The Australian Computer Society (ACS) has announced a change in leadership, with its CEO stepping down and a former president appointed to lead the organisation on an interim basis.

In a message to staff, ACS president Beau Tydd said the organisation's Management Committee (MC) had endorsed a leadership transition and confirmed that chief executive Josh Griggs had commenced a transition out of the role and would no longer be actively involved in ACS matters.

On behalf of the society, Tydd thanked Josh for his contribution to ACS and the Australian ICT Industry.

ACS’s Management Committee has appointed Dr Prins Ralston as acting chief executive officer, effective Tuesday 10 March.

The committee said Ralston brings extensive leadership experience across the public, private and not-for-profit sectors.

He has served as a chief executive for 18 years, most recently leading Townsville City Council, where he oversaw organisational transformation within an operation with an annual budget approaching $1 billion.

Ralston’s background spans engineering, information technology and communications, alongside qualifications in accounting and law and a doctorate in juridical science.

Earlier in his career he spent seven years as a partner at national and top-tier law firms specialising in capital markets and governance.

ACS said Ralston also has a long association with the society. He is a Fellow of the organisation, a former ACS president and has held senior leadership roles advancing ICT professionalism both nationally and internationally.

MC said it would continue communicating with staff during the transition and that the acting chief executive would outline priorities and next steps in due course.
