The Australian Civil Aviation Safety Authority's aviation medicine section has not published any relevant guidelines for DAME's since the issue by BEA of the report into the GermanWings suicide.
Their website has this general information -
Depression and aviation safety fact sheet
While we all feel sad, moody or low from time to time, some people experience these feelings intensely, for long periods of time (weeks, months or even years) and sometimes without any apparent reason. Depression is more than just a low mood - it's a serious illness that has an impact on both physical and mental health.
Research suggests that continuing difficulties - long-term unemployment, living in an abusive or uncaring relationship, long-term isolation or loneliness, prolonged exposure to stress at work - are more likely to cause depression than recent life stresses. However, recent events (such as losing a job) or a combination of events can ‘trigger' depression in people who are already at risk because of past bad experiences or personal factors
Depression affects how people feel about themselves. They may lose interest in work, hobbies and doing things they normally enjoy. They may lack energy, have difficulty sleeping or sleep more than usual. Some people feel irritable and some find it hard to concentrate. Depression makes life more difficult to manage from day to day.
On average, one in six people - one in five women and one in eight men - will experience depression at some stage of their lives. There are different types of depression. Symptoms can range from minor (but still disabling) through to very severe.
