A British man went missing while snorkelling during a dream holiday in Bali and his family are desperately trying to find him.
Graham Smith, 67, vanished off the idyllic Blue Lagoon bay in the Padangbai area of the Indonesian island.
The dad-of-six and granddad-of-11, from Gravesend in Kent, was celebrating retirement with his partner of 36 years Dianne when the tragedy happened.
The man ran into difficulties while exploring Bali's waters on September 28, his partner Dianne said.
The woman raised the alarm at 5.20pm, after she lost sight of him and he failed to return.
She alerted locals and a search mission was launched, but Mr Smith could not be found.
The official Balinese search for him has now come to an end and the family is desperately trying to extend the mission.
Three of Mr Smith's sons and daughters-in-law made the 36-hour journey to assist and support Dianne.
They want to raise money for a private search mission and have set up a JustGiving page to help them reach their goal. So far, they have raised over £20,600.
The family will use the money to conduct an extra two-day search and said that hiring a helicopter costs £1,600 per hour.
Mr Smith's son Adam posted on the fundraising page, describing his dad as a selfless family man with a "heart of gold" who puts "humour and care at the forefront of every day".
He said his dad is an active and adventurous man, who loves to travel and explore.
While he is not a very strong swimmer, he said the retiree knows his limits and doesn't take unnecessary risks.
Mr Smith is known to his grandchildren as "Grandad Gray" and on return to Britain, he had been planning to teach three of his grandchildren woodwork skills.
The family desperately wants to bring him home and a post on the fundraising page adds: "This stage of his life is only just beginning, with, promises still to uphold and a life to live.
"He is a resourceful man who has been an electrical engineer, a lumberjack and handyman who devotes his life to helping his family.
"This is our moment to try and help him come home."
The family also passed on their thanks to the Bali search and rescue teams who they said have worked tirelessly to try and find Graham.
They said: "We would also like to thank the Royal Karma Hotel Group, where Graham and now his family are staying who have gone above and beyond to support us.
"Naturally we are all extremely distressed and we need all the help and support we can get. Please help us find him.
"We absolutely cannot go home without him."
