Victoria Police is grappling with the suicides of two officers in a week, as it awaits a high-level review of mental health issues within the force that is expected to recommend an overhaul of support services.

As Chief Commissioner Graham Ashton described the challenge of mental health issues among police as "one of the most important issues" he had to face, the families of the two officers were mourning the sudden losses.

In 41 days this year, two officers and a police employee have taken their lives. It has been almost 10 years since a Victoria Police officer died on duty, according to the Police Association honour roll.

The first officer who died this week was from Echuca police station, but ended his life at a house in Tocumwal, a small town in NSW about 110 kilometres to the north-east.
