Essendon Fields Airport, colloquially known by its former name Essendon Airport, is a 305 ha public airport serving scheduled commercial, corporate-jet, charter and general aviation flights. It is located next to the intersection of the Tullamarine and Calder Freeways, in the north western suburb of Essendon Fields of Melbourne, Victoria, Australia. The airport is the closest to Melbourne's City Centre, approximately an 11 km (6.8 mi) drive north-west from it and 8 km (5.0 mi) south-east from Melbourne–Tullamarine Airport. In 1970, Tullamarine Airport replaced Essendon as Melbourne's main airport.
