Old Man's Hat

Located in Sydney's North Harbour Aquatic Reserve, this dive site features a mix of boulders and rock ledges beginning at 14 meters and extending down to the sand at 25 meters. Around the 16-meter depth, there are interesting swim-throughs to explore. A notable aspect of this site is the abundant sponge life as you descend towards the sand, with numerous Sea Tulips, Lacy Corals, Sponges, and a diverse range of Nudibranchs. This Sydney dive site is excellent, offering plenty of opportunities to see Weedy Sea Dragons and other marine life.
