by the sound of it you shouldn't go, the west coast eats east coasters up.

There's a strong SSW forecast and a large swell, I'm guessing ur not familiar with the area I suggest you go further north say around Perth area, or if you are already in margs go to the boat ramp (gnarabar)

Augusta no good on a SSW unless u want to kite J's beach, oh and the cut is pretty much closed so no drama crossing it.
