Victoria's ex-COVID chief Weimar exits as Carroll reshapes leadership

Carroll reshapes Victoria's senior bureaucracy in his opening weeks
The new premier has replaced two major departmental secretaries, signaling a deliberate consolidation of power.

So Weimar was the COVID guy—why does that matter now, two years later?

Mimi

Because he's not just any bureaucrat. He ran the pandemic response when the state was under enormous pressure. That's the kind of person you either keep close or you distance yourself from, depending on how you want to be seen.

Mark

And Carroll wants to distance himself?

Mimi

Not necessarily. Carroll actually thanked him publicly. But the timing—replacing the top two secretaries within days—suggests Carroll is building his own team, not inheriting one.

Mark

Is Adamson a known quantity?

Mimi

She's been inside the department the whole time, so she knows the work. But she's also new to the top job, which means Carroll gets to shape how transport policy unfolds from here.

Mark

What's the real story underneath this?

Mimi

It's about control. New premiers don't trust inherited structures. They want people who answer to them, not to the previous regime.

Mark

And if Adamson stumbles?

Mimi

Then Carroll owns it. That's the trade-off when you remake the leadership this quickly.

  • A second high-profile public service exit in days signals that Premier Carroll's restructuring of Victoria's bureaucracy is deliberate, not incidental.
  • Weimar's departure carries symbolic weight — he was one of the state's most visible officials, having led the pandemic response and navigated the politically fraught Commonwealth Games cancellation.
  • The rapid replacement of both the Department of Premier and Cabinet secretary and now the transport secretary raises questions about whether Carroll is shifting policy direction or simply asserting new lines of authority.
  • Deputy secretary Fiona Adamson steps into the role immediately, keeping institutional knowledge intact while still marking a clear change in leadership.
  • Carroll's framing of both exits as orderly and worthy of acknowledgment suggests a careful effort to manage the optics of what is, in effect, a significant remaking of the senior public service.

In the quiet machinery of governance, new premiers often speak loudest through the appointments they make and the departures they accept. Jeroen Weimar, who guided Victoria through the turbulence of a pandemic and the complexity of a cancelled Commonwealth Games, has now stepped away from his role as transport secretary — a departure announced by Premier Ben Carroll just weeks into his tenure. It is a moment that belongs to a familiar arc in democratic life: the transition of power expressed not through legislation, but through the reshaping of the people who carry it out.

Jeroen Weimar is leaving his position as secretary of Victoria's Department of Transport and Planning, the latest in a series of senior public service changes under newly installed Premier Ben Carroll.

Weimar had held the transport portfolio since January 2025, but his tenure has come to an end. Carroll announced the departure on Thursday, acknowledging Weimar's contributions across the public sector — a nod that carries particular resonance given Weimar's prominent role as Victoria's COVID-19 pandemic commander and his stewardship of Commonwealth Games preparations before the event was cancelled.

The exit follows Carroll's earlier decision, within days of taking office, to replace Department of Premier and Cabinet secretary Jeremi Moule with Chris Barrett. Together, the two moves suggest a more comprehensive reshaping of the state's senior bureaucracy than a single personnel change might imply.

Fiona Adamson, currently deputy secretary of transport services within the same department, will step into the role from Friday. Her appointment keeps institutional knowledge close while still marking a shift in direction. Carroll highlighted her familiarity with the transport sector and framed her leadership as essential to delivering major infrastructure projects and driving reforms across planning, housing, and development.

The pattern is one common to new governments: consolidating authority by placing trusted figures in key positions. Whether Carroll's early moves signal a genuine change in policy or simply a reassertion of who holds the reins remains the question that will unfold in the months ahead.

Jeroen Weimar is stepping down as secretary of the Department of Transport and Planning, marking another significant leadership change in Victoria's public service under newly installed Premier Ben Carroll.

Weimar held the transport portfolio since January 2025, but his tenure has now ended. Carroll announced the departure on Thursday, describing Weimar's work across the department and the broader public sector as worthy of acknowledgment—a reference that carries particular weight given Weimar's high-profile role managing Victoria's COVID-19 response as the state's pandemic commander. He also oversaw preparations for the Commonwealth Games before the government ultimately decided to cancel the event.

The shift is part of a broader reshaping of Victoria's senior bureaucracy. Within days of becoming premier, Carroll had already replaced Jeremi Moule, the secretary of the Department of Premier and Cabinet, with Chris Barrett. Weimar's exit signals that the new leadership intends to remake the machinery of government more comprehensively than a single departmental swap might suggest.

Fiona Adamson will assume Weimar's role, beginning Friday. She has been serving as deputy secretary of transport services within the same department, meaning the transition keeps institutional knowledge in-house while still signaling a change in direction. Carroll's statement emphasized Adamson's deep familiarity with the transport sector and framed her appointment as essential to managing Victoria's transport network, delivering major infrastructure projects, and driving reforms in planning, housing, and development—the portfolio's core responsibilities.

Weimar's departure reflects a pattern common to new governments: the incoming leader consolidates power by installing trusted figures in key positions. For Carroll, these early moves suggest a deliberate strategy to reshape how the state's most senior public servants operate, whether through direct replacement or through the appointment of deputies to senior roles. The question now is whether these changes signal a shift in policy direction or simply a matter of establishing new lines of authority.

Carroll acknowledged Weimar's contribution to the department and across the Victorian public service, including throughout the pandemic, and wished him well for the future.
