Two highly venomous sea snakes found washed up on the NSW south coast recently were returned to the ocean by a brave passerby.
The pair of yellow-bellied sea snakes were discovered at Congo Beach, south of Moruya, several hours apart and returned to the water by Carolyn Larcombe, the ABC reports.
The Burra resident said she recognised the species after finding another one washed ashore at Broulee.
"It was very quiet [and] I was able to put it over a stick and put it back in the water," she told the ABC.
It is believed turbulent weather conditions along the south coast caused the animals to become stranded.
The tropical ocean serpents breed in warm waters and are helpless on land.
While they usually live in the coastal waters of the Pacific and Indian oceans, the snakes have reportedly washed up on the shores of Hawaii, New Zealand and on the east coast of southern Africa.
A bite from a sea snake can cause damage to skeletal muscles, paralysis and renal damage.
