An Australian couple who spent 26 hours in a crocodile swamp were rescued after scratching 'HELP' in huge letters in the mud.
Colen Nulgit and Shantelle Johnson and their puppy Ace were on a fishing trip in isolated terrain in the Northern Territory when their vehicle got stuck in the bog.
Fearing they'd be attacked by saltwater crocodiles, they wrote their big HELP sign, lit fires and waited to be rescued.
"We tried digging and we tried putting stuff under the tyres but it didn't budge," Ms Johnson told the ABC.
The couple got little sleep on Sunday night after earlier spotting crocodile tracks, with the tide bringing the reptiles close to the bank.
"We were stuck on the marshland and we were right next to saltwater," Nulgit told the ABC.
They stayed in the car the first night then saw the water rising.
"We grabbed everything and took it about 20, 30 metres from the car."
He said they were frightened but tried to think positive.
They had let family know where they were going.
Search teams eventually located the pair.
