SYDNEY (FWN) - The Australian dollar was little changed in thin trade in late afternoon ahead of interest rate decisions in the US overnight and in Australia tomorrow morning, dealers said. The unit traded between a high of 0.5112 usd and a low of 0.5087 during the day. A dealer with Macquarie Bank said the movement was exaggerated in thin trade due to the Melbourne Cup. He said the market does not expect the Reserve Bank of Australia to lower interest rates tomorrow but expects the US Federal Reserve to cut rates by 50 basis points tonight.
