At dusk on the 20 March 2012 bird watcher David Koffel observed a large gliding possum glide between trees at the southern end of Lady Carrington Drive in Royal National Park. David reported his observation to the Royal National Park Visitors Centre and a spotlighting excursion was organised to investigate the sighting. On the 30 March 2012 David Koffel, Debbie Andrew and Glen Harvey located the glider and confirmed its identity as a greater glider Petauroides volans. This was the first confirmed observation of a greater glider in Royal National Park since the wildfire of 1994, 18 years prior, which burnt more than 90% of Royal National Park and 50% of neighbouring Garawarra State Conservation Area. An account of the sightings and background to the observations are provided.
