The team has extensive experience in ecology, urban ecology, tree hollows, teaching and learning, and community engagement. The same team also runs the Cockatoo Wingtags program, which is researching a population of Sulphur-crested Cockatoos in Sydney. Twenty-nine councils are also involved in the project and are Auburn, Bankstown, Camden, Campbelltown, Canada Bay, Canterbury, Fairfield, Holroyd, Hunters Hills, Hurstville, Kogarah, Ku-ring-gai, Lane Cove, Leichhardt, Manly, Marrickville, Mosman, North Sydney, Parramatta, Penrith, Pittwater, Randwick, Rockdale, Strathfield, Sutherland, Sydney, Warringah, Waverley, Willoughby and Woollahra. In addition, the NSW Office of Environment and Heritage and Birdlife Australia are supportive of Hollows as Homes. By far the largest members of the team are the invaluable community participants that contribute all their valuable observations.
