TPG Telecom group executive Wholesale, Dan Lloyd, was elected as the chairman and an executive search has begun to find a replacement for Althaus.

Ericsson Australia and New Zealand chief executive Emilio Romeo, Optus director Economic Regulation and Regulatory and Public Affairs, Luke van Hooft, and Motorola APAC Sales general manager Danny Adamopoulos were re-elected as directors.

The other directors are Dan Lloyd, Telstra External Affairs and Legal Network and Technology Regulation Principal Sustainability, Brian Miller, Nokia Oceania Market Unit head Anna Wills, Axicom chief executive Michael Riches, Samsung Electronics Government and Policy director Marc Dunn and ZTE Australia managing director Daniel Zhao.

"I am delighted to be re-elected chair of AMTA given the importance of the mobile industry to Australia," said Lloyd.

"While we are clearly disappointed to hear of Chris's intention to step down as CEO in early 2021, Chris has given 15 years of excellent service to the industry and leaves the industry and AMTA in a very strong position.

"Although Chris won't be leaving until next year, I would like to take the opportunity to formally thank him for his outstanding contribution. We will shortly be commencing a recruitment process for the challenging task of a replacement."

Althaus said: "It has been a privilege to represent AMTA's members and the broader sector through the rollout of three generations of mobile technology in Australia.

"It is a source of great satisfaction that as I prepare to conclude my role with AMTA, the mobile telecommunications industry is well placed to ensure Australians understand and appreciate the enormous potential that continues to be presented by the latest generation of mobile in this country.

"I have worked with, and met, a diverse and fascinating group of people and without question my industry colleagues have been a constant source of advice and friendship.

"Most particularly, the AMTA board members have provided invaluable wise counsel over the years. To the AMTA staff – you are the best and it has been my pleasure to work with you. I am very proud of AMTA, its role, standing, and contribution and this goes to reflect a great industry."
