It looks like his antics finally caught up with him.
Television personality and environmentalist Steve Irwin has died in a marine accident in north Queensland, state government sources say.
The 44-year-old is believed to have been killed by a stingray barb that went through his chest, the sources said.
He was filming an underwater documentary off Port Douglas when the accident occurred.
Mr Irwin’s body was being flown to Cairns by helicopter.
