Noosa / Noosa Heads
The city of Noosa is really worth a trip, especially when you are on a backpacker tour down the Aussie East Coast. Wanna see rich people housing? Go and see Noosa. Its true, but Noosa does not only have a quite good number of "palaces", it also offers a beautiful landscape, many different sorts of activities and you can really enjoy your time in Noosa! Would do it again immediately!
Insider Tip:After a nice day of exploring Noosa with your hired bike, go to Noosa Beach House, a tiny noble Beach House Bar/Restaurant on the main street, it's really worth a visit! (Prices - average/affordable for backpackers)
