Thylungra sits roughly 100 kilometres northwest of Quilpie, in a stretch of country that swings between extremes. To the south spread open black-soil downs that flood and flush green; the north dissolves into mulga scrub and low red sandhills, the rest into stony range. Mitchell grass and Flinders grass carpet the floodplains after rain. Stands of gidgee and coolibah mark the watercourses, their timber dark against the bleached ground. In a region where evaporation devours far more moisture than the sky ever delivers, a reliable waterhole was not a convenience but the difference between survival and ruin. The Boonthamurra people who lived here understood that arithmetic intimately, and the place name they gave the land - permanent water - was the most valuable piece of knowledge anyone could carry across these plains.

Patrick Durack arrived in 1868 and established Thylungra alongside neighbouring Kyabra Station. He had already failed once: an earlier 1863 push into the southwest with his brother Michael and brother-in-law John Costello ended with their cattle dead in the drought. This time the gamble held. Within a decade the Duracks ran tens of thousands of head, pegging claims across roughly 17,000 square miles between Kyabra Creek and the Diamantina. Their saga became Australian legend when Patrick's granddaughter, Dame Mary Durack, told it in her 1959 book Kings in Grass Castles. The title is honest about the fragility of it all - fortunes built on grass and rain, in a place where both could vanish without warning.

The Durack story is usually told as triumph, and the courage it took was real. But this was Boonthamurra country, and the pastoral expansion that made the family wealthy took up land that was already home to people with their own deep history here - the very people whose word for permanent water the newcomers adopted for the station's name. Across the Channel Country, Boonthamurra and neighbouring Mithaka people would go on to work the cattle runs as stockmen and stockwomen for generations, their knowledge of the land woven into an industry that had displaced them from it. In 2015 the Boonthamurra people were finally recognised in native title over their traditional country. The grass castle, it turns out, was built on older ground.

In 1879 Patrick Durack left Thylungra for an even wilder frontier. He organised the overlanding of around 7,250 cattle and 200 horses some 3,000 miles to the Kimberley in Western Australia, to found Argyle Downs Station. It was the longest cattle drive Australian drovers had yet attempted. His cousins and a crew of hardened stockmen pushed the mob across two and a half years of country that killed roughly half the cattle and cost human lives as well. The drive entered folklore as a feat of endurance bordering on madness. Thylungra, the station where it all began, carried on without him - through droughts, shearers' strikes, the long Federation Drought that nearly emptied its paddocks, and a parade of owners across the next century and a half.

Thylungra survived everything the country threw at it. By the early 1900s it had shifted from cattle to sheep, with more than 100,000 head shorn in a single season. Ownership passed through banks, politicians, and pastoral companies; in 2008 it sold for 10.5 million dollars, spread across 2,820 square kilometres and stocked with 45,000 sheep and nearly 2,000 cattle. Then in March 2025 the old enemy reversed itself entirely: monsoonal floodwaters swept across the station, drowning the homestead and station buildings, with river levels at nearby Jundah surpassing the catastrophic floods of 1974. Permanent water, the name had promised. The land had a way of reminding everyone that it kept its own counsel.
