Actor Tasma Walton is trying to back away from her involvement in a native title dispute, with her lawyer saying she fears for her family and her livelihood after her role in the Federal Court case became public. Walton was the first witness for the Bunurong group, which is challenging a native title application submitted by the Boon Wurrung Land and Sea Council covering 13,000 square kilometres along Victoria’s coast from Werribee to Wilsons Promontory.
