A couple have been rescued after four days bogged on a remote Nullarbor track while on a bushbashing expedition.

Carl and Rose Jakeway began stockpiling their urine as the days ticked by and they were unable to dig out their Ford Ranger, which had sunk into thick red clay.

The South Australian couple had chosen to take a back track on their way to visit family in Western Australia, heading south from the Cocklebiddy Roadhouse, the ABC reports.

But the experienced bush drivers became trapped when they reached a damp section of track and their vehicle sunk deep into the mud.

“We spent days digging and digging, just trying to get this red clay out of there,” Jakeway told the ABC.

Although they were carrying a personal locator beacon, the ABC reports the Jakeways opted not to use it as they attempted to free the vehicle themselves.

They were carrying food and water, but as their water supplies began to dwindle they started planning for survival.

“We started saving urine, thinking that in two or three or four days that we may need to use that,” Jakeway said.

“Fortunately, we didn’t have to.”

On about day three trapped on the Nullarbor, their jack broke, leaving very little chance that the couple would be able to extricate the 4WD.

“There was no way I could jack up the vehicle anymore to try and get sticks and rocks under any wheels, to give us some clearance,” Jakeway told the ABC.

“Once the jack broke, that was it.”

They activated their personal locator beacon last Friday, sparking a large-scale operation to track down and rescue them.

WA Police said the operation involved Eucla and Norseman Police, Police Air Wing and the Emergency Operations Unit. At first, rescue officers could not get into the area due to recent heavy rain so the search was suspended for a day.

It resumed on Saturday, when the Police Air Wing was brought in.

“Police Air Wing officers contacted the male driver of the Ford, and after communicating the location of the vehicle to Eucla Police, officers attended and assisted in extracting the Ford from the mud,” said WA Police.

“The man and woman were uninjured and in good health.”

Police thanked the community – especially staff at the Cocklebiddy Roadhouse – for their assistance during the search.
