Investigation into Powerhouse Parramatta museum under way as stop-gap leader steps in

Powerhouse Parramatta CEO Steps Aside Amid Probe

Wanderstayfinder.com – The investigation into Powerhouse Parramatta museum has entered a sharper phase after chief executive Lisa Havilah stood aside from her post this week. The New South Wales government confirmed on Thursday that a formal misconduct inquiry into governance and procurement practices at the $915 million western Sydney institution will continue without Havilah in day-to-day leadership. Despite the upheaval, the museum remains on schedule to open its doors to the public on 7 November.

NSW arts minister John Graham outlined the decision at a budget estimates hearing on Monday. He explained that having two senior executives simultaneously steer the organisation and participate in a detailed investigative process had become “really starting to become unsustainable.” The remark underscored that the leadership change was driven by procedural conflict rather than a finding of wrongdoing.

“The idea that two of the senior executives were working through this process, this detailed process, and could also make sure that went smoothly was really starting to become unsustainable,” Graham told the committee.

Interim Leadership and the Road to Opening

Two appointments will bridge the gap until the inquiry concludes. Abbie Galvin, the NSW government architect, takes on the interim chief executive role, while Louise Herron — formerly chief executive of the Sydney Opera House — joins as a strategic advisor. Both begin their duties on Tuesday.

Melanie Hawyes, secretary of the department of creative industries, was careful to frame the transition as procedural. “These allegations that have come to light need to be tested, and that is what this investigation will do,” Hawyes said, urging stakeholders not to read a verdict into the leadership swap. Mark Wilsdon, the museum’s chief operating officer, is on leave and has been supplying substantial information to investigators, Graham added.

Why the Probe Matters for Western Sydney

Powerhouse Parramatta was conceived as a purpose-built home for science, technology, and design collections serving a region that has grown rapidly over two decades yet lacked a flagship cultural venue of national standing. Graham, who has overseen the project across multiple government cycles, has called it the “Opera House of the west.” That symbolic weight makes any governance disruption in the weeks before opening particularly conspicuous.

The formal misconduct investigation into Powerhouse Parramatta museum commenced in December of last year. It followed an earlier inquiry triggered by a whistleblower complaint in March 2025, which also prompted notification of the state’s anti-corruption commission. At the hearing, Graham disclosed that the procurement arrangements under examination fell below the roughly $6 million threshold at which a chief executive’s spending decisions require ministerial sign-off — placing the focus squarely on internal governance rather than on ministerial oversight failures.

Separately, a NSW Treasury review of the museum’s operational budget is proceeding on its own track, Hawyes clarified. Expenditure recorded under Havilah’s tenure includes a documentary chronicling the building’s construction (budgeted at a minimum of $1.7 million), a marketing programme totalling roughly $5 million, and $333,500 allocated to the interior design of on-site accommodation. Individually modest against the project’s $915 million capital envelope, these line items have drawn public attention given the timing of their approval.

Graham confirmed that members of the Powerhouse board, including chair of trustees David Borger, are not subjects of the current inquiry. The board’s role, he said, remains one of oversight and support while the interim leadership carries the institution through to opening.
