The boyfriend of a Victorian woman who died in a jet-ski crash in Thailand will be charged by police.

Thai police said Thomas Keating, 22, would face a charge of reckless driving causing death after a jet-ski collided with another ridden by his girlfriend Emily Jayne Collie.

The pair were on holidays together on the Thai island of Phuket and were riding hired jet-skis at Kata Beach late on Sunday.

Mr Keating, who suffered minor injuries in the crash, told authorities he did not see the jet-ski ridden by his girlfriend because of strong sunlight reflecting off the water.

Lifeguards tried to revive Ms Collie, 20, from Kyabram, on the beach but she was later pronounced dead at a local hospital.

According to Phuket News, Thai police lieutenant Patiwat Yodkhwan told reporters on Monday: “Ms Collie’s boyfriend, Mr Keating, who was driving the other jet-ski when they collided, will face a charge of reckless driving causing death.”

“Her parents are coming to Phuket to collect her body and they are expected to arrive on Wednesday (Feb 8),” Lt Patiwat said.

“The boyfriend is in mourning and crying, so we cannot ask him much.

“The owner of the two jet-skis did not want money for the damage because he wants Phuket to have a good reputation as a holiday destination.

“In addition, the insurance coverage of the jet-ski will pay B50,000 compensation for the death of Ms Collie.

Mr Keating took Facebook to mourn the death of his girlfriend.

“I’m so broken and I know I’ll never never be able to mend,” he wrote.

“I’ll always be your boy and you’ll always be my girl! We had so many plans for our future Emmy.”

Friends also used Facebook to express their shock and pay tribute to Ms Collie, who was studying at Charles Sturt University.

“Such a beautiful and strong girl and I feel so blessed to have once been so close with you. Emily Jayne Collie you will forever be loved, hope there’s a nice big trampoline up there for you xxxx.”

“Cannot even accept that this has happened,” Ms Collie’s friend Steph Hanlon wrote.

Mr Keating’s sister, Bree Lyon, told Fairfax Media the family was “absolutely devastated” about the death of “our darling girl with those beautiful curls”.

“From the very moment I met you I loved you, I cherished your genuine heart, and that beautiful smile,” Ms Lyon said.

A spokesperson for the Department of Foreign Affairs and Trade said Ms Collie’s family were receiving consular assistance, but no other details would be released for privacy reasons.
