This study reports on a series of 34 gully heads and other erosion features, such as scour holes (5 in total), located in channels in a catchment largely undisturbed by European activity in the Northern Territory, Australia over a 5 year period (2002–2007). The erosion features were monitored for their headward advance/retreat, enlargement or in-filling. The catchment was subject to a range of rainfall regimes and also was burnt every second year so that all grass cover was removed according to traditional management practice. The results show that the erosion features have changed little during this 5 year period. A remote sensing assessment found no relationship between erosion feature morphology and hillslope erosion. The monitored gullies heads and scour holes appear to be resilient landscape features. Significant linkages were found between hillslope erosion and change in erosion feature depth, indicative of a strong hillslope–channel coupling
