The Australian dollar is slightly lower after a quiet night of trade with Wall Street and most European markets closed for public holidays.
At 0700 AEST on Tuesday, the local unit was trading at 78.24 US cents, down from 78.31 cents on Monday.
Paris' leading CAC 40 index ended Monday down 25.72 points or 0.50 per cent at 5,117.17 points, with trading volumes quite thin.
NAB senior currency strategist Emma Lawson said there was a bit of caution in currency markets as Greece's negotiations with its creditors drag on.
"Tick Tock, Tick Tock that's both the sound of time passing on one of the quietest days in the markets but also that of the countdown to Greece needing to come to an agreement with its creditors," she said.
"These were the strongest influences last night."
Greece will keep repaying its European Union and International Monetary Fund creditors for as long as it can, with some 300 million euros ($A422 million) due next week and a deal yet to come from talks over the country's remaining bailout funds.
Ms Lawson said commodity prices were generally higher overnight and the US dollar was stronger, which put downward pressure on the Australian dollar.
Economic data out on Tuesday includes the ANZ-Roy Morgan weekly consumer confidence index.
