This grasswren lives on rocky hills near Mount Isa, moving on the ground through spinifex clumps. Its range and biology remain incompletely studied.
It is brown overall. Females have a distinct rufous patch on the flanks that males lack. The related Carpentarian Grasswren has a white throat and breast, which helps distinguish it in the field.
It runs or hops on the ground and perches on rocks or low branches. It rarely flies, and when escaping may fly downhill. It eats insects and seeds; fruit is possible, but detailed diet studies have not been done.
An extinction-risk assessment has not been added yet.
