Sydney down 0.2%

Australia's benchmark index was largely unchanged after the Reserve Bank of Australia (RBA) cut interest rates to a record low of 2.5 percent, as widely expected. But the move saw the Australian dollar add 0.5 percent to hit a three-day high of $0.8980 following it's overnight tumble to a three-year low.

The central bank said the rate cut was especially appropriate given recent tepid economic data as well as slowing growth in China, Australia's largest trading partner.

"The RBA cut interest rates by 25 basis points that wasn't a great surprise. I think one of the most interesting things the statement seems a little less dovish than previous statements as they didn't explicitly indicate that the inflation outlook provided them with scope for further easing from here," said Paul Bloxham, chief Australia and New Zealand economist at HSBC.
