Legal action in the Land and Environment Court has led to a temporary halt to logging in a state forest that could form part of the proposed Great Koala National Park.

Alan Oshlack, an agent acting on behalf of Gumbaynggirr elder Michael "Micklo" Jarrett, went before the court with a notice of motion aiming to permanently stop logging in the state forest.

In the Land and Environment Court, a person can be represented by a non-legal agent in certain cases.

The undertaking allows haulage and the removal of already-felled trees to continue.

A NSW Forestry Corporation spokesperson said operations in Newry State Forest had been "conducted in line with the strict conditions regulating native forestry in NSW, which have been developed with the input of expert scientific panels to protect and maintain wildlife habitat, forest flora, water quality and biodiversity across the landscape".

He said the area contained sites of cultural significance to the Gumbaynggirr people.
