First-term Liberal MP Nicole Flint is fighting to hold on to her marginal south-west seat of Boothby, held with a margin of 2.7 per cent.

But a YouGov Galaxy poll prepared for The Advertiser has support for Ms Flint at 57 per cent compared to 43 per cent for Labor’s Nadia Clancy on a two-party preferred basis.

That would deliver Ms Flint a slightly increased majority if it’s reflected on election day.

The poll quizzed 520 voters in Boothby, with little support recorded for Clive Palmer’s United Australia Party.

Only three per cent of voters said they would give the UAP their first preference vote.

It also revealed strong support for Morrison, with 49 per cent considering him their preferred PM compared to 36 per cent for Opposition Leader Bill Shorten.

Morrison is today expected to talk up infrastructure spending and the strong relationship between the state and federal governments, while Shorten is targeting climate change as a key issue in Boothby.

A Labor attack ad accuses Tony Abbott of denying climate change, Malcolm Turnbull of getting dumped over it and Scott Morrison of ignoring it.

It also takes a shot at Barnaby Joyce for bungling climate action.

“And they’ll suffer from it,” the voiceover says as a picture of children is shown.

“The chaos within the Liberal-National government is out of control but it’s nothing compared to the chaos of a Morrison-Palmer-One Nation government.”

Morrison will later today fly to Geelong to lend junior minister Sarah Henderson a hand as she faces a similar battle in Corangamite.

Morrison is promising to create up to 350 new jobs through a new military weapons contract for the Australian Army.

“We will build and maintain them in Geelong, drawing on the large manufacturing skills base in the region,” he said on Tuesday.

The prime minister will then switch from defence to attack when he jets south to Tasmania.

The coalition is trying to win back the swing seat of Braddon from Labor MP Justine Keay.

Morrison will stick to the basics in his last-minute pitch to local voters, pledging $40 million to improve road safety and traffic congestion on a notorious stretch of the Bass Highway.

In Perth yesterday, the prime minister called Western Australia the “the true heart of aspiration in the country”.

“When you come to Western Australia, you come to a state where people know if you want to get ahead, you’ve got to have a go,” he said.

But Julie Bishop contradicted Morrison after he described China as a “customer” to Australia earlier in the day.

“I don’t see it that way at all,” the former foreign minister told reporters.

“I think our relationship with China is one of deep and mutual respect.

“We are partners. We are trading partners. We have worked together in a whole range of areas.

“And so, the relationship is one of equals.”

Besides climate change, Shorten is continuing to focus on health and wage rises.

The Labor leader has written to the Fair Work Commission, signalling his intention to withdraw the current government submission on award rates and resubmit his own if elected to government.

It further signals Labor will put the pressure on the independent umpire to give a wage rise to 2.3 million low-paid workers.
