East North Bommie is one of a group of bommies north-east of Ulladulla Harbour that the local shop simply calls the North Bommies. Michael McFadyen describes this one as a reef running north–south, with its top at 20 m and a sand edge at about 25–26 m. Small boulders line the sand edge, and further along are bigger boulders and sections of wall with small overhangs and cracks. It is only just under two kilometres from the wharf, so the boat ride is short and the site is often dived when conditions rule out the longer run south.

The depth brings good invertebrate life. Sponges are the standout, with colourful encrusting and upright forms, plus sea squirts, gorgonians and lace corals growing on the walls. The fish are what the North Bommies are known for: the Marine Life Network describes walls, canyons and boulders teeming with yellowtail and pomfrets, and McFadyen adds weedy sea dragons over the kelp and sand edge, moray eels in cracks, eastern blue devilfish under overhangs and nannygai around the deeper boulders. The shallower main North Bommie nearby (about 18 m) has a small cave the operator calls The Penthouse, and a North-East Bommie at 10–14 m gives a gentler alternative.

The site suits Advanced Open Water divers, or Open Water divers with a guide, because the whole dive is spent between 20 and 26 m. It is a straightforward out-and-back along the sand edge and reef face, which makes navigation easy. It is a good place to look for sea dragons and devilfish, and to photograph the sponge-covered walls. It lacks the drama of Burrill Rocks, but it is closer, reliable and usually has plenty of fish.

Boat access only. Charters and private boats launch from the public ramp inside Ulladulla Harbour, reached off the Princes Highway in the centre of Ulladulla (about three hours' drive south of Sydney); there is trailer parking around the harbour and the dive shop is a short walk away. Leave the harbour and head north-east; the bommie is just under 2 km from the wharf, a five-minute run.

Anchor on the top of the reef at about 20 m. The site is close enough that it is often the second dive of a double, or the choice when a southerly swell makes Burrill Rocks unpleasant.

Because it is so close to the harbour this is a reliable fall-back site. It is exposed to easterly and north-easterly seas, but the depth of the reef top (20 m) keeps divers below most surge. A southerly swell of up to about 1.5–2 m is usually manageable as the run is short and partly sheltered by Warden Head.

Strong north-easterly afternoon winds in summer make anchoring and recovery uncomfortable, so dive in the morning. Visibility falls after heavy rain and big seas.

Descend to the reef top at 20 m, drop east to the sand at 25–26 m and follow the sand edge north for about 12 minutes, checking the small boulders and overhangs. Turn and come back south along the main reef section, working up the face to 20 m, and ascend the anchor line with a safety stop.

Dive Adventures Ulladulla runs the North Bommie complex regularly (lists North Bommie at max 22 m with a shallow cave called The Penthouse); East North Bommie is dived on the same trips for advanced divers. Private boats from Ulladulla Harbour.
