for bump and jump i reckon the best is mooloolaba but this time of year the wind is the wrong direction so most people either go to golden beach/caloundra bar or lake catharaba.
from caloundra to mooloolaba is about 25 minutes.
noosa to the Catharaba is about 30 minutes.
Mooloolaba - NW, N, NE
Lake Catharaba - SW, S, SE, E, N
flat water go to golden beach S, SE, E, NE, N
caloundra bar SW for bump and jump (incoming tide only)
you could also try cotton tree at maroochydore, i haven't sailed there myself.
