Two women and a young girl have been flown to Perth after a serious crash in the Great Southern.
The three were travelling along Great Southern Highway last night when their car came off the road and hit a tree just outside of Katanning.
A St John Ambulance spokesman said they were initially taken to Katanning Hospital with serious injuries, before the girl and one of the women were flown to Perth this morning.
The child was taken to Princess Margaret Hospital and the woman to Royal Perth, both in a serious condition.
He said the second woman was expected to be flown to Perth this morning.
