Barnaby Joyce has mocked mainstream conservative rivals in the Coalition, saying they are "splitting the One Nation vote", as recent polling suggests Pauline Hanson's party could form the next federal opposition.
A new poll revealed on the weekend by Ascent Research and RedBridge Group predicted that if an election were held today, Labor would return to power, and One Nation would win 53 seats.
The Liberals would retain a rump of 12 seats while the Nationals would be wiped out.

It also predicted the Liberals would lose all their seats in Queensland, South Australia, Tasmania, and Western Australia.
"I'm really disappointed the Liberal party's splitting our vote," Joyce told Today.
"Don't split the One Nation vote."

Taking a more serious tone, he said One Nation would not get "carried away" with the poll numbers.
"It's a poll, it's indicative, it's not the vote on the day," he said.
"It's an incredible honour that's been indicated, but there's a lot of time between now and the election."
Joyce, who served as deputy prime minister at times when he was leader of Coalition partner the Nationals, said One Nation sought to fulfill Australia's potential, a task he claimed should have been completed "decades ago".
"We will negotiate on supply in confidence (with the Coalition) if that's what required, but we will do so in exchange for policy," he said.
"One Nation does not care if you don't like them, they're going to be straight with you."
