Almost a week after Rocky Eiao wandered off into the harsh and unforgiving bush in outback NSW, a woman's body has been found.

Police believe the body is that of Ms Eiao, 25, who walked off into rugged terrain at Girilambone, in north-west NSW, last Friday.

One of the dogs that had stayed with Ms Eiao was found dead near the body.

Ms Eiao, who worked as a sheep shearer, had set off from her hometown of Nyngan, north-west of Dubbo, with her boyfriend and another friend for a drive through the bush.
