Most of the 42 Australians who were in the area were last seen near the Gyirong border crossing and the nearby Friendship Bridge, a vital link that the flood completely destroyed; six of them have now been rescued, leaving 36 still missing.

The disaster obliterated kilometres of roads and dozens of bridges, rendering ground travel virtually impossible and forcing rescuers to rely on helicopters to deliver aid, evacuate the dead, and transport supplies, while drones are deployed to map the wrecked terrain from the air.

In response, Australia has dispatched a specialist team of 15 disaster experts equipped with drones to support search and rescue operations in the hard‑to‑reach Gyirong zone, working alongside Nepalese and Chinese authorities.

The concentration of missing Australians in this narrow border corridor means that any breakthrough there could bring closure to dozens of families and provide crucial information for both governments, highlighting how geography and destroyed infrastructure shape disaster response.

As long as the Gyirong border zone remains inaccessible by road, helicopters and drones will continue to be the only lifelines, underscoring why this specific area matters so much to the overall rescue mission.
