Bushfire-hit communities in NSW's central west can use government funding to help rebuild their properties.
The disaster relief will be available to residents, farmers and councils after fires razed more than 40,000 hectares of land during the state's hottest March on record.
Federal Emergency Management Minister Murray Watt says it's a stressful time for affected residents and farmers.
"I urge those defending their farms, livestock and properties to please be vigilant, stay up-to-date with advice and be very careful with the use of fire," he said on Tuesday.
The community of Forbes is in mourning after 75-year-old farmer Viv Coady was killed during a hazard reduction burn on his property on Saturday.
The joint federal and NSW government support will include money for repairing damaged property, business loans and funding for councils to restore public assets.
The amount of support individuals will be able to access will vary depending on how much damage they suffered and will be means tested.
The package will be available to residents in the local government areas of Bathurst, Bogan, Brewarrina, Coonamble, Dubbo, Mid-Western, Walgett and Warren.
NSW Emergency Services Minister Steph Cooke says the NSW and Australian governments are working together to help with additional areas expected to be disaster declared shortly following more recent fires.
After the state's coolest summer in 11 years, NSW is on track for its hottest March on record.
The Bureau of Meteorology has warned increased fuel loads and drier weather will raise the risk of catastrophic east coast fires next summer.
