The state government has committed an extra $355 million to help farmers and rural communities struggling with the drought.
The money is in addition to the almost $400 million announced during the March election campaign.
Agriculture minister Adam Marshall said it brought the government's total support bill to $1.8 billion.
"The impact of this drought is being felt everywhere and by everyone right across country NSW," Mr Marshall said.
"It's hurting our farmers, but also our local businesses, schools and people's overall mental health - there's been no decent rain and cash is also running dry.

"(This) new drought assistance package recognises the challenges on the land and the fact that 97 per cent of the State is still in the grip of drought or intense drought conditions.
"The best drought support is rain and lots of it, but while no government can make it rain, this new and additional funding is the next best thing.
"While droughts are a natural part of doing business on the land, this drought is unique and I'm confident this package will help alleviate the some of the burden associated with one of the worst droughts in living memory," Mr Marshall said.
The announcement will be fully funded in next week's state budget and start on July 1.
Mr Marshall said that more than 140,000 farmers across the state had already benefited from the government's drought support package, "through the various fee waivers, subsidies, grants and no interest loans".
