Does anyone know if you can foil in Noosa River, Noosaville off caravan park grounds?

Possible, yes, but the runs are pretty short and it's a shallow river.
If you can get to the river mouth on high tide I think it will be better.
Also, the river is very dark at the moment so sand banks are difficult to see.
See you there one day.....

Won't be there until June. My foil is slowish so hope to not do too much damage if worst comes to worst. Thanks Dantren.
Not much wave sailing that time of the year with lightish winds from SE?

It's mostly a windsup place for me, unless I get out in Laguna Bay.

Drive to Boreen Point, Lake Cootharaba, about 20km north. One of the best sailing venues, foil or fin, you will find in the S.E. Queensland area.
