J.D. (John) Cregan was born in a coastal tourist town in southern New South Wales, where his parents owned a caravan park. He was raised to the sound of the wind and the sea, and spent his early years surfing and fishing.
Following a decade as a musician, playing support for bands like Men at Work and Mental as Anything, he moved to Western Australia, where he managed a drug rehab centre, a meditation centre, and a theatre company.
He released his first novel, 98%pure, in 2005. He lives in Fremantle, Western Australia.
