Police continue to search for missing 76-year-old experienced bushwalker, James ‘Jim’ McLean who is overdue from a one month trek in the state’s far south-west.

The current search area is concentrating around the three main tracks that stretch between Melaleuca and the start of the Huon Track near the Picton River at Tahune.

Yesterday morning, the Westpac Rescue Helicopter assisted with positioning teams of Search and Rescue and SES volunteer wilderness walkers into the area. The searchers camped overnight and continued their track search today.

The four search teams are expected to meet up later today at which point they will be extracted by the Westpac Rescue Helicopter and debriefed.

The outcome of the two-day land search will determine future search strategies, methods, designated search area/s and survivability modelling.

There is unconfirmed information that Mr McLean, who has not been sighted since Monday 12 November, might have placed food packages at strategic locations within previous walks and stated he had enough provisions for 40 days.

Anyone who may have come across Mr McLean either during the walk or who may have seen him since is asked to contact Tasmania Police on 131 444.
