"Look, you're not going to believe this. I've got snakes on a plane."

On the ground, a firefighter discovered that the snake that crawled down Blennerhassett’s leg was not alone — a green tree frog was also on the aircraft, Nine News reported. No other wildlife was found and both animals had disappeared by the time a wildlife ranger came for them.

It is thought the snake, believed to be a non-venomous green tree snake, may have been hunting the frog, Nine News said.
