Three Vic woman stuck on cliff face

Emergency services will pull three women trapped on a cliff face in Victoria to safety after they became stuck and called for help.

Victoria Police's search and rescue unit, CFA, SES and Ambulance Victoria are at Werribee Gorge Circuit Track in Pentland Hills, in between Melbourne and Ballarat, after the call came in at 2.14pm on Sunday.

A SES spokesman said the women had become stuck while climbing and called emergency services to help them.

"They did have appropriate food, water and footwear. They just got themselves stuck and fatigued for a couple hours," he told AAP.

He said he understood the "terrain was too dangerous to do a high-angle rescue" so Victoria Police's search and rescue members decided to pull the women up the cliff face instead.

The women will then need to walk about three kilometres to be checked by Ambulance Victoria.

The age and climbing experience of the women is unknown.

The rescue is expected to be finished about 7pm.
