The body of a UK holidaymaker who was killed while snorkelling in Malaysia was due to be flown home on Monday.
Joanna Stillwell was on holiday with her family
Joanna Stillwell, 23, from Leeds, was hit by a boat as she dived off the island of Redang early on Saturday.
She had been looking for turtles and baby sharks with her brother Nicholas, 18, but had swum 50ft beyond the official diving zone, police said.
Her father, John Stillwell said his daughter was the light of his family's lives and a "fantastic daughter".
"She was a fantastic girl, intelligent with an incredible zest for life."
Mr Stillwell, a geography professor at the University of Leeds, said police in Malaysia were still investigating the accident.
He said he was in his hotel with his wife Janet when he was informed.
"When I arrived, they had her in the boat and I spent some time in the boat with her. I believe she died in the water.
"I'm not sure if it was a speedboat or a boat used to transfer people to the island."
Mr Stillwell said his daughter had been travelling for the past 14 months and had taken time out to join the family on holiday in Malaysia.
He added: "We worried about her when she was travelling but she always kept in touch with family and friends via e-mail.
"It's ironic that she was with us when this awful thing happened."
She had been travelling through Thailand, Malaysia and Australia after graduating from Sheffield University with a degree in geography and politics in 2002.
