Funnily enough there isn't an actual town called just 'Noosa'. Noosa Heads is usually the spot people refer to when they say Noosa. There's also Noosaville, next door to Noosa Heads which is usually included in the broad Noosa area. To add confusion there are several precincts within these two towns that have their own names such as Noosa Junction (the shopping area within Noosa Heads), Noosa Waters, Noosa Sound, and Noosa Springs. Some outer lying areas such as Doonan and Tewantin are also thought of as being part of the broad Noosa area.
The word Noosa is derived from the aboriginal word 'Noothera' which means shade or shadows.
