Mr Murray, an avid bushwalker, was last seen at home on Friday, March 20.

He left home in his blue 1996 Daihatsu Charade, with registration EP 2014. He had taken his sleeping bag and wet weather gear.

Mr Murray often went away for several nights to various parks for bushwalking, but generally maintained phone contact with family.

On this occasion there has been no contact with his family or friends since March 20 and his phone is not emitting a signal.

While Mr Murray is fit and healthy, he does suffer from diabetes and requires insulin.

Police are extremely concerned about Mr Murray given his medical condition and the fact that he has never been away for such an extended period.

Recent poor weather is also a concern.

Police and Mr Murray’s friends have been searching remote roads and car parks at walking trails to try and locate his vehicle and believe the car is critical to locating him.

Mr Murray had mentioned a variety of walks in recent months, including Adamson’s Peak, the Wellington Ranges, Cradle Mountain and the Tasman Peninsula.

Parks and Wildlife officers have been advised, but police think a member of the public may well see or have seen Mr Murray’s Daihatsu and if so they are urged to contact police immediately.

A picture of Mr Murray and a blue Charade are on the Police Facebook Page.
