Missing grandmother found after spending two nights lost in bushland south-east of Perth

A missing 77-year-old woman has walked out of bushland south-east of Perth, two days after she was last seen.

Alice Smallhorn went missing from her Kiln Road home about 6pm Saturday, WA Police said.

About 9am today, a resident at a nearby property in Barge Drive, Byford, saw her walking out of bushland and recognised her.

Ms Smallhorn appears to be in good health after spending two nights lost, police said.

Emergency services had launched a large-scale search for her yesterday, with 30 SES volunteers scouring the surrounding area.

Today, six teams returned to resume the search shortly before Ms Smallhorn was found.
