Hey Damned,
I've heard good things about Noosa River Holiday Park at Noosaville, a bit closer to Noosa beach than Tewantin is. Years ago, a mate was staying in a unit around there and we jumped into the river on our longboards on an outgoing tide and quickly found ourself at the surf beach besides Noosa Woods. (Got the wives to pick us up later and stopped at the pub on the way back. Happy days...)
And Point Lookout at Straddie looks sensational. I have only stayed in houses/units over there, but it's a wonderful spot for surfing and sightseeing (except during peak holiday time or schoolies, then it's awful

).
And thirty years ago I loved Flatrock Tent Park down between Lennox and Ballina but I think a couple of thousand homes may have been built around it since then. (Lennox at Lake Ainsworth is also good).
Did I mention Brunswick heads?



P.S. I think from past posts, Mac is your man re boards at Waikiki.
