When three friends set off for a drive through the Australian outback last month, the few provisions they packed – beef noodles, biscuits and some cans of vodka – indicated they didn’t expect to be gone long.

Then things went terribly awry.

On November 19, as the trio passed over a riverbed, their car got stuck.

For three days, Tamra McBeath-Riley, 52, Claire Hockridge, 46, and Phu Tran, 40, tried to dig it out, surviving off what little they had with them in hopes they would soon be back on the road, the BBC reported. As their circumstances grew more dire and the car wouldn’t budge, they moved toward a nearby watering hole with McBeath-Riley’s dog, Raya.

Fearing the worst as days passed and no one came to their rescue, they separated sometime around Thursday, hoping one of them would find help and guide rescuers to the others. Hockridge and Tran set out on foot together with a GPS and a compass. McBeath-Riley stayed back with Raya, close to the water she knew they needed to survive.
