The Australian dollar has jumped back above the US79¢ mark, buoyed by strong employment numbers and as the greenback retreated after minutes of the US Federal Reserve's last meeting revealed worries about persistently low inflation.

The Aussie was fetching US79.41¢ in late trade, up from a one-month low of US78.08¢ it fell to on Tuesday.

Data on Thursday showed employment numbers rose by 27,900 in July, their 10th straight monthly gain, taking the unemployment rate to 5.6 per cent, from 5.7 per cent in June.

The gain in employment was solely due to an increase in part-time work and economists said the data would do little to change the Reserve Bank of Australia's neutral policy stance.
