Foggy Reef is a boat-accessed wall dive at the southern end of the Lonsdale system inside Port Phillip Heads Marine National Park. A shallow lip drops into ledges and overhangs coated in soft corals, gorgonians, and sponges, with a busy temperate fish scene. Start on the lip, drop onto the wall, and make a disciplined turn before tide or swell starts to push the line off course.
