I should have said, when I was talking about the Food and Wine Festival, that it is only one part of the Noosa Fiesta, which runs for 90 days from May to July.
One of the other big events is the Noosa Longweekend Festival (June 17 to 26), which is a 10-day arts festival with lots of international performers - always a very diverse and creative line-up.
The Fiesta also includes the Noosa Winter Festival (May 21-22), which is a two-day sporting festival - cycling, swimming and running - run by the same people who do the Noosa Triathlon.
And there's the King of the Mountain Festival in Pomona (July 24), where not-very-sane people run to the top of Mt Cooroora and back and some ridiculously short time.
There are always lots of accommodation and restaurant deals during Fiesta as well, although I haven't seen any details yet. I will try to remember to come back to you on that one!
