In the late 1980s Morse excavated a small limestone rockshelter known as Mandu Mandu at North-West Cape Western Australia as part of her post-graduate studies. Here she found perforated shell beads dating to c.30,000 which are the oldest examples of human adornment in Australia. It also demonstrated the antiquity of the exploitation of marine resources by Aboriginal people. In 2014 she excavated at Ganga Maya cave and Kariyarra Rockshelter, south of
Port Hedland, where she demonstrated continuous occupation of the northeast inland Pilbara, from 45,000 years ago to recent times. Morse was Director of Research at the
University of Western Australia, curator at the
Western Australian Museum and lecturer at the Centre for Archaeology at the University of Western Australia. Her fieldwork and research covered much of Western Australia, including the Ningaloo/Cape Range area, Perth metropolitan area, the Gascoyne, Murchison, Pilbara and Kimberley regions. Morse undertook consulting work as director of Eureka Archaeological Consulting. She was an advocate for high standards of research and meaningful outcomes from consulting practice as co-director of Big Island Research. ==Personal life and death==
