In 1981, Topsy and Walter went to Uluṟu and set up a tent at the base of Uluṟu. From there they sold their " works to tourists for over two weeks. They did this trip with other artists from Amaṯa, including Pulya Taylor and Tony Tjamiwa, and their friends Peter Yates and Pat D'Arango. In 1983, this group travelled around to artist communities in the Aṉangu Pitjantjatjara Yankunytjatjara Lands. This was to discuss the idea of setting up a new craft centre at Uluṟu that would sell artworks from around the region to tourists. The couple moved to Muṯitjulu so that they could help set up Maṟuku Arts. Topsy and Water were some of the first artists for the centre, and worked together closely until Walter's death in 2004. Topsy is still a member of the organisation's Governing Committee.
