There's an article on Turley in The Age taken from the West Australian:
Health, career, family issues took former Eagle to edge

FORMER West Coast star Craig Turley has revealed that he contemplated suicide after aggravating an old back injury in 1997.
Turley, the 1991 Brownlow Medal runner-up and a player in the Eagles' most successful era, made the startling admission to the ABC television program Compass, which screened last night.
"Craig Turley: Heaven and Hell" plotted his upbringing under loving adoptive parents, his rise to stardom, a debilitating back injury received in 1992 and the discovery of his natural parents.
It also traced a plunge into depression when he hurt his back again while surfing after his AFL career had ended, and uncertainty about whether he had the strength to rehabilitate a second time.
"It got to a point where I felt that I didn't have the energy to work through it again," he said.
He has since carved a new life, working with young indigenous sportsmen in Perth.
In the documentary, Turley revealed he had believed he was part-Aborigine until he discovered his biological parents, though he said he still felt a strong affinity with indigenous people. He also told of the shock of learning that his biological father was a prominent West Australian Football League player.
Turley's biological parents have never been publicly named, but it is believed he is related to prominent AFL footballers of his era — one an Eagles teammate — on both his mother's and father's side.
