This wall runs east west just outside Port Phillip heads on the Point Nepean side. To go over the Nepean Wall you swim south from the shot. Descending to your desired depth you can swim in either direction along the wall but it is important that you return to the shot for your ascent as the current here turns very quickly. It is also a good idea to keep your bottom time shorter on this dive. This dive is only done on the ebb turning to flood so that at the end of your dive the current will bring you back into the bay. The wall along here is amazing with lots of soft coral and sponges. The fish life is amazing and this quite often brings fur seals into the area to feed. You can also bag the odd Cray or two.
