Mr Conaghan said State and Territory governments are primarily responsible for responding to natural disasters, including the landslide at Devils Nook, six kilometres east of Bellbrook.

The landslip started about 85 metres above the roadway and has taken out tonnes of rock and debris.

Kempsey Shire Council engaged specialist geotech engineers to inspect the site leading to the road's closure on Monday.

"Should it be required, the Federal Government has made it easier for States and Territories to request Federal assistance including support from the ADF," Mr Conaghan said.

"States and Territories will need to consider factors including their own capabilities and that of local contractors before making such a request.

"The Federal Government stands ready to provide assistance if required."

Mr Conaghan visited the Bellbrook landslip site today along with Kempsey Shire Council mayor Liz Campbell and general manager Craig Milburn.

It was expected that a SES helicopter would water-bomb the site during Friday to help remove potentially dangerous debris from the site.

The slip is still moving and dangerous while there are several trees either balanced or still at risk of slipping.

Kempsey Shire Council has engaged specialist engineers who will plan the most appropriate method for clearing and stabilising the site. However the site remains dangerous with unstable rocks and trees.

This landslip has impacted around 300 residents of Bellbrook and surrounding area. Kempsey Shire Council has organised with the SES for emergency supply drops each Wednesday and Friday.

Some 100kg of urgent supplies of non-perishable goods or medications was air-lifted earlier in the week. These items were delivered to the Elbow Street Recovery Hub and distributed through the Bellbrook Hotel.
