Scott Morrison lugged bags of sand on to a truck at a Liberal-friendly small business, making the case to save government seats in Melbourne's east.
The prime minister also climbed aboard a digger at Daisy's Garden Supplies, continuing his penchant to jump in the driver's seat on Monday.
The business has been no stranger to coalition politicians over the years and the prime minister joined the club in the Liberal-held seat of Deakin.
The government is in danger of losing despite holding it with a 6.4 per cent margin.
"I am confident about the good judgment of Australians here in Deakin," he told reporters.
He was there to spruik the coalition's tax cuts for small business and increasing and expanding the instant asset write off.
If sandbagging seats was his aim, Mr Morrison gave the perfect imagery to accompany the mission, lugging bags of the stuff on to a truck for the cameras.
Deakin MP Michael Sukkar initially refused to answer questions, but relented when cornered with cameras.
Mr Morrison dumped the Peter Dutton-backer from the front bench after getting the top job, while Labor has launched attack advertisements noting Mr Sukkar's role in dumping Malcolm Turnbull.
"I'm very focused between now and the election on ensuring that we have a Morrison government continuing because I think he's the person to lead us," Mr Sukkar told reporters.
House of Representatives Speaker Tony Smith joined Mr Morrison and Mr Sukkar at a Croydon road project later in the day to announce a $154.5 million "congestion-busting" package.
Mr Smith also brushed off questions about the damage last year's leadership spill inflicted on the Liberal brand in Victoria.
"We're not looking through the rear-view mirror, we're looking through the front windscreen," he told reporters.
The Casey MP holds his seat, which borders Deakin, by a notional margin of 4.5 per cent after a redistribution reduced his buffer.
After talking up roads, the travelling party shifted gears to launch the campaign of Liberal candidate for Chisholm Gladys Liu at the Box Hill Golf Club.
Mr Morrison received a buoyant welcome from a multicultural group of supporters two days after awkwardly greeting a Korean woman in Mandarin.
"I'm no Asian languages expert, so I'm going to say g'day to everyone," he said.
Julia Banks won Chisholm for the Liberals at the 2016 federal election but left the party to sit as an independent after the leadership spill.
She's running in Flinders, potentially causing rocky seas for Health Minister Greg Hunt on the Mornington Peninsula.
Meanwhile, Ms Liu has a notional 2.9 per cent margin in her battle against Labor's Jenny Yang.
