Farmers have been rejoicing after rain finally fell across New South Wales over the weekend, offering a much-needed reprieve from a drought that has ravaged the region for years.

Some took to social media to show off their impromptu rain dances.

Bourke, in northern NSW, saw 94mm of rain over the entire weekend. According to local media, 100mm fell in some parts of the state.

While, the long-range forecast for the summer indicates that there will be below-average rainfall, the weekend's precipitation allows farmers to replenish reservoirs.

More rains will be needed though, to break a drought that has gripped a swathe of Australia's southeast for three years, turning pastures brown and forcing ranchers to buy expensive feed grains to keep their herds alive.
