Praise as Vic police minister seeks help

Victoria's police minister has been praised from both sides of politics for admitting that mental health issues caused by his work have forced him to take extended leave and seek counselling.

Wade Noonan stunned Spring Street on Monday, announcing he would take a three-month break to cope with trauma from the "unspeakable crimes and traumatic events" that were an everyday part of his role.

"The accumulation of these experiences has taken an unexpected toll," Mr Noonan said in a statement.

Premier Daniel Andrews backed Mr Noonan.

"He has made a courageous decision that is in the best interests of his health and his family, and I commend him for it," Mr Andrews said in a statement.

Opposition Leader Matthew Guy also offered support.

"We wish Wade and his family all the best and look forward to seeing him back at parliament soon," he said in a statement.

Victoria Police chief Graham Ashton said police understand well "the impact of mental health in the emergency services sector", wishing Mr Noonan and his family well.

Police Association secretary Ron Iddles said Mr Noonan was a "very good police minister" who was willing to consult the union, and meet rank-and-file members and workplace delegates.

"We very much look forward to working with Mr Noonan in the future," he said.

Beyondblue chairman and former Victorian premier Jeff Kennett congratulated Mr Noonan for seeking help and both leaders for their support.

"Today an individual's health has been given a greater priority than the politics of the day," Mr Kennett said.

Robin Scott will act as police and corrections minister until Mr Noonan returns, while Footscray MLA Marsha Thomson will look after his constituents in the neighbouring Williamstown seat.

Mr Noonan, 44, a married father of two, followed retiring premier Steve Bracks into Williamstown in 2007.

His political career began in 1996 when he joined the Shop Distributive and Allied Employees Association as an organiser.

Mr Noonan moved to the Transport Workers Union in 2002, rising to federal secretary before entering parliament.

He became opposition police and emergency services spokesman in December 2013, 11 months before the Andrews government took office.
