A national anti-corruption commission will not be established before the next federal election, with the government refusing to introduce draft legislation to Parliament unless Labor supports it.

Prime Minister Scott Morrison first announced a Commonwealth Integrity Commission (CIC) in December 2018, alongside then attorney-general Christian Porter.

Despite years of consultation and draft legislation being released, the Coalition is refusing to introduce the bill to Parliament.

The government has tried to paint it as a test for Labor, arguing it needs to support the proposed anti-corruption watchdog model before it is even debated in Parliament.

That is despite the Coalition having introduced numerous pieces of legislation over the last term of Parliament which did not have cross-party support.

A spokesman for Attorney-General Michaelia Cash, who inherited the model from Mr Porter, said there were only a number of sitting days left before Australians head to the polls.

"We're prioritising religious discrimination and online trolling legislation because these have a better chance of passing in the remaining period," he said.

"If Labor want to vote with us on our CIC legislation we could pass it before the election."
