The Australian dollar was steady around $US1.0543 within $US1.0520 to $US1.0562 range, with worries about Europe's debt woes keeping investors wary of high yielders. It fell nearly one per cent on Friday.
Trading on the local unit was thinned by a public holiday but initial support was seen at $US1.0510 with resistance at $US1.0600.
The Australian dollar was also supported by the latest quake in New Zealand, which put the kiwi under pressure, with the pair rising to $NZ1.2951 from around $NZ1.2840. The pair hit a four-month low of $NZ1.2791 last week.
