UK-born Hart has served 11 seasons as a lifeguard and spent time on the Aussie beaches. He says there weren't too many "naughty" beachgoers this year. "You occasionally got the odd jet ski coming in a bit too close and too fast but they moved on pretty quick. Other than that, there were a lot of happy members of the public enjoying their new contraptions they got over the Christmas holidays."
He says it's the small rescues that make his day. Helping reunite missing children with their families is always heart-warming and satisfying.
Both Hart and Miller say their serious injuries don't come during the job but in training and the sport of surf lifesaving. Miller once bit through his tongue when a wave hit his ski and knocked him out during training. His team-mates got him to hospital.
Hart is expecting a bit of a ribbing from his surf-club peers when the show hits the air, but nevertheless he is looking forward to viewing it.
So, does being a lifeguard help meet dates?
"People seem to have a thing about lifeguards – some wanting to stop for a chat, of course, some are nice-looking single ladies, but you have to get back to focusing on the job at hand," says Hart.
