.
Keep in mind that the reference rate is a benchmark. Banks and payment services apply their own rates, and their margin often exceeds a week of normal market movement.
