Gardner ends this press conference thanking David Speirs for his service to the community.

"He was a great local councillor, he was a great member for Black … he was a terrific minister for the environment … and he did great work as opposition leader."

"The Liberal party is now focused on the future."

John Gardner says the party will unite behind Vincent Tarzia who he says will have the support of the whole party.

"I'm very happy that Vincent Tarzia is our leader and we unite behind him and he'll have the whole team's support."

"All of us believe that the Liberal party's values are much better than Labor's. The Liberal party's values are the values that will serve our state well."

"I'm confident Vincent Tarzia will be the spear tip at the head of that charge that will throw the Liberal party in its best light."

Vincent Tarzia says David Speirs should "stay in the Liberal family".

Tarzia says he's confident he'll develop a "winning team".

"I want to develop that winning team and I’m confident I’m going to do it."

Tarzia says he didn't undermine former Liberal leader David Speirs.

"I absolutely did not undermine David and I consider David a friend. I want to work with David. In the Liberal party we need David."

Tarzia says South Australian families are "doing it tough" because of the cost of living. 

"We know that the average family here in South Australia is worse off by over $20,000 a year since Labor came to power."

"We know that the cost-of-living crisis continues to get out of hand here. We know that energy prices continue to get out of hand."

Incoming Liberal leader Vincent Tarzia says he will hold Labor to account on its promise to reduce ambulance ramping.

"The fact is ramping has never been worse here in South Australia, and there has been over 100,000 hours lost to ramping since Labor was elected."

Tarzia says the Liberal party will hold the Labor government to account.

"I'm willing to fight day and night, each and every day, with a strong team behind me, to hold the government to account, to put forward an alternative policy platform, to make sure that we earn the trust of South Australians, to win those hearts and those minds in the seats right across the state, whether they be in the regions, whether they be in the city, and we will be successful in 2026."

He says: "The Liberal Party will win the state election in 2026".

"Now, I know that there's many of you that thought that I wouldn't win around seven years ago, but what I'm here to tell Peter Malinauskas ... and everyone else, is no-one thought I would win back then, and I won."
