Large songbird, tawny with streaking above, paler below, with rich brown crown and long, graduated tail. In similar grassland and reedbed habitats, smaller Golden-headed Cisticola has much shorter tail, Little Grassbird is duller in plumage, and Australian Reed-Warbler has plain, unstreaked plumage. Calls often, with loud, grumpy churring calls and a longer call that starts “tick-tick-tick-tick” and ends with an explosive descending trill.
