Morauta taught at UPNG from 1970 to 1978. From 1978 to 1983 she was a senior research fellow at the
Papua New Guinea Institute for Applied Social and Economic Research (IASER) in PNG's capital,
Port Moresby. Her work there was focussed on transfers between rural and urban areas, transfers between households in a rural area of high outmigration, the emergence of permanent urban residents, and interhousehold transfers in poorer urban areas. Morauta returned in 1985 to teach at UPNG and at the end of 1986 she migrated from Papua New Guinea to Australia. In 1987 Morauta joined the
Australian Public Service in Canberra. After working in the Australian International Development Assistance Bureau (1987 - 1990) and the Department of Finance (1990 - 1994), Morauta moved to the Department of Health and Ageing. While at that department, Morauta occupied a number of first assistant secretary roles, including portfolio strategies, health benefits, health access and financing and acute care. She chaired several interdepartmental and inter-governmental committees, including the Jurisdictional Blood Committee (JBC). In 2004 she was seconded to the Department of the Prime Minister and Cabinet to work on a health task force to examine the interface between state and federal health programs. In 2005 she moved to that department as a deputy secretary in charge of social policy, health and indigenous affairs, where she stayed until 2008. In 2008 and 2009 Morauta, then on
secondment to the Department of Human Services in Victoria, was the project director for the National Registration and Accreditation Implementation Project. This project put in place the basic elements of the new national registration scheme for health practitioners, which replaced the previous state-based systems and commenced on 1 July 2010. Following her retirement from the public service, Morauta was appointed as a lay member to the
Australian Capital Territory (ACT) Human Research Ethics Committee, in January 2010. From 2014 to 2017 she was the Chair of that committee. Morauta also served as a director of the Lowitja Institute, the National Institute for Aboriginal and
Torres Strait Islander Health Research from 2010 to 2013. ==Awards and honours==
