The Reserve Bank of Australia (RBA) board member John Edwards said on Friday that the Australian dollar was still too high.

"I guess I would say I still think it is a bit too high. If it was driven entirely by commodity prices, it certainly should be lower," he said, adding that he would be more comfortable if the Australian dollar was trading at around $0.65.

Edwards pointed out that if major central banks keep their negative interest rates, the Australian dollar could rise.

His comments could mean that the central bank is likely to ease its monetary policy further.
