Meet the site
The 4th Hole is the local name for a tiny inlet cut into the cliffs of The Coast Golf Club at Little Bay, between the tee and the green of the fourth, and it is one of the more unusual and rewarding small shore dives in Sydney. From the inlet the bottom drops to a clear area at about 8 m enclosed by rising rock walls. Following the eastern wall you pass a swim-through between a rock and a ledge; to the south is a cave system with a small swim-through behind the main cave; to the south-west a fine vertical ledge holds a three-metre-deep cavity that is always packed with eastern rock blackfish and luderick; and northwards there are more niches and another swim-through, with 12 m reached beyond the southern ledge. Near the exit a long tunnel can be seen from inside but surge almost always makes it impassable. Port Jackson sharks and wobbegongs rest in the caves and, as at the neighbouring Little Bay, golf balls are the signature 'species'. The dive is small in area but dense in features and is noted as particularly good at night. Its difficulty is entirely about the entry and exit: the inlet is narrow, high tide pushes a seaward current through it, and any real swell makes it dangerous, so it is a dive for experienced shore divers on a flat day, with a hard 50 bar reserve for getting out. The golf club bistro at the top of the fairway is the traditional debrief venue. It pairs naturally with the Little Bay beach dive for a two-dive morning on the same golf course.
