A widespread species that is largely found in eastern Australia. It is naturalised in inland southern and central Queensland, throughout much of New South Wales, in the ACT, in northern Victoria, in the southern parts of South Australia and in the coastal districts of south-western Western Australia.
This short-lived grass is mainly recognised as a agricultural weed, but it was recently also listed as a priority environmental weed in two Natural Resource Management regions. Spiny burrgrass (Cenchrus incertus) usually grows on sandy soils in disturbed areas (e.g. on roadsides, in pastures, in gardens, and in crops and cultivation), but also invades native rangelands, grasslands, open woodlands and coastal environs.
