Boolardy: Introduction

Mon, 22 Jun 2026 00:00:00 GMT

To hear the faintest whisper from the edge of the universe, you first have to find somewhere on Earth quiet enough to listen. Boolardy is that somewhere. For more than a century this was a working sheep and cattle run on the red Murchison plains of Western Australia, a leasehold of nearly 3,500 square kilometres roughly 800 kilometres north of Perth. Then in 2009 the CSIRO bought it for 5.42 million dollars, not for the wool or the cattle, but for the silence. There are no mobile towers here, no traffic, almost no people. The nearest neighbours are stars.

Boolardy now hosts the Murchison Radio-astronomy Observatory, since 2022 known by its Wajarri name, Inyarrimanha Ilgari Bundara, which means "sharing sky and stars." The site sits at the heart of a protected radio-quiet zone roughly 520 kilometres across, where governments restri...

Boolardy: Country Older Than Compass Needles

This is Wajarri Yamaji country, and the Wajarri have read this sky for far longer than any telescope has stood here. The 2022 land-use agreement that allowed the giant SKA-Low array to be built carries their name and their consent, and the observatory's title, "sharing sky and st...

Boolardy: Wool, Floods, and a Killing

The pastoral history is not gentle. Explorers Robert Austin and Kenneth Brown crossed the area in 1854, noting good grass and the vital Ngatta water hole, but settlers did not take up the lease until the 1870s, when it passed through the pioneering Wittenoom and Lefroy families. ...

Boolardy: Why Here, of All Places

Mon, 22 Jun 2026 00:00:00 GMT

The very things that made Boolardy a hard place to run cattle make it ideal for radio astronomy. Radio telescopes are exquisitely sensitive instruments, and the faint signals they chase, redshifted light from galaxies billions of years old, are easily drowned out by the electroma...

Boolardy: When the Plain Becomes a Sea

Drought is the default here. Little rain fell across 2012 and early 2013, raising dust storms and leaving stock with almost nothing green to eat. But the Murchison can flip without warning. In 1945 eight inches of rain fell in a single day and washed away more than a hundred mile...
