Indian Point is the low headland between Congwong Bay and Henry Head on the northern shore of Botany Bay, and the reef off it is, in McFadyen's words, almost as good as Bare Island a few hundred metres to the west. From Congwong Beach the sand slopes gently out and the reef begins low and running slightly west, but after about 30 m it becomes a substantial near-vertical wall with its top at 9 m or less and sand at more than 15 m at its foot. The edge is perforated by more than thirteen small gutters and cracks running north–south, each a habitat in itself.

The sand below the wall is seadragon country, and the reef is one of the more reliable places in the bay for red Indianfish, which give the point its name as much as the local history does. Big-belly seahorses cling to the sponges, Port Jackson sharks lie in the gutters in winter, rays cruise the sand and turtles have been seen. The shallows carry large schools of surgeonfish, yellowtail and seapike, with bream, luderick and thousands of small mosaic leatherjackets; black reef leatherjackets, large blue gropers and cuttlefish work the overhangs.

A curiosity is the quantity of lost anchors and old bottles – some from the 1940s or earlier – that litter the reef, more than on any other Sydney dive. As a shore dive it demands a 10–12 minute swim each way from Congwong Beach and is for fit divers who are good on air; from a boat, anchored where the bottom rises from 15 to 9 m, it gives an easy, long dive on the wall. It sits inside Kamay Botany Bay National Park and is quiet compared with Bare Island next door.

Shore: park at the 'Snake Pit' car park opposite the bus terminus at La Perouse, take the stairs down to Congwong Beach (100 m) and swim on the surface then underwater east-south-east to the reef edge – 10–12 minutes of steady swimming, so only for fit divers who are good on air. Boat: from the Botany Bay ramps, 10–15 minutes from Kyeemagh; anchor where the bottom rises from 15 m to 9 m at the GPS mark. Boat diving is recommended for the longest time on the reef.

Inside the bay and protected from most ocean swell, but easterly and north-easterly swell rolls into Congwong Bay and creates surge on the 6–9 m reef top; southerly winds are fine. Tidal current runs along the reef edge and can make the return swim to the beach hard work – plan the shore dive around slack or a gentle flood and keep a healthy reserve. Visibility follows the bay pattern: best on the high or incoming tide, poor on the ebb after rain.

Boats anchor and fish along the edge – tow a flag from shore.

From Congwong Beach swim out over the sand to the reef edge, descend and turn right (south) with the wall on your left, exploring the gutters and cracks and the deeper sand at 15 m for seadragons. Continue for about 30 minutes or to half gas, then reverse and return along the reef top, surfacing near the beach.

Abyss Scuba Diving and Sydney Dive Academy occasionally run it as a boat or shore dive; mostly independent divers and St George Scuba Club.
