This arvo Hardy suggested, as it was very low tide, we remark the rocks at hardy's run.
Here's the results. (Just a guestimate, should have had a gps with us to mark the posts, but of course neither of us thought of that)
At the left of pic is the Navara boat ramp, the single rock marker is just out from the unpowered boat ramp.
The rock garden, (beware in here, at low tide the whole area is just a mine field of rocks, actually I think it's one big reef, with high spots), is opposite the big green roofed shelter in Len Howard conservation reserve. And the outside post should now include Claude's rock, (we had a good look around and all we found was big floating weed islands, I guess there could be more rocks under these, but it's impossible to tell)
To the right of the pic, there's a shallow area at the point where the shore goes into a bay at alpha land. There's a pole here marking the outer limit of this area.
So on a sufficiently high tide, there's a rock free run on the inside of the rock garden, if it isn't deep enough to go thru here, make sure you go outside the southerly post. If you can't point that high STOP!!!!!! before you cross the line between the south west and north west posts.
YOU HAVE BEEN WARNED!!!!!!!
