The National Parks and Wildlife Service (NPWS) is a directorate of the New South Wales Department of Planning and Environment and responsible for managing more than 890 national parks and reserves, covering over 7.5 million hectares of land across the state of New South Wales, Australia.

[3] Lewis also established a charity, the National Parks Foundation, to assist the NPWS in raising funds for conservation.

[11] Nearly 900 protected areas of a variety of types have been declared in New South Wales under the National Parks and Wildlife Act 1974, most of which the NPWS has the responsibility to manage.

Covering over 70,000 square kilometres (7,000,000 ha),[12] these range from national parks where the NPWS is tasked with conserving biodiversity and protecting ecological integrity to other less restrictive categories of parks and reserves where more intensive human activity must be balanced against maintaining natural and cultural values.

[14] The NPWS also administers fire management strategies for the land it manages in order to limit risks from bushfires,[15] such as by conducting hazard reduction burns in collaboration with other state agencies such as the New South Wales Rural Fire Service.
