Scott Morrison will face his first turn of parliamentary questions as prime minister, and an optimistic Labor opposition is expected to focus on the coup that broke the Liberal Party.

The latest Newspoll shows that the government is still controlling the reaction of the public to the spill that toppled Malcolm Turnbull as prime minister last month.

While Morrison overtook opposition leader Bill Shorten as the preferred prime minister, the coalition has slipped even further in the preferred terms of the two parties, falling behind from 44 to 56 percent.

The result will give even more energy to the Labor opposition, which will try to hit the government in question on why they felt Mr. Turnbull had to leave.

Interior Minister and Turnbull challenger Peter Dutton will also be pressured on two other fronts: the problem of the au pair visa and his eligibility to sit in parliament.

The coalition will no longer have a majority in the lower house, with Mr. Turnbull now out of parliament and the national deputy Keith Hogan promising to move on to the bench.

Labor MP Tony Burke told ABC on Sunday that Mr. Dutton should refer to the High Court after "confusing parliament" and supports a motion of distrust in him.

"There is no doubt that it is a legal question mark, he has a very important job for Australia and it is essential that he do it legally, the right thing to do is to self-refer," he said.

The deputy leader of the Nationals, Bridget McKenzie, told ABC on Sunday night that it was a decision for Mr. Dutton if he referred to the Superior Court.

He said that when the parliament and the deputies do not address the real problems, punters punish them at the polls, as was seen in the elections in Wagga Wagga.

"It reflects how parliamentarians and parliament are perceived, when we are not talking about the things that matter to real people in their communities, they punish us with reason," he said.

Several deputies, including Mr. Morrison's vice president and treasurer, Josh Frydenberg, will not be in Parliament as they take time to commemorate Rosh Hashanah, the Jewish New Year.
