The kunupalari frog often emerges at night, to avoid the heat of the day, and predators. It feeds mainly on ground dwelling insects such as centipedes, beetles and ants. Prey is captured by remaining motionless and pouncing quickly on any insects which wander past. A long, sticky tongue is used to draw the unlucky insect into the frog's mouth. Breeding occurs in milky pools in which tadpoles are hidden from view.
Breeding is in autumn and early winter or after summer rains.
Eggs are laid in a continuous string that settles to the bottom of a pool or creek. Females are generally bigger than males. Thousands of kunapalari frogs can be seen on warm summer nights after a shower. The rain brings them up out of their burrows, and large choruses of these frogs can often be heard calling in some areas of the wheatbelt. The call is a distinctive high pitched trilling call, which can be heard from some distance away.
