Hi all, This is my first post so please be gentle. I normally fish land based in Pittwater and last week noticed a lot of big Luderick cruising around the wharf I was on so I decided to pick up some green weed from a Northern Beaches Rocks location where I have previously found some. I went at low tide and the ocean swell was showing 3.1 metres on the tides4fishing website so i was aware that it could be a slight danger. When I got there and started my collecting the wash was just up to my ankles so it was ok but i was still wary as I had previously slipped over and broken my thumb last October doing the same thing with thongs on. I was just about to leave when this massive wave broke over the rock platform, which, when it got to me was above my waist. It picked me up and smashed me into the rocks, breaking my upper right arm near the shoulder. As you can guess I will be out of fishing action for some time so it has given me the time to write this account in the hope of keeping others safe. Reading further I found that with ocean swells you can get 3 waves a day which will be double the normal swell size. I found this out to my misfortune. Keep safe everyone and if anyone could PM me with a safe green weed collecting location on the northern beaches I would be most grateful as this incident has scared me immensely.
