Matt Kean

Following the resignation of Berejiklian, Dominic Perrottet was elected as leader of the Liberal Party of New South Wales and sworn in as Premier. Kean was selected by Perrottet to succeed him as Treasurer of New South Wales, and was sworn in on 5 October 2021. In a December 2021 rearrangement of the Perrottet minister, Kean was appointed as Minister for Energy, and retained the portfolio of Treasurer.

Matt Kean was involved in a sexting scandal in February 2018, texting Liberal MP Eleni Petinos to seek sexual intercourse while at the same time involved in a relationship with an adviser in Prime Minister Malcolm Turnbull's office, Caitlin Keage. Ms Keage subsequently shared the illicit text messages with the media, describing it as predatory behaviour by Kean. NSW Premier Gladys Berejiklian described Kean's conduct as extremely disappointing and Kean apologised in a media statement. This followed an earlier relationship scandal involving Kean in 2016, when a former partner said on Facebook, then retracted, that Kean had been “screwing” one of Turnbull's advisers.

Kean previously served as the Minister for Innovation and Better Regulation from January 2017 until March 2019 in the first Berejiklian ministry and as the Minister for Environment from April 2019 until December 2021 in the second.

Following the resignation of Mike Baird as Premier, Gladys Berejiklian was elected as Liberal leader and sworn in as Premier. The Berejiklian ministry was subsequently formed, with Kean sworn in as the Minister for Innovation and Better Regulation, with effect from 30 January 2017. Following the 2019 state election, Kean was appointed as the Minister for Energy and Environment in the second Berejiklian ministry, with effect from 2 April 2019. Kean became embroiled in controversy soon after his appointment. In one of his first acts as Energy Minister, Kean appointed former Prime Minister Malcolm Turnbull inaugural chair of the government's net zero emissions advisory board. One week later Kean sacked Turnbull from the role, with Turnbull claiming Kean was pressured by right-wing media to do so.

Following announcement of the retirement of the sitting member, Judy Hopwood, Kean contested pre-selection for the safe Liberal seat against Hornsby Mayor, Nick Berman, and Hornsby Councillor, Steve Russell. Kean won endorsement and Berman announced his decision to resign from the Liberal Party and run against Kean as an independent candidate at the 2011 State election. At the election, Kean was elected; however, the party suffered a swing of 3.5 points. Kean won the seat with 62.1 per cent of the two-party vote, with Berman being his main rival.

Kean grew up in the Wahroonga area and was educated at Saint Ignatius' College, Riverview before attaining a Bachelor of Business from the University of Technology, Sydney. He later completed a graduate diploma at the Institute of Chartered Accountants. While at university, he was elected to the UTS Student Representative Council and as the SRC Executive Member for the Haymarket Campus. Kean has been a member of the Liberal Party since 2001, and in 2008, he was elected vice-president of the NSW Young Liberals. During the 2003 State election campaign, Kean worked as an adviser for the Leader of the Opposition, John Brogden. He subsequently worked for Catherine Cusack MLC as an adviser while she was shadow minister for Juvenile Justice and Women.
