Police have confirmed the identity of one of the two bodies found washed up on the beach at Bribie Island, north of Brisbane yesterday.
Detectives said the man was a 39-year-old from Pelican Waters on the Sunshine Coast.
His name is not being released to the public.
Police are yet to formally identify the woman, who is believed to be 38 years old and a foreign national.
Police say they will await autopsy results before ruling out their initial concerns that the deaths were suspicious.
A passer-by who was inspecting turtle nests discovered the bodies at about 8:00am on Saturday on the northern tip of Bribie Island.
An abandoned jet ski was found nearby.
Senior Sergeant Scott Wiggins from Sunshine Coast police said on Saturday the bodies were found on the ocean side and had been in the water for up to 24 hours.
