An angry Liberal voter interrupted Bill Shorten's fire and brimstone before a minor car crash injected more heat into a campaign barbecue.
The Labor leader campaigned in the marginal South Australian seat of Boothby on Tuesday, four days from election day, visiting volunteers and serving up sausages.
He was mid-flight on climate change action when Michael Ded, 83, began to interject, yelling: "Where do you get the money from?"
"I tell you what brother, we will stop giving tax subsidies to the top end of town," Mr Shorten replied.
Mr Ded blamed past Labor governments for sending Australia broke.
"How do you trust Labor?" he asked reporters after Mr Shorten's speech.
About 10 minutes after the speech, a driver crashed into a bin as they tried to leave but avoided major injury.
Labor's Senate leader Penny Wong was at the event, along with climate spokesman Mark Butler and Boothby candidate Nadia Clancy.
Senator Wong took aim at Liberal MP Nicolle Flint for avoiding questions while campaigning in the seat alongside Scott Morrison.
"Today we saw footage of the Flint sprint," Senator Wong said.
Long-term Labor supporter Doug Melvin, 73, was dark on the media for focusing on Mr Ded, but more positive about a victory on Saturday night.
"Only since 1971 - I'm pretty new to it," he told AAP when asked how long he'd be involved with the party.
James Cameron, 25, who works for the Community and Public Sector Union and has been campaigning in Boothby where he lives, says climate change and cost-of-living issues are cutting through.
"The majority of conversations I've had have been very supportive of what Labor stands for," Mr Cameron told AAP.
Earlier, Mr Shorten met with Jill Barnard and her husband Nev at the North West Hospital, not far from Burnie on the island's north coast.
Late last year, Ms Barnard's oncologist burst into tears when she told her the stage four cancer had spread to her liver.
"This is our third time trying to crack this monster. It's tough but we live every day," she said on Tuesday.
"We fight until we can't fight anymore."
Labor's big-ticket election promise is a $2.3 billion package to ease the cost burden on cancer patients.
Ms Barnard said the couple were out of pocket tens of thousands of dollars, giving the example of not wanting to wait for surgery as one pressure.
As the meeting wrapped up Mr Shorten, his wife Chloe and Ms Barnard shared an emotional embrace.
Labor is aiming to keep Tasmania Liberal-free, with the northern seats of Braddon and Bass under threat from the coalition.
The hospital was in Braddon, which Labor MP Justine Keay holds with a margin of 1.7 per cent after a by-election last year.
Mr Shorten also spent time in the Launceston-based seat of Bass, where Labor MP Ross Hart is gunning to repel a challenge to his 5.4 per cent buffer.
