I sailed there a few times years ago, and found it was pretty shallow in some places. I ended up cutting down a fin to 60cm to make it more forgiving. Not enough sailing time to know which areas are good or bad, sorry.

This was at the boat ramp (Palm Beach?), near the Greville (?) corner shop.

Out past the channel marker it is significantly deeper, but if I were sailing around there regularly I would be looking for a weed fin, just so that it doesn't hurt as much when you hit the shallow bits!

Since then I have bought a huge weedy but I haven't tried it.

I've seen formula boards and JP super lights get around no problem...well almost. There are a few shallow spots but once you get out and if the weeds not bad it'll be ok. If you stay east of the shallow marker your in the deep stuff, There's always JB which is a great spot for formula.

Thanks for the responses guys. Had a chat with a few guys at AGM last night and might look for another location on Jervis Bay rather than moving to Sanctuary Point.
