Rural and remote Australian mental health services have been in a state of crisis, according to the chief executive of the Royal Flying Doctor Service.

Doctors have been finding themselves overwhelmed by the amount of psychological support they need to provide to their patients, as major disparities between country and city services still exist, despite numerous government reviews designed to address the problem.

Suicide rates in rural areas are 4% higher than those in major cities, and in remote areas, the rate is almost double.

If you or anyone you know is struggling with mental health, call Lifeline on 13 11 14.
