Thomas Keating, the boyfriend of a Victorian woman who was killed in a tragic jet-ski crash in Thailand, is expected to be formally interviewed and charged on Thursday.
Kyabram woman Emily Collie, 20, was killed when the holidaying couple's jet-skis crashed at high speed in waters off Phuket on Sunday.
Mr Keating, 22, told police that strong sunlight reflecting from the sea made it impossible for him to see the jet-ski being ridden by his girlfriend.
Thai police have said Mr Keating will be charged with reckless driving causing death.
