Police are now treating the deaths of two people found on a beach at Bribie Island, north of Brisbane, as an accident and no longer believe the circumstances are suspicious.
A passer-by who was inspecting turtle nests discovered the bodies about 8:00am on Saturday on the northern tip of Bribie Island.
An abandoned jet ski was found on the Pumicestone Passage side of the island.
Detectives said the man was a 39-year-old from Pelican Waters on the Sunshine Coast, and the woman was a 38-year-old tourist.
Their names were not being released to the public.
Police said they were awaiting autopsy results and would not comment further on the deaths.
Senior Sergeant Scott Wiggins said on Saturday the bodies were found on the ocean side of the island, and had been in the water for up to 24 hours.
At that stage, he said there were injuries on the bodies that concerned police, but that they were conducting forensic examinations to determine the nature of the injuries.
The northern end of Bribie Island is a thin, rugged strip of land that stretches north to a thin passage of water that separates it from Caloundra.
Four-wheel-drives are only permitted up to a certain point, north of which is a protected environment.
"By all accounts from some locals around this area, it's fairly common for people to park their tinnies or jet skis in the calm waters of the Pumicestone Passage and walk across Bribie Island to the open side and go for a swim in the surf there," Sergeant Wiggins said.
