Meet the site
The Jibbon reef complex is a cluster of deep reefs discovered by McFadyen and the St George Scuba Club from the 2000s onward, named in a running joke after fast-food outlets – because such outlets are always found near one another. Pizza Reef, named because it is round, came first; KFC, Maccas, Hungry Jacks, Red Rooster and Oporto followed as the club found neighbouring reefs, often by accident when wind pushed the boat off the intended mark. Pizza Reef, also listed by McFadyen as Fish Reef, is the original site and, in his view, one of the best reef dives in Sydney. It sits just south-east of Jibbon Bombora and is shaped like a figure 8, about 70 m long north–south and perhaps 30 m wide, rising from sand at 27 m to a top of about 22–23 m. Small overhangs run virtually all the way around, with some bigger ones, and a larger cave sits on the north-western corner. A large gully cuts north–south across the middle, dividing the reef into two halves, and a smaller reef about 50 by 30 m lies 10 m to the east. The fixed life is outstanding: gorgonians of many colours in the gaps between rocks, sponges and purple ascidians, on which donut nembrotha nudibranchs – once rare here – now appear regularly. Fish include bastard trumpeter, mosaic leatherjackets, bream, seapike, trevally and yellowtail, and cuttlefish, moray and serpent eels, numbrays and eastern blue devilfish live under the overhangs. Weedy sea dragons were once common but became scarce after 2018 (one was seen in May 2025). Seals visit occasionally, and humpback whale bones lie on the southern and western sides. The reef's pristine condition owes much to Royal National Park, which keeps runoff low and visibility good. Average depth over 25 m gives about 22 minutes on air. It suits experienced Advanced divers on nitrox.
