Kakadu is Australia's largest national park, nearly 20,000 square kilometres, and Aboriginal people have lived here for around 65,000 years without a break. It is built around the Arnhem Land escarpment, a crimson sandstone wall carved over hundreds of millions of years and standing hundreds of metres above the plain. In the wet season that cliff line unleashes Jim Jim Falls, a single drop of up to 200 metres. By mid-year it is silent and dry. Below spread monsoon wetlands, still billabongs and the South Alligator River — saltwater crocodile country. The escarpment walls hold open-air galleries of rock painting at Ubirr and Nourlangie, some of the images up to 20,000 years old.
The Bininj and Mungguy people who own this land read six seasons rather than two, and the country turns with them. Floodwaters that seal off Jim Jim in January leave it bone-dry by August. Most travellers come in the dry season, June to October, when the roads open, the plunge pools are checked and opened for swimming, and animals crowd the shrinking waterholes. Climb Ubirr late in the day and the Nadab floodplain turns molten gold below you. Drift Yellow Water at dawn and crocodiles bask on the mud while the sky doubles on still water. The paintings at Nourlangie run from thousands of years back to the nineteenth century, and the late ones record what arrived: sailing ships, rifles, men in boots. Quiet as it can feel, this is not empty country. The park wraps around a block of Mirarr land it has never contained, where the Ranger uranium mine shut in 2021 and is now being rehabilitated for handback. The Bininj and Mungguy live here and have cared for the country without interruption.
