Nabarlek

Petrogale concinna

Also known as Pygmy Rock-wallaby, Little Rock-wallaby

Nabarleks are diminutive rock-wallabies adapted to navigating the sheer sandstone cliffs and boulder fields of northern Australia. They spend daylight hours concealed deep within labyrinthine rock fissures to avoid the oppressive heat, emerging after dusk to forage on tough native grasses and ferns. Uniquely among macropods, they possess an endless conveyor belt of molars that continuously migrate forward and fall out, allowing them to grind abrasive, silica-rich vegetation without starving.

What to notice
Look for a tiny grey rock-wallaby with a rufous wash over the shoulders, a faint cheek stripe, and a bushy tail.
Support conservation
Maintain a generous viewing distance, avoid shining bright white lights into sheltering rock crevices, and keep pets leashed.
Responsible observation
  • Viewing Time: Scan rocky escarpment margins quietly at twilight with a red-filtered spotlight.
  • Noise Discipline: Maintain quiet observation, as this timid wallaby flees deep into boulders when startled.
