A WOMAN in her 60s has been airlifted to hospital in a serious condition after a boat overturned off North Stradbroke Island about 12.30pm on Sunday.
Redland Bay Coast Guard reported that a five metre tinnie had capsized and sunk on South Passage Bar, between North Stradbroke and Moreton Islands.
The boat contained the woman, a man in his 30s and two dogs.
Water police and Coast Guard vessels were deployed to assist with the rescue, as well as a Rescue 500 helicopter.
"Conditions were poor inside the bar with a strong ebbing tide," Redland Bay Coast Guard said on Facebook.
"Water police (arrived) on scene ahead of Coast Guard 71. A nearby vessel responded by retrieving the persons from the water.
"A rescue helicopter was on scene within minutes and winched paramedics to the Coast Guard Vessel to assist the persons on the assisting vessel."
The woman was airlifted to the Princess Alexandra Hospital in a serious condition.
The man was taken to One Mile by boat and was assessed by paramedics for minor superficial injuries. He declined transport to hospital.
A police spokesman said it was believed that one of the dogs had died.
Coast Guard recovered the sunken boat from within the bar.
"The vessel was righted and towed back inside the bar, from a great effort with the volunteers on board."
