ITV and Australian streamer Stan have co-commissioned a six-part detective series set in the Australian Outback. The Killings at Parrish Station follows Detective Georgia Cooke as she investigates a 1987 massacre and a similar case 37 years later. The show features Mia Wasikowska and Heather Mitchell portraying the lead at different stages of her life.
The Killings at Parrish Station is a new thriller series that blends cold case investigation with elements of conspiracy and mania. According to ITV, the story begins in 1987 when Detective Georgia Cooke, played by Mia Wasikowska, arrives at a remote research station in the Australian Outback. There, she probes the brutal murders of four scientists, with methods described as inexplicable, leaving a lone survivor as the primary suspect.
As Cooke delves into the case, it reveals layers of complexity that threaten her family, career, and mental well-being. The narrative spans two timelines, jumping forward 37 years to 2024, where an older Georgia, now portrayed by Heather Mitchell, faces a new series of murders mirroring the original incident. This forces her to revisit the unresolved horrors, raising questions about whether the past events were ever truly concluded.
The production unites talent from ITV Studios, HELIUM, and Stan. Julie Meldal-Johnsen, EVP of Global Content for ITV Studios, described the scripts as "smart, shocking, and suspenseful with raw human emotion," praising the acclaimed cast and crew. Michael Healy, Nine Entertainment’s Executive Director of Entertainment Content Commissioning, called it a "bold and distinctive series" led by creator Ben Jenkins, combining cosmic horror with cold case elements.
The cast includes Xavier Samuel, Robert Taylor, Alan Dale, Emma Lung, Doris Younane, Kat Hoyos, Nic English, Alex Malone, Geoff Morrell, Rob Carlton, Alex Lee, Cameron James, and Grace Owens. While no exact premiere date has been announced, the series is slated for release on ITV sometime in 2026.
