A Productivity Commission analysis has found Australians are wasting thousands of dollars on fund regulations.

According to the paper, the Productivity Commission's major superannuation inquiry, released on Monday, members would reap more benefits if their savings were in larger, low-cost funds.

The Commission's paper also found the lack of real competition in the superannuation industry meant that there is little evidence to suggest benefits have been systematically passed through to members in the form of lower fees.
