A UK tourist stranded on a boat off Indonesia has used her mobile phone to raise the alarm with her boyfriend in England.
He dialled 999 and was put through to coastguards in Falmouth, who alerted the Indonesian authorities to her plight.
Indonesian rescue workers, and coastguards in Australia, are trying to locate the tourist, who is believed to have run aground with some friends on a hired boat between Bali and Lombok.
The distance between the two islands is around 10 miles.
The woman, who has not been named, telephoned her boyfriend at 0230GMT on Wednesday, when the 23-foot boat she and her friends had hired ran aground.
She tried unsuccessfully to summon help locally and resorted to ringing her boyfriend back in England.
When Falmouth coastguards contacted her on her mobile phone, she was unable to give them her precise location.
By 1030GMT, the Indonesian authorities were informed of what had happened.
It is unclear how much danger the stricken tourists are in, but the duty watch officer at Falmouth said that making a long-distance mobile phone call was the right decision
He said: “Unless she can speak the local language, she wouldn’t get very far trying to ring the authorities in Indonesia herself.”
