Australian tourist fighting for life after being found with 'mystery' injuries in Bali

An Australian tourist is fighting for life in a Perth hospital, after being found with mystery injuries in Bali.

But how Sean Lance received these injuries and why he was unconscious is a mystery.

The 47-year-old father from Victoria is in a critical condition in the intensive care unit at Royal Perth Hospital.

His family says he was found unconscious in a ditch in Legian, Bali last Wednesday next to his scooter and helmet.

He was flown to Perth for treatment on Saturday with serious injuries. He woke up from a coma on Tuesday.

Mr Lance travels to Bali often, and the keys to the scooter were found in his pocket.

His family have taken to social media saying they believe he was bashed and there's no damage to the scooter.

This incident has the man's family desperate for answers to what exactly happened.
