City of Perth Acting CEO Peta Mabbs has resigned amid controversy over a $125,000 workplace culture review ordered by Lord Mayor Bruce Reynolds. In a report published on the council's website, Mabbs stated the review would be unlawful and a poor use of ratepayer funds.
Lord Mayor Reynolds is said to have given councillors only six minutes' notice before calling for the independent review, which was approved at a November 18 council meeting. The motion to establish a workplace culture committee was passed, but councillor Catherine Lezer plans to attempt to revoke the decision at the next council meeting in December.
Mabbs, who also serves as executive director of governance and strategy, wrote that no workplace culture issues were raised during a review of the CEO's performance in August. She revealed that complaints had been received about some councillors, with 10 complaints in 2025 regarding the behaviour of elected members.
Local Government Minister Hannah Beazley expressed concern and flagged possible intervention. The council confirmed Mabbs' resignation on Wednesday afternoon, but no reason was given. Mabbs had been acting for CEO Michelle Reynolds, who took pre-approved personal leave on November 14.
