Teenagers Found Drowned On Fraser Island Were On School Tour

Two 16-year-old boys whose bodies were found on Queensland's Fraser Island were part of a school group touring the area.

Queensland Police confirmed on Saturday the pair drowned overnight on the Island, north of Brisbane, after they were first reporting missing on Friday afternoon.

They were both Japanese nationals and just 16 years old.

Police believe the teenagers were not related but would have been known to each other as they were on the tour together.

Inspector Tony Clowes told reporters on Saturday that police were working very closely with the Japanese consulate and the families of both boys have now been informed of their deaths.

"This is a tragic event, there is no doubt about that," Clowes said.

"It certainly would be confronting to every person involved."

The pair were reported missing from their tour group near Lake Mackenzie at 5 pm on Friday afternoon.

A rescue search involving local officers, water police and helicopters followed and Police found the boys' bodies at 8.20 am on Saturday.

Clowes said it's believed the pair were not left behind by their tour group and added that a full investigation into a timeline of the tragic events would be taking place.

Police do not yet know whether the teenagers knew how to swim, but that would form part of their inquiries.

He said it was important for people to know their abilities and be aware there is always inherent risk in entering the water.

"We're in a nation surrounded by water, there's obviously a lot of concerns and safety issues that we have around that, we manage that as a country, there's nothing specific that I'm aware of in relation to Lake Mackenzie."

Police will prepare a report for the Coroner.
