An overwhelming majority of voters support the establishment of a federal Independent Commission Against Corruption, a nationwide poll has revealed.

A total of 80 per cent of respondents either strongly supported or supported the establishment of a federal corruption-fighting body, according to a poll commissioned by the Australia Institute, a Canberra-based independent think tank.

Of the 1420 people polled, only eight per cent were either strongly opposed or opposed to a federal corruption watchdog.

And should such a body be established, 78 per cent of people wanted the hearings to be held in public.
