We booked an apartment in the Metzo Resort which was beautiful, located between Noosa Heads and Noosaville. There were cafes and restaurants within walking distance, although you had to drive to reach the main beach in Noosa Heads.
The next day, we had breakfast (or brekkie as the Aussies say) at a little café on the river, pretty much the only place in town to get breakfast for under $20 apiece. This also meant that we shared the café with a bunch of retirees, which we enjoyed! We spent the rest of the day in Noosa Heads checking out the shops, enjoying the beach and watching the sunset. There is also a national park that runs along the beach here. We were pretty tired so we passed on hiking through the park but it is supposed to be lovely.
