The Australian dollar was slightly lower as the US dollar continued to strengthen following last week's news that the US central bank may wind up its economic stimulus program.
At 6.30am AEST the local unit was trading at 92.12 US cents, down from 92.34 cents on Friday.
The local currency fell 3.5 per cent against the US dollar last week - the biggest weekly fall since September 2011 - after US Federal Reserve chairman Ben Bernanke signalled the central bank may soon start to wind up its stimulus program if the US economy continued to improve.
The announcement, along with weaker-than-expected manufacturing data from China, saw the Australian dollar fall against the surging US currency while local and overseas stock markets also have taken a battering.
