The Aussie dollar at the mercy of offshore factors, has risen 1 percent this week despite soft inflation data on Wednesday that economists said ruled out any rise in official interest rates for months to come.
The US dollar dipped against the yen on Friday as attention turned to growth figures for the US economy due at 1230 GMT, while the euro kept its gains on growing expectations the European Central Bank will raise rates early next year.
The US economy likely grew 3.6 percent in the third quarter, speeding up from 3.3 percent in the previous quarter, according to a Reuters poll.
One Aussie fetched $0.7560/63 compared with $0.7565/68 late here on Thursday. It peaked at $0.7603 overnight, its highest since October 10.
It traded a tight $0.7557-$0.7577 range on Friday amid uncertainty about the near-term direction of the US dollar. Resistance is seen at $0.7600/10 and support at $0.7540.
"It seems possible we are developing a new period of weakness in the US dollar against safe-haven European currencies that may soon spread to the yen and Asia," said Greg Gibbs, senior currency strategist at RBC Capital Markets.
The Aussie retreated against the euro after European Central Bank officials reiterated the Bank's call for vigilance against inflation, suggesting future erosion in the Aussie's yield advantage over the euro with Australia's central bank stuck in neutral.
