Bundegi is the easiest reef to reach from Exmouth town and the only one on the gulf side of the Cape with a sanctuary zone right off a beach car park. The reef fringes the eastern shore of North West Cape just south of the Navy Pier, and it has attracted scientific interest for having one of the highest coral recruitment rates recorded — a sign of how productive the nutrient-rich waters of Exmouth Gulf are.

The structure is a band of coral bommies and large boulder (massive Porites) corals on a sand and seagrass floor in 3–10 m. Plate and staghorn corals fill the gaps, and the seagrass beds between shore and reef are grazed by turtles and occasionally dugong. Fish life is typical of an inshore tropical reef: Spanish flag snapper, coral trout, sweetlips, rabbitfish, parrotfish and schools of fusiliers, with reef sharks and stingrays on the sand. Manta rays pass through the gulf at times, and whale sharks and humpback whales are sometimes seen offshore in season.

The catch is the distance. The good reef is a few hundred metres out and a busy boating channel must be crossed, which is why snorkelling guides rate it as an advanced shore swim. The Bundegi Sanctuary Zone Kayak Trail, with moorings designed for kayaks, is the practical way to reach it with scuba or snorkel gear. Visibility is usually lower than on the ocean side, and the site is far better on a calm morning.

It is a useful option for independent divers staying in Exmouth who want a shore dive without the drive to Cape Range, for training, and for a quick look at gulf reef between boat days. Hard coral here was affected by the 2025 marine heatwave to some degree, so expect patches of dead or recovering coral.

Drive 14 km north of Exmouth on Murat Road (sealed, 2WD) and turn off to Bundegi Beach, where there is a large car park beside the boat ramp. Gear is carried only a short distance to the sand. The better reef lies 200–500 m offshore and a boating channel (about 8 m deep) must be crossed, so fly a dive flag and keep clear of the ramp traffic.

Many visitors instead use the Bundegi Sanctuary Zone Kayak Trail, paddling to the designated kayak moorings and snorkelling or diving from there. Operators also use Bundegi ramp as their launch point for Lighthouse Bay and Muiron trips, and some run short gulf dives here.

Sheltered from the Indian Ocean swell, but exposed to easterly and north-easterly winds across the gulf, which chop up the surface and reduce visibility. Best on calm mornings before the afternoon sea breeze. Tidal streams run along this part of the gulf; plan around slack water or a gentle flood and avoid big spring tides.

Visibility is typically 3–10 m and falls after strong winds. Summer (December–March) air temperatures exceed 40 °C and cyclone season runs November–April. Irukandji and other jellyfish are possible in warmer months.

From the beach, surface-swim or kayak out across the channel with a flag to the reef edge 200–500 m offshore, then descend onto the bommies at 4–8 m. Work along the reef into the current if any is running so the return is assisted, holding 5–7 m around the large boulder corals. Turn at one-third air given the long swim home, make a safety stop on the reef and surface well clear of the channel before swimming back.

Mostly dived independently or snorkelled from the beach and kayak trail. Exmouth operators launch from Bundegi ramp and jet-ski snorkel tours visit the sanctuary zone; no regular scheduled scuba charter dedicated to the site.
