Scott Morrison and Anthony Albanese have traded blows over leadership as a pre-poll campaign blitz continues.
The prime minister is spending Monday touring marginal seats in regional Tasmania.
Mr Morrison used the visit to announce an $86 million grant for the state's forestry industry, pledging 150 million new trees.
Meanwhile, Opposition Leader Anthony Albanese is in Sydney, before heading to Tasmania on Tuesday.
Mr Albanese used a radio interview in Sydney to attack the prime minister, following a series of TV and live appearances by Mr Morrison.
"If you want a guy to shampoo your hair and weld without a mask on and all that, then play a ukulele, kind of, then Scott is your guy," he said.
"People are wanting him to do his job, and his job was to order enough vaccines."
Mr Morrison said the shutting down of rail services in NSW on Monday showed what would happen under a federal Labor government led by Mr Albanese.
"If people want to hand the country to unions under a Labor government led by the most left-wing Labor leader in 50 years ... this is what they can expect," Mr Morrison said.
The electorates of Bass and Braddon are must-hold seats for the government, with both being on slim margins.
The coalition holds Braddon by a little more than three per cent, while the margin is even narrower in Bass, at just 0.4 per cent.
The Labor-held seat of Lyons, which sits at just more than five per cent, also remains in play at the upcoming poll.
Mr Morrison said the visit would be one of many made to Tasmania between now and when voters go to the polls.
Despite incumbent Bass MP Bridget Archer crossing the floor earlier this month to vote against parts of the government's religious discrimination bill, the prime minister said she still had his support ahead of the election.
"In our party, we don't throw people out because we don't always agree on everything, that's the nature of the Liberal Party," he told reporters.
"Bridget is passionate, has come with life experience to our team that I greatly value and I greatly respect."
Both leaders had been out campaigning in the Northern Territory during the week, with the seat of Lingiari being a winnable seat for either party following the retirement of long-serving Labor MP Warren Snowdon.
The election is due to be held by May 21 at the latest, with the date likely to be finalised following the federal budget in late March.
However, business and community groups want the May election to be fought on more than just national security, particularly after two years battling the coronavirus pandemic.
"After an unprecedented two years, the nation faces major challenges," Anglicare Australia executive director Kasy Chambers says.
"Record numbers of Australians cannot afford a home. People out of work are struggling to make ends meet. And the climate crisis looms large as we face more extreme weather."
Anglicare has "five ideas" it wants tackled by the major parties - a basic income, a jobs guarantee, a community climate fund, a home for every Australian, and governing for all, which includes an inquiry into COVID-19.
