Their work became synonymous with campaigns to protect Tasmania's natural heritage. They shared many things, including a bond that was more like that of father and son.

Both died in the wilderness, doing what they loved, and left a legacy in extraordinary images. Their philosophy was simple and remarkably effective - if people could see the beauty of Australia's wild places then they might be moved to save them.
