Yeppoon Coast Guard deputy flotilla commander Paul Florian told ABC News the man was helped back into his boat by friends following the attack.
The 30-year-old was attacked off Miall Island near Rosslyn Bay, 420 miles (670km) north of Brisbane in Queensland.
Queensland Ambulance Service said the attack took place in waters off Rosslyn Bay, a resort popular with tourists visiting southern parts of the Great Barrier Reef.
The man suffered serious injuries to his hands and arms during the attack.
He said: “He was snorkelling a bit off the beach and said he saw a lot of fish and then the shark came out of nowhere”.
He was rescued by friends after coming to the surface who helped the man aboard the Coast Guard’s boat, which happened to be in the area. Shark sightings have also led to repeated beach closures, particularly along the coast of New South Wales, intensifying pressure on local authorities to take action.
Countryman underwent surgery following the shark attack, and was listed in stable condition overnight.
“Some of our veterans with the coast guard have been in this area for a long time and they can’t recall a shark attack – it is a very isolated incident”, he said. Despite the presence of a wide range of sharks along the Australian coastline, Queensland residents still expressed shock regarding Countryman’s attack, the first in the region in years.
