At Territory level, the electoral division of Katherine covers the town and its suburbs and elects one member to the Northern Territory Legislative Assembly. Jo Hersey won the election in 2020 for the CLP, ousting Labor party member Sandra Nelson . Many Northern Territory Government departments have offices in Katherine with most of these housed in the Government Centre building in First Street, which allows the community to access services such as motor vehicle registration and public health clinics, family and community services and public housing.[18] There is also a courthouse located next door which regularly hears matters before the Northern Territory Magistrates Court within the chambers.
