Ray Boseley began his screenwriting career with the short comedic film Smoke 'Em if You Got 'Em. Though he has continued to write the occasional film script (including the short film 'Prickly Heat', aired as part of Five Easy Pizzas at the 1994 Melbourne International Film Festival, and the forthcoming Nim's Island 2), he soon moved into working primarily on television scripts.
Some of Boseley's earliest television scripts were for the Australian Children's Television Foundation (ACTF), where Patricia Edgar described him as having 'an inventive, unconventional mind' (Bloodbath: A Memoir of Australian Television, Melbourne: Melbourne UP, 2006, p.317). His work for the ACTF includes scripts for Sky Trackers, Lift Off, and Legacy of the Silver Shadow.
As well as his work on speculative-fiction children's television, he has also written for crime programs (Good Guys, Bad Guys) and comedy (Kenny's World).
