The drift from Inscription Point to The Monuments strings together the two best shore dives on the southern side of Botany Bay into one long one-way swim, and on the right tide it is the most relaxed way to see the Kurnell shore. It begins at The Steps platform below the Inscription Point car park, among large boulders close to shore, and once on the sand at about 10 m the incoming tide does most of the work, carrying you north-west along the reef edge past isolated rock outcrops in 12–14 m. The reef here carries some of the best sponge gardens in Sydney – sea fans, tube worms, ascidians and lace coral on every boulder – and it culminates in a prominent wall about three metres high honeycombed with overhangs and cave-like hollows, the same wall that Monuments divers reach from the other end.

The sand edge along the whole route is seadragon habitat: ten or more are regularly seen and up to twenty on a single drift, and this stretch was the study area for a seadragon tagging project in which one tagged animal was recovered 1.3 km away. White's seahorses live on the sponges, hawksbill turtles and grey nurse sharks have both been encountered, and stingrays, flathead, leatherjackets, bream, moray eels, cuttlefish, schooling catfish and a long list of nudibranchs fill in the rest. Navigation is about reading the wall and the sand gutters so that you can leave the reef and reach the Monuments inlet or the beach to its west; several exits exist across the sandy bottom.

It is only done on an incoming tide, it is superbly protected in a southerly, and it fails in north-easterly seas over about a metre. With a second car at the Monuments car park it is an easy hour of drifting past the richest reef in the bay, suitable for Open Water divers with a guide and a delight for photographers.

Two cars or a willing shuttle driver help. Park at the Inscription Point car park 1.5 km inside Kamay Botany Bay National Park at Kurnell, take the stairway from the middle of the car park halfway down the cliff and the walkway to the rock platform. Enter as for The Steps but instead of returning, drift north-west with the incoming tide along the reef for 40–60 minutes and exit at the small inlet by the whale sculpture at The Monuments, or on the beach west of it via the sand gutter, then walk 600 m back along the road to the car (or leave a second car at the Monuments car park).

Only on an incoming tide – the flood carries you north-west along the shore towards The Monuments; on the ebb you go nowhere or the wrong way. Excellent protection in southerly and south-easterly swell; problematic when north-to-east seas exceed 1–1.5 m, which make the Steps entry and the Monuments exit hard. Visibility along this stretch is usually never great, with five to seven metres considered especially good, though the Steps end can be clearer.

Invasive seagrass smothered the site in 1994–98 and again in the mid-2000s. Park gates lock at night.

From The Steps platform descend into the boulders, reach the sand at about 10 m and let the flood carry you north-west along the sand edge past isolated outcrops to the prominent three-metre wall with its overhangs and caves at 12–14 m. Watch for the wall changes and sand gutters that mark the exits; when you reach the Monuments wall, follow the seagrass gutter in to the inlet or beach and surface in the shallows.

Abyss Scuba Diving, Pro Dive Cronulla and Sydney Dive Academy run it as a guided drift when the tide suits; popular with experienced independents.
