Matt Le Feuvre had never been anywhere quite so remote nor beautiful ‒ a pristine gorge nestled in the far northwestern Kimberley.

"It was just a stunning spot," he says. "We had our own little glade of rainforest coming down to the riverside. The sandstone was beautifully polished by the wet season flows, so you could basically walk around barefoot everywhere. We had quolls coming into our camp at sunset every night, and monjons, which are tiny hopping kangaroos."

Le Feuvre and his collaborator James Shelley, both PhD candidates at the University of Melbourne, were there to catch fish. The Kimberley region in Western Australia is known for its dazzling array of endemic freshwater species, but very little is known about them; scientific expeditions have been few and far between.
