A plywood manufacturer in Adelaide's south-west has gone into administration.
The State Opposition says 47 people have lost their jobs as a result of the closure of Brown Wood Panels at Camden Park.
The company made plywood products for the construction industry and had distributors interstate.
It was founded after World War Two at Mile End and moved to its current premises in 1972.
The Opposition's forestry spokesman Adrian Pederick says high timber prices and uncertainty in the milling industry, caused by the forward sale of harvesting rights in South East plantation forests, have led to the closure.
"I understood Brown Wood Panels to be quite a successful firm," he said.
"I was actually surprised to see it's shut recently because it'd been sourcing timber from the Hills forest and also the Wirrabara forest area up near Jamestown, so I thought it was quite a successful business.
"The forward sale of the rotations in the South East has reverberated right throughout the state's millers.
They're uncertain of the future of the milling industry in this state because of the sale." A company representative has directed enquiries to the administrators Clifton Hall.
