So sad to see this story in the news. My experience working for the department (10 years ago) was a positive one, though I understand how project implementations like these can have such negative outcomes for mental health. No-one should feel that suicide is their only recourse in times of trouble. If you or anyone you know needs help don't hesitate to make a call. In Australia Lifeline crisis support can be reached on 131114.
