Speaking during a visit to Westmead Children's Hospital in Parramatta on Sunday, Mr Morrison said "hard-working public servants" were set for the axe under Labor's plans.

Labor leader Anthony Albanese has warned Department of Prime Minister and Cabinet secretary Phil Gaetjens he is set for the axe if, as polling predicts, the opposition seized government on May 21.

But Mr Morrison, who defied polling to win the 2019 election, dismissed the comments as a sign of continuing overconfidence in the opposition camp.

"They're counting seats as having been won before a vote has been cast, let alone counted," he said.

"They've got a hit list of public servants that they want to take out of the system, hard-working public servants. They're getting quite ahead of themselves."

Mr Albanese in August refused to guarantee the jobs of a host of top-ranking bureaucrats, accusing the Coalition of politicising a notionally apolitical public service.

Apparently in his sights was Mr Gaetjens, Mr Morrison's former chief of staff who was tasked with investigating the government's handling of Brittany Higgins' rape allegation last year.

Labor also criticised Mr Gaetjens for refusing to make public his probe into the sports rorts saga.

While new polling from Resolve Strategic put the Coalition's primary vote support 1 percentage point above Labor's, Mr Albanese touched down in Byron Bay to finish his first week of election campaigning, first visiting an Anglican Church in Bangalow devastated by the recent floods.

He was joined by his partner, Jodie Heydon, along with senior frontbencher Tony Burke and Queensland senator Murray Watt.

The entourage then headed north where the Labor leader, flanked by his allies, joined punters at Byron Bay's Bluesfest.

Mr Albanese was introduced in front of the stage where he shook hands with festival-goers who were waiting for The Waifs.

The crowd cheered as Mr Albanese made an unscheduled through a fenced-off walkthrough in the centre of the moshpit tailed by the press pack.

The Labor leader was expected to join singer Jimmy Barnes on stage.

Both parties' leaders endured a challenging final day of their first week of the campaign, with Mr Albanese incorrectly stating he supported retaining temporary protection visas - then claiming he had misheard the question and correcting himself.

"Earlier on I heard half the question," he told reporters in Cairns minutes after a short doorstop interview while leaving church on Easter Sunday.

"Labor's policy is to support Operation Sovereign Borders. We support off-shore processing. We support processing in third countries. We don't support temporary protection visas."

The Prime Minister is staring down factions within his NSW branch of the Liberal party who want him to disendorse his hand-picked candidate in Warringah, Katherine Deves, over graphic language she used to describe transgender people.

Foreign Minister Marise Payne repeatedly declined to endorse a controversial candidate during an interview on Insiders.

"It is a matter for the organisation in NSW ... I don't agree with the remarks she made," Senator Payne said.

Earlier, NSW Treasurer Matt Kean called for Ms Deves to be disendorsed, but the Prime Minister rejected teh suggestion, declaring he does drop people from his team for saying "insensitive things".

During an announcement about additional funding for diabetes continuous glucose monitoring, the Prime Minister confirmed that Social Services Minister Anne Ruston would be health minister if the Coalition is returned to government by voters.

Mr Morrison said Senator Ruston had a "big heart" to be able to deal with the many issues faced in the health and aged care portfolio.

"She's demonstrated that in the social services portfolio - she's worked with people all over the country," he told reporters.
