Charles meets emergency service workers

Prince Charles has arrived at one of Australia's richest banks for a series of talks with firefighters, police and Red Cross nurses about mental health after disasters like the Lindt cafe siege, shootings and bushfires.

Crowds gathered outside a building in the Sydney CBD glimpsed the prince, wearing a grey suit with grey silk handkerchief and pale yellow and black diagonally striped tie, when he arrived.

He was greeted on the top floor of the Macquarie Group building by former Australian defence force chief, Sir Angus Houston, who is patron of the private event the Prince is taking part in - the Skills for Psychological Recovery Foundation Roundtable.

Also greeting the prince were the CEO of the Prince's Charities Australia Janine Kirk and Professor David Forbes, director of the Phoenix Australia institute for Post Traumatic Mental Health.

Prince Charles will also meet 22 professors of psychology and psychiatry from the UK, US, Canada and around Australia before moving into round table discussions with police and emergency service men and women.

Among the topics the prince will discuss is improving outcomes for survivors of disasters.

The groups talking with the prince include the Blue Mountain's Recovery Network, the Royal Flying Doctor Service and former Australian soldiers, and naval and airforce men and women.
