Adults generally grow to 60 cm to 1 meter in length. The ridged scales and earthy tones of the Keelback provide excellent camouflage in grassy and aquatic habitats, where they spend much of their time.

Keelback Snakes are found across northern and eastern Australia, including parts of New South Wales and Queensland. They thrive in areas near freshwater sources such as streams, creeks, swamps, and dams. Keelbacks are semi-aquatic and excellent swimmers, frequently found hunting in or around water. They are also adaptable and sometimes venture into suburban gardens near wetland areas, where they continue to prey on frogs, fish, and small reptiles.
