“Two divers have been found alive after spending nearly 22 hours missing in the ocean off the coast of North Stradbroke Island this morning.
The divers, 45-year-old Victoria Point man and 43-year-old Robina man, went missing around 10am on Saturday in waters off Point Lookout after they failed to return to the boat.
Just before 7am on Sunday, the men were spotted by an Australian Maritime Safety Authority Melbourne-based Challenger aircraft jet, who deployed a life raft to them.
It’s understood they were more than four kilometres offshore. “

Very lucky.

Yes, very. I don’t think they’d be able to see the shoreline, maybe some tall buildings out that far with just your head sticking out of the water.
