A man who was bitten by a shark while working in his "dream job" as a wildlife ranger has died.
Zachary Robba, 23, was in the water off central Queensland, Australia, on his way back to a boat when he was attacked.
He was flown by helicopter to Gladstone Hospital with serious injuries and died just before 10pm on Monday.
On Facebook, the rector of his former school Iona College, Father Michael Twigg, wrote: "Zach, a Queensland Park and Wildlife ranger, was the victim of a shark attack yesterday afternoon, while working in water on the southern Barrier Reef.
"The group of rangers were undertaking research and essential maintenance on North West Island.
"This was Zach's dream job and he embraced all that it entailed.
"Zach's family are aware of our support through our communication with them and are appreciative of your love and care."
In a statement, Queensland's Minister for Environment and the Great Barrier Reef Leeanne Enoch said the news was devastating for Mr Robba's family, friends and colleagues.
"The ranger network is like a family, and we have lost a brother today," she said.
"I send my deepest condolences to his parents and loved ones."
Gabrielle Holmes spokeswoman for Capricorn Rescue Service said a helicopter was sent to the scene shortly after 6pm on Monday.
"The patient suffered significant injuries to their leg and arm and chest and were transported to Gladstone in a critical condition," she said.
"Our onboard critical care paramedic and doctor both performed significant medical treatment on the patient.
"It did take some time to get him stable enough for the flight but they were able to do so and get him to hospital."
