It wasn't a baby, but Malcolm Turnbull has planted his first kiss of the election campaign.
The lucky receiver was 84-year-old Audrey Pratt who admits he didn't need a kiss to win her over.
"It felt very, very special," she told AAP after meeting the prime minister on Friday.
That's because he has her vote locked up for July 2.
Mr Turnbull had his first real campaign encounter with voters on Friday, walking through a shopping centre in the Adelaide suburb of Glenelg.
The centre sits in Hindmarsh, the coalition's most marginal seat in South Australia, won by Matt Williams in 2013 with an eight per cent swing.
To stay in parliament he needs to head off a challenge from Labor's Steve Georganas - the MP he beat three years ago.
The prime minister was greeted by applause as he entered the shops before sitting down for coffee with local mum Britt Hywood and her daughter Scarlett.
"It was a shock, very unexpected," she told AAP.
"But it was wonderful, he's very personable and relatable so it was lovely having a conversation with him."
Ms Pratt agrees and, despite her age and a bad knee, wasn't going to miss an opportunity to meet Mr Turnbull.
Even if it meant barging through the sizeable media scrum surrounding the prime minister.
"You've got to be out there. It's no good sitting back and thinking I'm 84 and I'm old and I can't do anything."
Ms Pratt reckons the best thing about Labor leader Bill Shorten is his beautiful wife Chloe.
At least one woman wasn't so impressed the prime minister stopped by.
"What are you going to do about the homeless people on the street?" she yelled before being carted off by the prime minister's security squad.
It was a day of firsts for the prime minister, who earlier made the coalition's first campaign pledge in Boothby, a relatively safe Liberal seat.
The area will have a city rail line extended to the Tonsley campus of Flinders University at a cost of $43 million.
Mr Turnbull also broke his radio silence giving an impromptu interview to a local station while riding a train out to the announcement.
But he preferred not to reveal whether he scrunched or folded his toilet paper, when asked by the station's reporter.
Mr Turnbull goes head to head with Mr Shorten in a televised forum with 100 swinging voters in western Sydney on Friday evening.
