The sharks seemed in good health with no obvious cause of death, said local resident Lance Payne, who found them.
Mystery surrounds the reasons behind dozens of dead sharks that have been washed up onto a Queensland beach.
Construction site manager Lance Payne made the grim finds over two visits to the Louisa Creek Beach, on Australia’s east coast.
The 54-year-old said he said he found an “alarming number” of carcasses during his first visit in November, with at least eight more turning up on Sunday (3 December).
Payne, a keen conservationist, first came across the dead animals in mid-November. He was clearing the beach of coal, which he blames on production at a nearby local coal mine.
“They [the sharks] were strewn all over the beach… it was really alarming,” Payne told Yahoo7.
He added on Facebook: “The sharks seamed in quite good health with no evident cause of death [and] the corpses had not been predated on by other fish.”
But at the weekend the resident of the nearby city of Mackay returned to find more carcasses.
