UPDATE 11am
POLICE say the 21-year-old who died after going missing while kayaking in Moreton Bay was an international university student.
Senior Sergeant Gary Worrell said the man, a Chinese national, had headed out kayaking from Dunwich to Peel Island on Wednesday morning with six friends, also international students.
The group called rescue services about 5pm, while heading back to Dunwich.
"Due to weather and the tide, (I'd suggest) they just became fatigued and they were not going to make land at that time," Senior Sergeant Worrell said.
Two kayaks were found about 6.30pm and another was found about 9pm.
Police and rescue organisations continued the search throughout the night for the remaining kayak.
"The search was hampered due to weather and light, a storm cell came over southern Moreton Bay which concluded Rescue 500 (helicopter) continuing on their aerial tasking," Senior Sergeant Worrell said.
"As a result of that we escalated our surface assets to increase throughout the evening.
"Earlier this morning, as crews were changing over, the weather abated and first light came (and) we decided we had the opportunity to again task Rescue 500, our emergency services helicopter, and Polair.
"The rescue services helicopter located the kayak, as a result Coast Guard Brisbane then unfortunately and sadly located a deceased male in the Rous Channel."
He said the kayakers had taken safety precautions, including wearing lifejackets and telling people where they were going.
"It was an unfortunate set of circumstances with the weather," he said.
"Our deepest sympathies are given to the family, the international student community and the university involved."
He said the other kayakers were assisting Dunwich police with investigations.
