The Australian dollar was lower at noon, weakening under declining commodity prices and a strengthening US dollar.
At 1200 AEST, the Australian dollar was trading at $US0.8074/78, down from Friday's close of $US0.8149/54.
Since 0700 AEST, the unit moved between a low of $US0.8065 and a high of $US0.8100.
"It's come off a bit during the offshore session, mostly because of a recovery in the US dollar," said Nomura Australia chief economist Stephen Roberts.
"It was quite firm going back to Friday and stayed firm during our session.
"It's edged the Australian dollar back a touch."
Mr Roberts said the strength in the US dollar had held back rising prices amongst commodities.
The Australian unit is considered a risk-sensitive currency and typically rises or falls in line with commodity prices.
Precious metals fell in offshore trade, leaving them lower for the week. Gold for August delivery fell $US21.30 to settle at $US940.70 an ounce, and July silver fell 61.8 cents to $US14.875 an ounce.
July copper fell 7.15 cents to $US2.3735 a pound.
"That's counted a little bit against the Australian dollar," Mr Roberts said.
The recovery in the US dollar was spurred in Friday's offshore trade, by the Reuters-University of Michigan consumer confidence report coming in below market expectations.
The report showed US consumer sentiment improved slightly in June, but below market expectations: the index was up 0.3 index points in June to 69 points.
Economists had expected the index to rise to 71 points.
The measure of consumer sentiment towards current conditions rose, but consumers were more pessimistic about future conditions.
Inflation expectations for the year ahead rose to 3.1 per cent, from 2.8 per cent.
Mr Roberts said a lack of significant economic data would keep the local unit trading in a tight range around $US.08065 for the rest of Monday's session.
