The man killed by a shark at Byron Bay in New South Wales joked with his parents during their last conversation about the risk sharks posed.
Paul Wilcox, 50, bled to death after a large shark, possibly a great white, took off part of his right leg as he swam off Clarkes Beach on Tuesday.
His grieving parents, Bryan and Marie Wilcox, who live in Wales, have revealed they spoke to their son about sharks soon before he set off on the final swim of his life.
"This subject came up in a joke when we last spoke to him," Mr Wilcox told the Rhyl, Prestatyn and Abergele Journal in Wales.
"But he said there had only been three shark attacks in the last 12 years. It's just extraordinary."
