A committee was set up within the RFDS for advice to writers on aviation procedures/terminology, as well as medical and clinical processes and technical details. It was important to RFDS that the story br true to what they do, despite its fictional narrative.
Around 200 crew and cast were involved in the filming, over 5 months and the majority based themselves in Broken Hill during this time. The RFDS worked closely with the crew in the coordination of aircraft, staff, remote airstrip landings, filming at an operational base and set build -- despite challenges of 2020 with COVID lockdowns.
Both RFDS staff and the Broken Hill community were heavily involved with the number of extras required on set.
As one of Australia's oldest RFDS bases, the RFDS Broken Hill base was chosen as the location for filming due to its impressive red dirt landscapes, and the capacity to have filming set up alongside RFDS day-to-day operations without impacting delivery of primary health services and emergency medical retrievals. Broken Hill has long been a location favourite for filming for productions such as Mad Max 2, Priscilla Queen of the Desert, Mission Impossible II, Last Cab to Darwin and A Town Like Alice.
Once the Royal Flying Doctor Service had agreed to the project, producers Endemol Shine Banks started an extensive and very thorough research project so their writers and producers fully understood the work and service footprint of the Service. The RFDS took Endemol Shine to bases and clinics, facilitated the interviewing of doctors, nurses, pilots and patients. This process took more than a year - with scoping, scripting and pitches thoroughly worked and reworked until Channel 7 greenlit the series.
