Green (Laings) Point is an open grassland reserve with extensive harbour views. Then western tip of the point is still home to many relics, reminding visitors that this area played a significant role in the 1480m anti-submarine net that spanned the harbour entrance, built in 1942. The other end of the net attached to Georges Head. Midway through construction, in May 1942, was when the three Japanese midget submarines entered and attacked vessels in the harbour . From this headland, there are still some preserved parts of the net's construction, including the winch house foundations, the anti-motor torpedo boat defensive battery entrance and another battery. There is also a information sign with more details about the history of the area.
