Planning for NSW Alpine Resorts

Alpine resort development assessments are governed by the State Environmental Planning Policy (Kosciuszko National Park-Alpine Resorts) 2007 (the Alpine SEPP). The Alpine SEPP aims to protect the natural and cultural heritage of land within the Alpine resorts and to encourage environmentally sustainable development.


The NSW alpine resort areas include Thredbo, Perisher Range (including Bullocks Flat), Mount Selwyn, Charlotte Pass, Kosciusko Mountain Retreat, Ski Rider and Sponars Chalet, located within the unique and environmentally-significant setting of Kosciuszko National Park.


The resorts provide a range of snow-based recreational activities during winter, along with hiking, mountain-biking, riding and fishing during the warmer months.  The resorts are important to NSW due to their economic and social contribution.


Key requirements of the Alpine SEPP include:

  • All development to be subject to the assessment of environmental impacts to protect the unique alpine environment
  • Geotechnical and land stability issues associated with construction in steep alpine environments to be rigorously assessed (see Geotechnical PolicyGeotechnical Forms and Geotechnical Maps)
  • All major development proposals to be advertised
  • Development proposals to be referred to the NSW Office of Environment and Heritage for comment and to be authorised under the National Parks and Wildlife Act 1974.

The following maps show the land to which the policy applies. Please note some of these files are large (up to 24 MB) so may take time to download.

Lodging a development application

Under the Alpine SEPP, the Minister for Planning is the consent authority for development. 


To undertake development within the NSW alpine resort areas proponents need to lodge a development application with the Department. It is recommended that proponents contact the Alpine Resorts Team and any other relevant agencies to discuss their proposal.
