Docker was born in 1964 in Narrogin, a remote wheatbelt town in Western Australia, the son of a motor mechanic and a medical secretary. His life journey would teach him that under the waving golden wheat is Wiilman Boodja, the traditional lands of the Nyoongar People, and that the Wiilman People are still here. At aged 2, he moved to even more remote Lort River Station, Coomalbidgup, in Wudjari Boodja, and grew up with his 3 brothers on a million acres owned by the Chase Manhattan Bank. After dropping out of engineering studies, and a failed attempt to join the banking industry, he studied writing at Curtin University (Whadjuk Boodja). He wrote his first play, concerning the issues of injustice surrounding the suicide of a close friend whilst in his teens. This desire to confront injustices would be a constant fire. Docker then studied acting at the VCA, Melbourne University (Lands of the Kulin Nations). He has worked extensively on stage, screen, and television, and writing many performance projects and radio plays along the way. In the early 90s, Docker's life took a swerve, and a series of events led him to become intimately involved with indigenous peoples, and their causes. These are human causes. SOMEONE ELSE'S COUNTRY is his first book (2005), where Docker shines a light on the madness, pain, and joy in his own life experiences. THE WATERBOYS (2011), a dystopian climate change thriller was shortlisted for Best Science Fiction Novel at the 2012 Aurealis awards in Sydney (Dhurug/Eora).His forthcoming work is set in and around the secret war being waged by Australian states against Aboriginal peoples.
