The audit objectives were to establish whether Comcare took an effective leadership role in helping to manage the cost of occupational stress to the Commonwealth; and whether agency management of occupational stress was efficient and effective. The ANAO criteria for the audit focused on how well Comcare understood the impact of occupational stress across APS employment, and supported agencies in their management of the disability. They also dealt with how well agencies understood and measured the impact of stress, and planned for its prevention or minimisation.
