The world's timber engineering leaders recently convened in Oslo for the bi-annual World Conference on Timber Engineering (WCTE), and the Australian presence was stronger than ever, with forty-three attendees out of 850.
In a remarkable display of determination, two of Australia's most esteemed timber engineering educators, Lisa Ottenhaus and Jon Shanks, are gearing up for an extraordinary challenge this September.
