An extensive search has been launched after a British man went missing while on holiday in Australia with his parents.

Benjamin Wyatt, from Bath, was last seen at Half Moon Bay, a beach in Melbourne, before disappearing about 2.15pm local time on Tuesday.

The 34-year-old, who is autistic, went missing while his family went to get the car, police said.

His parents have asked the public to help find their son, who was wearing a navy blue hoodie with a map of the Whitsundays on the back at the time.
