An adventure series following the experiences of a naval patrol boat, Patrol Boat rated reasonably well on Australian television and sold well overseas. Made in co-operation with the Royal Australian Navy (which, Moran points out in his Guide to Australian TV Series, 'had been trying to get something similar onto the screen for almost eight years'), the series made use of two naval patrol boats for open-sea shooting, including (for the second series) the Fremantle class patrol boat HMAS Defiance.
Moran notes that 'Guest stories included pursuing drug runners, helping a stranded refugee boat and destroying an old mine that had become dangerous to shipping. Each self-contained episode was constructed around two stories, one usually working around an individual sailor while the other concerned a larger group'.
Patrol Boat was the first program in which series creator James Davern's production company, JNP Film, had an active involvement, but Moran notes that JNP Film 'simply packaged scripts for the first series'. Their involvement was greater in the second series, which was made much later.
