Opposition Leader Peter Dutton has blamed a slip in the polls on a perception of disunity in the Liberal Party, following the resignation of shadow frontbencher Karen Andrews yesterday.
In the new poll, published in the Sydney Morning Herald, Labor had increased its primary vote from 39 per cent to 42 per cent, while the Coalition dropped from 30 per cent to 28 per cent.
Dutton's personal approval ratings have hit a record low of -28 per cent, down from -11 per cent a month ago.

However, the Liberal Party has been dealing with some inner ructions on the debate around the Voice to parliament, with former shadow attorney-general Julian Leeser returning to the backbench over his personal position on the Voice, though he has remained committed to the Liberal Party as an MP.
Former Coalition Indigenous Affairs Minister Ken Wyatt quit the Liberal Party entirely over the same issue.

Andrews said her decision was not related to the Voice, and she has decided to not contest the next election.
Dutton said voters "rightly" did not reward perceived disunity within a political party, and said the Coalition faced a "big rebuild".
But he said the party remained united, and that he was committed to opposing the "elitist model" of the Voice.

"I also think a lot of families are really hurting at moment, the cost-of-living pressures continue to mount on people," he said.
"I think the public probably hasn't quite seen that Labor is responsible for making a number of decisions that clearly make it harder for families.
"Sadly for families, that will come home to roost over the next 12 months."
He defended the opposition's focus on the Voice as important for the country's long-term future, but said they were also focused on the ongoing pressures faced by Australians now.
