NSW National Parks and Wildlife Service (NPWS) Hunter Central Coast director, Kylie Yeend said the 3.2 kilometre stretch of Mungo Brush Road was relocated due to constant westward shifting of Dark Point sand dune.

"We've completed the project right on target," Ms Yeend said.

"The Christmas holiday season is upon us, our new roads and carparks are ready for locals and visitors.

"We've saved this important road from being swallowed by the mobile sand dunes by relocating it.

"Its new position also protects the dune complex, which is a culturally significant, declared Aboriginal Place.

"Parking for buses and long-wheel base vehicles in the upgraded Dark Point carpark is now available.

"The sand dunes can be accessed by the walking track which starts near the car park."

In a separate project, a small section of the nearby Mungo walking track - stretching from Robinsons Crossing to Brambles Green - will re-open early next year once maintenance and rehabilitation works are completed.

The previous road ran alongside Dark Point Dunes, a 250-hectare mobile sand dune complex with cultural significance to the Worimi people.

Each year this expansive dune spreads 3.3 to 5.9 metres in a westward direction.

The new sealed, dual lane road runs west alongside the former Mungo Brush Road, linking southern Myall Lakes National Park with Tea Gardens, Hawks Nest and Bulahdelah.

The old section of road has been rehabilitated back into the National Park.

The re-establishment of the roadside vegetation will continue with landscaping maintenance works into 2020.

"The work was part of the NSW Government's commitment to maintaining access to the popular Mungo Brush Road for local residents and visitors.

"It's been delivered on time and has made access to the park easier for local residents and visitors alike."
