The nature conservation lobby in New South Wales is ramping up its campaign against the commercialisation of national parks.

They say the state Government is currently considering legislative changes, in response to a report from the Tourism Taskforce.

The Taskforce recommended increasing accommodation options for visitors inside national parks, including the construction of new buildings.

But green organisations say that this would threaten biodiversity in the parks.

They also say that if the Government wants to increase tourism in the parks, there are more sustainable models available.
