By Raquel Mustillo SOUTH Australia’s peak timber processors association has questioned why log exports out of the Port of Portland have continued amid a nationwide shortage of structural timber.

Demand for sawlog – which is the wood that can be processed into beams, planks or components of timber frames – has skyrocketed across the globe, with the finished product fetching prices 350pc higher than the same time last year in some international markets.
