They installed five prototypes. Within a week, a female koala named "Bumpy" (for the scar on her nose) was photographed climbing one, pausing at a ledge, and using it to cross over the tracks without ever touching the ground. The panel had a small, circular opening near the top—a "window" through which a koala could observe the other side before committing. Reyes, an amateur photographer, captured Bumpy peering through that hole, her furry face framed like a portrait. The image went viral locally. "Koala Window" stuck.
This is the story of how a problem became a solution, and how a solution changed the way a country thought about its roads. koala windows
A young wildlife ecologist named Dr. Maya Lin was tasked with monitoring the corridor. She placed heat-motion cameras on five signal posts. Over three months, she recorded 147 koala approaches. 119 ended with the koala climbing the post. 12 of those koalas were later struck by trains after descending onto the tracks. They installed five prototypes
Today, Koala Windows are standard infrastructure on new road and rail projects in Queensland and New South Wales. They have been adapted for squirrel gliders (smaller ledges), spotted-tailed quolls (wider platforms), and even tree frogs (grooves that hold water). The design was open-sourced by the Australian government in 2021. Versions now exist in Japan (for raccoon dogs), Brazil (for golden lion tamarins), and Canada (for martens).
