SYDNEY (AFX) - The Australian dollar was little changed in quiet early trade with the unit expected to trade in a tight range due to today's public holiday in Sydney, dealers said. The unit traded between a high of 0.4921 usd and a low of 0.4906. A trader at a European bank said that with little clear direction from over the weekend, it is unlikely that the unit will see much activity today. "There isn't a whole lot to drive the market today, although the Tankan may provide some interest. I am expecting it to remain around current levels in the low 49 cents range until we have everyone back at work tomorrow and more from offshore," he said.
