A fast-moving grass fire ripped through 40 hectares of grassland, forcing stock evacuations and threatening several homes in the Yass Valley on Wednesday.
The fire started just after 4.20pm near houses at Wallaroo. At one stage, the fire was threatening up to 10 homes.
Rural Fire Service volunteers from NSW and the ACT rushed to the scene, working quickly to contain the flames. Two helicopters doused the flames from above, while more than 20 fire units worked on the ground.
A bulldozer was used to create containment lines, and the fire was brought under control by 5.10pm.
No homes were destroyed, although some sheds and adjacent buildings were damaged. The fire also damaged a vineyard.
