i reckon they were all day trippers up to the point.
Actually i think the campers on the beach this year were extremely well behaved, although we had great weather up until about the 27th, then the wind picked up and blew alot of people of the beach.
I've still managed to get a swim in everyday though..
If you find the right place (i tend to camp right down the bottom closest to noosa) end it's pretty good and quiet.. We have a great spot, spread out and simple.
There's still no place like it in OZ all the places i've been.
