FIRES contain to burn in the Mallee region.
Blazes in Wyperfield National Park, Big Desert Wilderness Park and Bronzewing Flora and Fauna Reserve have destroyed 80,000 hectares of grassland.
Fire crews were first alerted to a fire in the Wyperfield National Park on January 14, with Country Fire Authorities believing the blazes could take several weeks to contain.
A CFA media spokesman said the Wyperfield blaze had burnt through more than 42,000 hectares of grassland with tankers, slip on vehicles and aircraft on scene.
The CFA is warning people in the Mallee region to stay informed.
The media spokesman said there is currently no threat to communities but people should be cautious.
He said fire conditions were quiet on Sunday night due to light winds and moisture in the air.
He said crews were working to contain the fire to public land.
A number of firies from central Victoria have travelled to the area to offer assistance.
