Billson rules out super access changes

Acting Treasurer Bruce Billson has dismissed as "a drop in the ocean" the $7 billion in budget savings that would be created by increasing the age at which Australians can access their superannuation.

Mr Billson was responding to new modelling from the Productivity Commission, released on Tuesday, reiterating the government had no plans to make any adverse, unexpected changes to super.

"The Productivity Commission report is a useful contribution to the tax white paper process, but that's it," he told ABC radio.
