The number of species is increasing at Ivory's Rock as urban development displaces wildlife. The Eastern Grey Kangaroos arrived in 2013, settling in well with the resident wallabies.
More birds are also being recorded, including migratory birds. Pelicans have been seen in the last few years on the lake.
A diversity of flowering and old growth trees provide for the birds and bats, with the wattles, bushes and grasses supporting the ground dwelling animals and reptiles.
