Three days ago rescue crews found the body of a woman who drowned in Moreton Bay on a fishing trip with her husband.
The couple's open fishing boat capsized near Mud Island in swells whipped up by strong winds.
Police reported that the boat capsized about 7pm on Saturday night within sight of the Port of Brisbane retaining walls.
The male clung to the boat but his wife was washed away. He was found Sunday morning.
Police acting senior Sergeant Mitch Gray said neither were wearing life jackets.
At the same time two jet ski riders became stranded, suffering hypothermia on mud flats on Russell Island after their machine broke down.
In other incidents a man drowned trying to paddle a kayak between North Stradbroke and Peel islands and in 2019 police rescued a second paddler after his kayak capsized off Wellington Point.
Police and Coast Guard continually warn about inexperienced people venturing into Moreton Bay in small craft not suitable for the big waterway's rough conditions.
In August last year two men died after their dinghy capsized off Green Island.
