Heith Mackay-Cruise will step down as chairman and retire as a director of the Southern Cross Media Group on 30 June. He took over from Kerry Stokes on 20 February.
Mackay-Cruise confirmed he would be stepping down in an ASX announcement. “After almost six years on the Board and more than two years as chairman of Southern Cross Media Group, I am proud to have overseen the restructuring of the Company, combining with Seven West Media to create the largest commercial media platform that services all of Australia.
“With the appointment of Rohan Lund as our new managing director and chief executive officer, I believe SCA is well-positioned for the future, and it is the right time for me to move on to other challenges.”
Teresa Dyson as been appointed by the board to take over from 1 July. She becomes the third chair in six months.
Dyson is an experienced company director who served on the Seven West Media Board for over eight years before transitioning to the SCA Board earlier this year. Over her career, Dyson has led strategic decision making in business and organisational structuring across the financial services, transport, health, energy and resources sectors, as well as infrastructure projects, following over 20 years practising as a lawyer.
“The Board wishes to gratefully acknowledge Heith’s significant contribution as a director over the past six years, and particularly in recent years as Chairman, in building SCA’s nation-wide reach and accelerating the integration of our television, audio, digital and publishing assets,” said Dyson.
“I am looking forward to working closely with Heith, Rohan and my fellow directors over the upcoming transition period and as we continue to drive our performance, deliver the full value and synergies of our operations and diverse content platforms, and carefully manage succession on the Board.”
As previously announced by SCA to ASX in September 2025, Mr Ido Leffler will also retire as a Director on 30 June 2026. Ms Dyson said: “On behalf of the Board, I sincerely thank Ido for his service as a Director over six years, during which time he has sharpened our digital focus, and helped develop and guide SCA’s strategic growth agenda.”
The news follows as one of SCA’s major investors Sandon Capital announced its intentions to remove Mackay-Cruise, as well as Ido Leffler and Marina Go as directors of the company.
