A 33-year-old man died after being attacked by a shark on the Whitsundays Islands in northeastern Australia, and has become the third victim since September in the same area, local media reported on Monday.
The attack occurred on Monday afternoon at Cid Bay, where the man was swimming and paddleboarding with friends in a tourist area, according to local broadcaster ABC.
The man was evacuated to the hospital in Mackay, a city in the state of Queensland, to have an operation on wounds he sustained in his leg and wrist, but he did not survive it.
"He suffered several serious bites, a significant loss of blood and a heart attack," said Ben McCauley, one of the rescuers, who indicated that the injured had already received medical attention at the scene of the attack by paramedics, doctors who were on the site and a nurse.
Paramedics believe that this attack was worse than two previous ones, which occurred in separate incidents last September in Cid Bay, in which a 12-year-old girl lost her leg and another 46-year-old woman was seriously injured.
Before the September attacks, the Queensland authorities placed longlines and slaughtered six sharks, of which five were feared tiger sharks.
Shark attacks occur occasionally in Australia, where some 180 species of sharks inhabit.
According to studies by the government scientific agency CSIRO at the beginning of the year, Australia has about 2,210 adult specimens of white shark, considered the most dangerous.
