Goulburn River Seymour - Scarred Tree

This Aboriginal scarred tree is next to the old Hume Highway and the bridge over the Goulburn River at Seymour. It has been used as a local notice board and bears the modern scars of numerous nails and tacks. I wonder if scars served some similar purpose for Aborigines, not just the carved trees with special marks, but the incidental ones that were used for functional bark objects.
