Charlie Fry, 25, was left with superficial puncture wounds on his right shoulder and upper arm after the attack on Monday afternoon off Avoca Beach, 90 kilometres (60 miles) north of Sydney.
"I saw a shark's head come out of the water with it's teeth and I just punched it in the face", he told Nine News.
"I just punched it with my left hand and shouted out to my mates and paddled so hard back to shore", he told the Daily Telegraph. "So Mick, if you're watching or listening, I owe you a beer".
A United Kingdom tourist has fought off a shark by "punching it in the face", after he was attacked on the NSW Central Coast yesterday afternoon.
Mr Fry, a doctor from the United Kingdom, is in good spirits and is expected to make a full recovery.
"So when it happened, I was, like: Just do what Mick did".
'I instantly just jumped away.
Police said in a statement the man's injuries were not serious. "I've just gotten here and I've already been attacked". It was very, very hectic.
And Charlie revealed how he miraculously managed to escape with only one minor bite mark.
He was driven to a nearby hospital by his companions instead.
The 25-year-old was taken from the beach to the Gosford Hospital where he works.
Mr Fry said he had "no idea" what kind of shark it was, but said it was "big and scary".
"It was terrifying but it only lasted five seconds". The Sun reported that lifeguards spotted a great white shark, reported to be an estimated 10-feet long, and a bronze whaler shark in the area shortly afterwards.
Avoca beach will remain closed for most of Tuesday as a result of the attack.
