British man dies at Aussie tourist hotspot

Two men, including a UK national, have died in a horror car crash on South Australia's Kangaroo Island.

The British man, aged 26, and a 55-year-old man from Woodcroft died in a single vehicle rollover at Cuttlefish Bay.

Emergency services were called to the scene on Cape Willoughby Road about 11.30pm, South Australian Police said on Thursday morning.

The driver, a 42-year-old man from Hackham West, has been arrested and charged with two counts of causing death by the careless use of a motor vehicle.

"Major Crash Investigators travelled to the scene early this morning and examined the circumstances surrounding the crash," the police said.

"The driver has since been arrested and charged with two counts of cause death by careless use of a motor vehicle.

"He has been bailed to appear in the Kingscote Magistrates Court on November 17."

The deaths of the two men mark the 58th and 59th lives lost on South Australian roads this year.
