Browns Falls, Plunge waterfall in Killarney, Australia

Browns Falls is a waterfall in Killarney, Queensland, that drops about 15 meters over dark basalt columns formed by ancient volcanic activity. The water flows in multiple cascades between the distinctive rock formations, creating a series of streams as it descends.

The waterfall formed from the activity of the Main Range shield volcano, which shaped the Queensland landscape millions of years ago. The basalt columns are a direct result of this volcanic past that fundamentally formed the region's geological structure.

The falls sit on Spring Creek (South Branch) in the Darling Downs, just north of the Queensland–New South Wales border. They are one of five waterfalls around Killarney, alongside Teviot Falls at Teviot Gap to the north, Queen Mary Falls, Daggs Falls and Upper Browns Falls, so visitors often combine several in one outing.

Visitors must complete a creek walk of roughly 600 meters from Browns Picnic Area, which requires water-resistant footwear and careful foot placement. The route is demanding and the ground can be slippery, so allow enough time and proceed with caution.

Browns Falls is one of five waterfalls around Killarney; the others are Teviot Falls at Teviot Gap to the north, Queen Mary Falls, Daggs Falls and Upper Browns Falls. The falls sit just north of the Queensland–New South Wales border, about 4.5 km east of town.
