  • The Gippsland Lakes

  • The array of streams, especially the wild rivers, including the iconic Snowy River and Victoria’s biggest unregulated stream, the Mitchell River;
  • Long coastal reach with undeveloped estuaries, ocean beaches and spectacular headlands;

Mountains and forests, which provide great scenery, clean air, clean water, recreational opportunity and forestry products;
  • Scenic and productive farming lands, especially in the river valleys; and
  • The living wealth in the form of native plants and animals, some of which occur only in this region.

Program Highlights

The region’s natural resource management priorities have been dominated by two factors:
  1. The regular incidence of drought, fires and major floods; and
  2. The large expanse of largely intact natural landscapes.

East Gippsland has encountered major droughts in 1997/98 and 2002/07 which have given cause to the largest bushfires in European history in 2002/03
2003 Eastern Victorian alpine bushfires
The Eastern Victorian alpine bushfires, also known as the Great Divide Fire Complex, started with eighty seven fires that were started by lightning in the north east of Victoria on 8 January 2003...

 and 2006/07. Each major drought has also been broken by major floods in 1998 and 2007. Major recovery works have been undertaken in response to all these natural events.

East Gippsland CMA have the largest number of high value rivers including the Mitchell

In a recent survey of the area, over 70% of those surveyed considered the Lakes their most valuable natural asset.
The Great Alpine and Divide Fires of 02/03 and 06/07 created extensive burnt areas in the Mitchell, Tambo, Nicholson and Snowy River catchments and together with recent floods will cause water quality and supply problems for many years.
