Argyle Downs Airport (AGY)

Argyle Downs Airport (AGY) is a historic remote airfield situated in the East Kimberley region of Western Australia, primarily known for its role in serving the world-renowned Argyle Diamond Mine. Located approximately 120 kilometers south of Kununurra, the airport was a pioneer in the Australian aviation industry as one of the first dedicated hubs for Fly-In Fly-Out (FIFO) mining operations. For over 37 years, it facilitated the movement of thousands of workers who produced some of the world's most valuable pink and red diamonds, connecting this isolated outback location with Perth and Darwin. The terminal facilities at Argyle Downs were designed for industrial efficiency and the comfort of a large-scale mining workforce. During the mine's peak operation, the terminal featured a functional waiting lounge, administrative offices, and specialized security areas for the handling of high-value diamond shipments. The layout was minimalist yet highly effective, allowing for the rapid turnaround of regional jet and turboprop aircraft operated by carriers such as Airnorth and Alliance Aviation. Following the closure of the mine in late 2020, the terminal has transitioned to supporting the smaller teams responsible for the site's ongoing care, maintenance, and environmental rehabilitation. As of 2025, the Argyle Downs terminal is entering its final phase of existence, with Rio Tinto initiating a comprehensive decommissioning and demolition program for the site's remaining infrastructure. While the airstrip continues to be used for essential rehabilitation logistics and emergency medical services, the era of major personnel transfers has concluded. For aviation enthusiasts and historians, AGX remains a significant site representing the logistical ingenuity required to operate a global-scale resource project in one of the most remote and geographically challenging environments on earth.
