The Reserve Bank of Australia (RBA) Governor Glenn Stevens said in Brisbane on Wednesday that the central bank remains "open to the possibility of further policy easing" if it is needed for sustainable growth.

"The bigger point is that monetary policy alone can't deliver everything we need and expecting too much from it can lead, in time, to much bigger problems," the RBA governor added.

Stevens pointed out that there are a lot of countries that would prefer a lower exchange rate to boost exports.

He also said that he was concerned about housing property boom.
