SUNKEN TREASURE

Hunt for sunken treasure: 

Harvesting Tasmania's forests submerged in man-made dams

Underneath the inky tannin-stained waters hides sunken treasure that one innovative company is bringing to the surface.

Sustainable Forestry Solutions managing director Andrew Morgan said the project had been in planning for a long time.

"It's pretty surreal, it's been a baby of ours for three years and to take it from paper drawings to actually standing at Lake Pieman and pulling out trees, it's pretty monumental," he said.

The skeletons of giant eucalypts poke through the 50-kilometre long lake, hinting at a wealth of forests underneath.

Incredibly Mr Morgan's company found a way to harvest underwater trees. 

They looked overseas at similar underwater harvesting projects.

"What we saw was that you can do this, it is possible," he said.

"We then went and approached Hydro Tasmania and the Tasmanian Government about a feasibility study and they funded us.

"We went out and proved the wood was sound, that there was technology out there to extract the timber safely, the rest is history.”
