yes i know where you are talking about

melros picks up most of the mandurah swell but during summer there are limited waves in mandurah

ive never seen anyone sail white hills im guessing you would be alone if you did and im sure if you get hurt or into trouble its a long slog back to the main road

im not sure of swell size in that area and not to sure of any direct access to spot XY but ive accessed XY from tims thicket heading south
