The Department of Environment, Parks and Water Security (DEPWS) was established by the Northern Territory (NT) Government on 8 September 2020.

This new department combined the functions of the previous Department of Environment and Natural Resources and the Parks and Wildlife Commission from the former Department of Tourism, Sport and Culture (DTSC).

The government established the department to combine many of the key functions that foster and protect the environment and natural resources in the NT.

This includes water, land resource management, environmental issues and the parks and wildlife functions.
