UPDATE: Thursday 6pm:
DOCTORS have said the 11-year-old boy who was bitten by a shark at Heron Island was "very lucky".
The black tip reef shark that bit his leg avoided most major arteries, surgeons at Lady Cilento said.
"The patient received surgery to his right calf muscle last night to clean the wound to ensure no infection develops," a hospital spokesperson said.
"Further surgeries to clean and close the wound will be undertaken in the next few days."
He will stay at the hospital for a week but is expected to make a full recovery.
The family of the Italian tourist has since thanked the support of hospital staff in Gladstone and Brisbane.
"It was a terrifying situation for our family but fortunately our son is going to be ok," his mother said.
She described their help as "fantastic".
"Thank you to all the doctors, nurses and everyone else who have been supporting me," the boy said.
The boy will remain in hospital for at least a week.
UPDATE Wednesday 12.30pm:
PARAMEDICS were cautious when moving the 11-year-old boy from the Ambulance to the Royal Flying Doctor plane this morning as he prepared to be flown to Brisbane.
The boy appeared to be calm and was accompanied by his mother.
His leg that was bitten by a shark yesterday on Heron Island was covered in a white sheet.

Reports suggest the boy was walking in knee-high water when he was bitten by a blacktip reef shark on his right leg - reported earlier by Queensland Ambulance Service as the left calf.

The boy's father took him to the medical centre where a registered nurse stationed on the island managed to stop the bleeding and gave the boy pain relief.
Paramedic Brad Lawson met the seaplane at Gladstone airport and said the boy, accompanied by his father and the nurse, seemed "quite happy" and was in minimal pain.
The boy is being examined by a medical team.
The duty manager at Heron Island Resort offered no comment instead directing enquiries to the managing company Delaware North's Melbourne Office, who did not answer the call.
