In a move he learned from Australian surfer Mick Fanning, who famously punched a shark at a 2015 World Surf League (WSL) event in South Africa, Fry punched the fish in the face with his left hand.
"If you are watching or listening, Mick, I owe you a beer, thank you very much".
After only being in Australia for two months, the recovering doctor said he's not sure if he'll share the news back home.
"I saw its jaw and teeth coming at me", Mr Fry told the Daily Telegraph.
Dr Fry said he managed to "scramble back on my board, shout at my friends and luckily a wave came, so I just sort of surfed the wave in".
"I was just surfing, (saying) get in as fast as possible, ride the wave as fast as possible, ride the wave as long as you can and start paddling for your life essentially".
"Geez I don't know if I can tell mum, she might kill me", he said.
"I turned and I saw this shark come out of the water and breach its head", he said.
But lifeguards spotted a great white and a bronze whaler in the area shortly after the incident.
Fray said he wasn't conscious of his injured and bleeding arm until he reached the shore.
"I didn't feel the teeth going in, it felt like I was smacked, it felt like a hand, a hand grabbing me, shaking me", Fry said.
Two of his friends who were with him at time are also doctors so they tended to his injuries before taking him to Gosford Hospital where he also happens to work.
A 25-year-old man is recovering in an Australian hospital after fighting off a shark on NSW's Central Coast.
"North Avoca and Avoca beaches are now closed following a shark attack", the council said.
But he was more anxious about what his mum would say than about the injuries themselves.
