Mark Speakman might have won about 70 per cent of the vote for the Liberal party in Cronulla, but he says it's not a safe seat.
Mr Speakman and other candidates commented on the election outcome, which saw the Liberal Party achieve another clean sweep in Sutherland Shire.
"Despite the fat margin, I never take Cronulla for granted," Mr Speakman told the Liberal Party faithful at Doltone House on Saturday night.
"I never, ever call Cronulla safe because no seat is safe.
"If you sit there and become complacent and think you've got it made, you will get a kick up the backside and probably be kicked out."
As earlier reported, Lee Evans, who was locked in what a Liberal source described as "hand to hand combat" in Heathcote, told the gathering Premier Gladys Berejiklian was so worried about the outcome she called him "every night".
"Gladys said, 'If we lose Heathcote, we lose the election," Mr Evans said.
"I said, 'Don't worry, I've got your back covered'.
"She said, 'No pressure".
Mr Evans said it had been "a hard slog" as they were up against the resources of the trade union movement.
He said one of the most pleasing results was winning the two booths in Helensburgh, which had once been a rock solid Labor area.
Re-elected Miranda MP, Eleni Petinos, who increased her margin by 2.2 per cent, took a lighthearted shot at Mr Speakman for possibly giving her Labor opponent Jen Armstrong her "celebrity status".
Mr Speakman chose Ms Armstrong as Cronulla Woman of the Year before she went on to be named NSW Woman of the Year.
"Despite that, and despite the number of times the candidate self promoted, it wasn't enough to convince the public the Liberal Party hadn't delivered for the constituents in Miranda over and over again during the last four years," Ms Petinos said.
"I want to say a big thank you to the people of Miranda for investing their trust in me for another four years."
In a Facebook post on Saturday night, Ms Petinos said, "Thank you Miranda!"
Ms Armstrong did not take up the Leader's invitation to respond to the jibe.
On election night, Ms Armstrong said, "I think we fought a very good, clean fight".
"No matter what the outcome, I am very proud of my volunteers and the support from the community and the opportunity to meet new community groups and individuals,' she said.
"It just makes me want to be involved in this area at a deeper level.
"Being in Sutherland Shire is always going to be hard, but it doesn't mean I am giving up."
Sutherland Shire's Liberal mayor Carmelo Pesce said, over the last few weeks, council staff had removed 2000 signs that were attached illegally to trees, fences and other public places.
Cr Pesce said most were signs supporting Labor candidate for Heathcote, Maryanne Stuart.
"Our public safety guys have done nothing else for the last two weeks," he said.
Ms Stuart did not reply to a request from the Leader for comment on the signs or on the result in Heathcote.
In a Facebook post, Ms Stuart congratulated her volunteers and campaign team for their hard work.
"Over the past 2 1/2 years we doorknocked, ran mobile offices and met many commuters, rain hail or shine," she wrote.
"Thank you to Kaila Murnain and all at Head Office for all your help and support.
"To my NSW Union family, thank you. I'm proud to be Union.
"But, last night the Heathcote electorate voted and although we reached a significant swing to Labor, not enough to get us over the line. Sorry!
"Still, I wake with peace. I have the most beautiful family, so blessed. Truly my backbone and strength.
"Look forward to spending fun time with them again.
"And I have so much hope and opportunity ahead.
"We built capacity as we campaigned, signed up many new ALP members, young ones too. Looking forward to working with each of them.
"It has been a pleasure and an honour to be the NSW Labor Candidate. Thank you."
