South Australian Premier Peter Malinauskas has been blindsided by the abrupt resignations of two of his most senior ministers. Deputy Premier Susan Close and Treasurer Stephen Mullighan have announced they will retire from politics, sparking an immediate and deep reshuffle of the cabinet. (News.com.au)
The Shock Departure
- Both Susan Close (Deputy Premier, as well as Minister for Climate, Environment and Water, among other portfolios) and Stephen Mullighan (Treasurer) will vacate their roles by this Friday and will not contest the next state election in March 2026. (News.com.au)
- Each informed Premier Malinauskas privately weeks ago of their intention. He says he tried to persuade them to stay, but they were resolute. (News.com.au)
- Both cited personal reasons. Ms Close, who has been in Parliament since 2012, spoke of a sense that “life is short,” especially with the health challenges facing her family. Mr Mullighan, elected in 2014, emphasised the strain on his family and a desire to pursue other opportunities beyond politics. (The Australian)
Cabinet Reshuffle: Who’s Stepping Up
To fill the void, Malinauskas has moved quickly:
- Kyam Maher, currently Attorney-General and Leader of the Government in the Legislative Council, has been chosen as the new Deputy Premier. (Adelaide Now)
- Lucy Hood (Adelaide MP) and Rhiannon Pearce (King MP) will be elevated into full ministerial roles. (Adelaide Now)
- Nadia Clancy (Elder MP) will become an assistant minister. (Adelaide Now)
The swearing-in of the new ministers is set for Friday. (News.com.au)
Implications and Reactions
For the Government
- Malinauskas described the departures as “very disappointing,” but expressed gratitude for their service. He acknowledged the challenge of replacing two top-tier ministers so close to an election. (Adelaide Now)
- There is no suggestion of scandal linked to either minister’s exit. Both resigned independently, and neither departure appears to result from external pressure. (The Australian)
For the Opposition
- Vincent Tarzia, Leader of the Liberal Party, seized upon the resignations, accusing the outgoing ministers of “abandoning ship” and the government of instability. He has raised concerns about timing, pointing to poor unemployment figures and bearing the resignations as a distraction from those issues. (Adelaide Now)
What This Means Moving Forward
Governance and Policy Continuity
With the election looming in March 2026, the change at the top of key portfolios could affect ongoing policy work. Climate, environment, water, and finance are deeply technical and sensitive to consistency. Ministers stepping into these roles must rapidly get up to speed.
Electoral and Political Calculus
- Labor enters the final phase before the election facing voter scrutiny over financial management, environmental outcomes, and its ability to deliver on promises. These ministerial shifts could impact perceptions of stability.
- The new leadership in those roles will be closely watched. Voters will watch for whether Hood, Pearce, Clancy (and Maher as Deputy Premier) bring fresh energy, credibility, and results in their portfolios.
Strategies for Malinauskas
To minimise damage and maintain momentum, Malinauskas will need to:
- Clearly communicate why the changes were necessary and why replacements are qualified.
- Ensure transparency in how portfolios will transition—who holds what, and how responsibilities will be managed.
- Deliver early wins in newly assigned portfolios, especially in areas of concern like finance and environment, to reassure voters.
- Manage internal party morale, especially among those who may have expected elevation or felt overlooked.
The Big Picture
Labor’s government was elected in 2022 with a strong majority. It has since been operating under considerable expectations—on health, climate action, infrastructure, and cost of living. (ABC) The Premier has navigated prior reshuffles, but losing both the Deputy Premier and Treasurer so close to the election is major. It’s not just leadership vacuum; it’s a test of the Government’s resilience.
Bottom Line
Peter Malinauskas now faces the imperative of stabilising his administration. His response to this sudden loss of senior ministers will be a defining moment. How he handles the handover, keeps policy on track, and maintains public confidence may significantly impact Labor’s fortunes in 2026.
