Gilly Paxton was walking along the Dunbogan beach on Saturday, June 27. She said the location was near the four-wheel-drive vehicle access and near the new development on Scarborough Way.

Gilly said she didn't expect to come across such a find on her daily walk.

"I was very hopeful it was dead but definitely kept my distance," she said.

"The markings on its tail looked really interesting."

The snake was identified as the yellow-bellied sea snake by a spokesperson from the Australian Museum.

"Some sea snakes including Hydrophis platurus have venom that could be potentially fatal to humans," the spokesperson said.

Even though the snake was beached, it can still pose a danger to humans.

"If you see a beached sea snake anywhere it's best to call a wildlife rescuer," the Australian Museum spokesperson said.

"Most sea snakes when on land have difficulty moving, and are unable to lift their body well.

"It's still recommendable not to touch them without training (obviously).

"In particular Hydrophis platurus are a pelagic species, so individuals that make it to land are generally very weak and in poor condition, and unlikely to survive."
