More than eleven hundred sand ridges run almost perfectly parallel across central Australia, north to south, some unbroken for two hundred kilometres - the longest parallel dunes anywhere on the planet. The Wangkangurru Yarluyandi people call this country Munga-Thirri, 'big sandhill country', and no name fits a landscape more exactly. Spread the dunes flat and you would carry a single grain of quartz across three states. But the Simpson is not empty space between somewhere and somewhere else. People lived here, raised families here, and read this seemingly blank ground like a map for at least five thousand years.

Simpson Desert: Big Sandhill Country

Photo credit User:Phanly (talk), CC BY 3.0. The dunes are the whole show, and they are stranger than they look. Each ridge is fixed in place, anchored by tough cane grass and spinifex, so the Simpson does not march or shift like a Saharan erg. It simply holds its pattern, sculpted long ago by winds that no longer blow that...

Beneath all that sand lies one of the largest groundwater systems on Earth, the Great Artesian Basin, and the Wangkangurru built their lives around the places it surfaced. They dug wells by hand, narrow shafts called mikiri sunk down to reach water hidden under the dunes, and the...

Simpson Desert: The Long Way Across

Photo credit V Ryabish, Public domain. Europeans arrived late and assumed the desert was uninhabitable - a misreading that says more about them than the land. The surveyors came first. In 1880, Augustus Poeppel marked the point where Queensland, South Australia and the Northern Territory meet, only to discover the lin...

Simpson Desert: Wheels, Boots and a Bass Drop

Photo credit Atlas of Living Australia, CC BY 2.0. Not until September 1962 did a vehicle make it across. Geologist Reg Sprigg drove from Andado to Birdsville with his wife Griselda and their two children riding along over roughly eleven hundred dunes - a family holiday that happened to be a first in history. After that came the ...

Simpson Desert: When the Desert Floods

Mon, 22 Jun 2026 00:00:00 GMT

Photo credit Atlas of Living Australia, CC BY 2.0. Call it a desert and the word does it a disservice. Rain averages around a hundred and fifty millimetres a year and summer heat climbs toward fifty degrees, yet the Simpson sits inside the Lake Eyre Basin, a vast inland drainage where water, when it finally comes, transforms ever...
