He remains in the Royal Hobart Hospital.

The man was employed by the City of Launceston council. 

On Wednesday, the council’s general manager Michael Stretton released a statement. 

“There is an ongoing Work Safe Tasmania investigation into the incident at the Cataract Gorge on Monday involving two City of Launceston officers,” he said.

“Given that, it is not appropriate for the council to comment at this time with respect to the individuals and families involved.”

City of Launceston council acknowledge the incident on Monday.

“Our thoughts and best wishes are with them for a speedy recovery,” Mr Stretton said. 

The 51-year-old man was one of two employees working on the East-side of Launceston’s Cataract Gorge. 

The pair were inspecting a drain unrelated to the tree. 

It is understood the tree collapsed without warning falling out from the root structure.

The other worker present was treated for shock and minor injuries only.

Work Safe Tasmania also attended the scene and are investigating.

Tasmania Police and other emergency services were called to the scene about 1.45pm on December 3. 

The name of the injured worker is yet to be publicly released.

A number of other trees fell during winds on Monday, but no other injuries were reported.
