Ended up going up there. The place we stayed on Myall lakes was at the top end just near Seal Rocks.It was blowing a gusty S that came and went with rain.I was stuffed after 3 days sailing so had a snooze and by the time I went out I'd missed some good stuff.
Bit of a pain working up to clear the point so I was out of the bay but wow once I got a squall and out into the centre the runs were kms long , water clear and unpolluted , all bush and no sharks..

.. Blast! I could see the rain was going to end so turned around as sure enough the wind ran out and I was stranded standing on the point for a while until it came in a bit.
Wind came in later in the day c 18kts in gusts but I had sailed for 2hrs by then so didn't stay out long.Terrific place once your out in the open and I'd say great for jumps if the wind came in as it had some good ramps in 15 - 18kts.Someone suggested I launch around the corner at the boat ramp and next time I will as you're straight out into the wide open lake.
Went and had a look at the Wallis Lake sailing club spot and looks like it would be fantastic in the right wind. Really long runs..Would have been great in the S I had the day before.No wind then though so came home.
