Figures released by the NSW Department of Primary Industries on Tuesday showed that 6284 had been euthanised or confirmed dead.

And that number was expected to rise.

The Rural has been contacted by a number of landholders who reported losses and confirmed they had to shoot animals which were injured during the fires.

Large scale tracts of fencing and infrastructure were lost too.

A total of 5298 stock were lost from south-east NSW since Christmas.

NSW Farmers president James Jackson said this figure was likely to rise as assessment teams and farmers access the fire grounds.

"The NSW Farmers Dairy committee is reporting that fodder and fuel is starting to make its way to dairy farms on the South Coast, which will be urgently needed," Mr Jackson said.

"We also need to be mindful that the impact on horticultural operations will be extensive as well.

The fires have impacted a wide variety of agricultural enterprises in NSW, from oyster sheds on the South Coast to apple orchards in Batlow and Bilpin and honey producers."

NSW Farmers is working with government agencies and rural charities including Rural Aid to start to plan the transition from emergency assistance to recovery support.

"As always, farmers are out there helping their fellow farmers with fodder donations and community organisations are doing all they can to support everyone.

But farmers do require immediate and ongoing assistance to keep livestock alive with water and feed supplies," Mr Jackson said. "Our priority is to work closely with the DPI and Local Land Services to ensure that farmers are getting the ongoing assistance they need."

Farmers can report stock losses and infrastructure damage by calling the Agricultural and Animal Services Hotline on 1800 814 647.

People without phone access are urged to send a direct message via the NSW DPI Facebook page.
