The families of a couple missing in a national park on Western Australia's south coast say they are praying for a positive outcome.
A searched resumed this morning for Geoffrey Bignell, 20, and Victoria McCloy, 22, in the Torndirrup National Park, south of Albany.
The pair last contacted family via a mobile phone on Friday.
Their vehicle, a black Holden Barina, was found in a carpark at the Bald Head Trail on Monday morning.
A large-scale search started yesterday with emergency services, sea rescue and aircraft scouring the rugged coastline.
The searched resumed at first light today, with clear conditions aiding efforts.
Hoping for breakthrough
Victoria's aunt, Chrystal McCloy, said the Northam couple's families were headed to Albany to help with the search.
"We would like to thank everybody in the community who has helped in regard to the search," Ms McCloy said in a message to the ABC.
"A massive thank you to police, air and sea crews, SES and anyone else that has been involved.
"We are praying for a positive outcome."
Dangerous tourist hotspot
The Bald Head Trail is a popular destination for tourists, with the 13-kilometre hike offering stunning vistas of the surrounding Torndirrup National Park.
The park is known for dangerous coastal conditions, with several drowning deaths in recent years at Salmon Holes and The Gap.
Signs warning of dangerous coastal conditions including king waves and cliff edges are posted along roads into the area.
Great Southern District Superintendent Ian Clarke said it is believed the couple intended to go rock fishing in the area.
"They have come here with the intent to go rock fishing, that's one of the areas we are concentrating on with our search," he said.
"They have previously lived in Albany and have some familiarity in the area.
"Mr Bignell has been fishing here before and has some understanding of the area and its hazards.
"We are hoping for the best."
The road to Salmon Holes and the Bald Head Trail is closed while police search for the missing couple.
Supt. Clarke said anyone who saw the couple's vehicle or the couple between Friday should contact police on 1800 333 000.
