'Extremely lucky': Elderly man found 48 hours after going missing

An 81-year-old has had a lucky rescue after he was missing for more than 48 hours in extreme weather in South Australia.

Christos Tryfopoulos was found on a remote beach near Dublin around lunchtime today.

Police said he was "extremely lucky" to be alive.

In the 48-plus hours since his family reported him missing, Mr Tryfopoulos would have endured weather including extremely cold temperatures, strong winds, and rain and hail.

Paramedics treated him at the scene for hypothermia before having him airlifted to the Royal Adelaide Hospital.

Police said Mr Tryfopoulos had been in good spirits when he was found.

He remains in a serious but stable condition in hospital.
