The Australian Competition and Consumer Commission (ACCC) has appointed Sarah Proudfoot as its new chief executive officer, after Scott Gregson departed to take up the role of CEO at the Australian Securities and Investments Commission.
Proudfoot has been acting in the role since February, and has been selected to take on the position permanently following an extensive external recruitment process.
“One of the many things I’ve loved in my time at the ACCC is the fact our work makes a difference to people’s lives every day,” said Proudfoot.
“It is a significant responsibility and privilege to take on the role of CEO and to work with Commissioners and our talented, dedicated team in the interests of consumers and protecting competition across our economy.”
Since joining the ACCC/AER’s Infocentre in 2005, Proudfoot has held a range of senior roles in the agency, including executive general manager of the ACCC Infrastructure Division between 2020 and 2024 with oversight of the ACCC’s work across telecommunications, rail, ports, airports, electricity and gas, as well as the 2023 Childcare Inquiry.
She was appointed executive general manager of the ACCC’s National Anti-Scam Centre in August 2024 and has been acting chief executive since February 2025.
ACCC chair, Gina Cass-Gottlieb, said Proudfoot has consistently demonstrated ability as an outstanding strategic leader with personal drive, credibility and integrity, and a strong commitment to public service throughout her career.
“I am confident that with Sarah’s contribution as CEO leading our capable people, our agency will continue to deliver important outcomes for the Australian economy and community,” said Cass-Gottlieb.
The appointment comes as the ACCC prepares to take on new responsibilities, thanks to the Treasury Laws Amendment (Mergers and Acquisitions Reform) Bill 2024, which will come into effect on 1 January 2026. The bill was introduced to Parliament in October 2024, aiming to provide fit for purpose tools targeted at identifying and preventing anti-competitive mergers for the ACCC, and was passed in November.
