Hornsby Heights is a suburb of Northern Sydney, in the state of New South Wales, Australia. Hornsby Heights is located 26 kilometres north-west of the Sydney central business district, in the local government area of Hornsby Shire. The suburb is often referred to as part of the Upper North Shore. Hornsby Heights lies predominately on the high narrow ridges of the Hornsby Plateau above the eastern side of Galston Gorge and the Berowra Valley National Park which makes up the suburb's rugged and beautiful northern, western and much of its eastern boundaries. On the southern and southeastern side of the suburb, the boundaries meet with Hornsby and to a lesser extent, Asquith. The road entry to Hornsby Heights can only be made via Galston Rd through Hornsby from the south or from the north-west via Galston Gorge. The main characteristics of the area are its leafy bushland setting and the many short avenues leading to quiet cul de sacs branching off the 2 main roads, Galston and Sommerville Rds. The steepness of some of its streets are also a feature, as many have been cut into the surrounding valleys to maximise the available land close to the ridge edges. Bird and animal life abound in the suburb, with many species being regular visitors to resident's homes. Kangaroos, wallabies, common ringtail possums and echidnas abound in the mammalian world, while rainbow lorikeets, noisy miners and sulphur-crested cockatoos are some of the most common birds. The flora is rich and typical of the Australian native bushland in the Hornsby area. As with any bushland suburb, the area is subject to bushfire risk during summer so it has its own Rural Fire Service Brigade located on Galston Road.
