The Australian Computer Society is governed by a national Management Committee.  This committee is assisted by a National Congress, eight State and Territory Branch Executive Committees, and three expert advisory boards - the Member Advisory Board, the Profession Advisory Board, and the Technical Advisory Board.

All three Boards provide strategy advice within their areas of expertise to Management Committee via their Vice Presidents.

One of the key strengths of the ACS is the collective knowledge and skills of its members, and the expert advisory boards are the framework for optimising this expertise.

The ACS Management Committee controls and manages the Society, within the bounds set by the Associations Incorporations Act (ACT) and the Society’s Objects, Rules and National Regulations.

The Management Committee consists of the National Office Bearers (President, three Vice Presidents, Immediate Past President, National Treasurer) as well as the Chief Executive Officer and four National Congressional Representatives.
