Olive Point is the northern tip of Middle Island, a small national park island close to Great Keppel, and it offers a shallow coral garden dive that complements the old observatory site on the island's southern side. The site takes its name from the olive sea snakes that are seen here regularly and that are, as the local guides point out, harmless unless harassed. The coral gardens extend from the shoreline down to about 8 m, with a mix of branching, plate and massive corals interspersed with sand channels.

Reef fish are plentiful, including damsels, wrasse, parrotfish and butterflyfish, and turtles are often seen resting on the bottom or feeding along the reef edge. The site is simple to navigate and stays shallow, making it well suited to new divers, refresher dives and snorkellers, and to long, relaxed dives with plenty of light for photography. Sea snakes will often approach divers out of curiosity, rising to look at their masks before returning to the bottom; the best approach is to keep still and let them lose interest.

Olive Point is not one of the Keppels' showpiece dives, but it is a dependable reef in sheltered conditions and a good place to become comfortable with the region's snakes before visiting sites such as Egg Rock or Half Tide Rock, where they are also common. Divers who want a longer day can combine Olive Point with the observatory site on the opposite side of the island, since both are only minutes apart by boat and the two reefs show slightly different coral communities. The site also works as a snorkel from the boat on calm, clear days.

Drive 40 km (about 40 minutes) from Rockhampton to Yeppoon, then 7 km south along the Scenic Highway to Keppel Bay Marina at Rosslyn Bay Harbour, where there is free and paid parking. Freedom Fast Cats and Keppel Konnections ferries run to Great Keppel Island (Fisherman's Beach) in about 30 minutes; Keppel Dive & Water Sports picks up certified divers from the island. Olive Point is on the northern side of Middle Island, about 10 minutes by dive boat from Fisherman's Beach or 30 minutes by private boat from Rosslyn Bay.

Boats anchor on the sand off the point, clear of the coral.

Keppel Bay is exposed to the prevailing south-east trades (strongest April-September) and to summer northerlies. The northern side of Middle Island is sheltered in south-easterlies but exposed to northerly winds, which are common on spring and summer afternoons. Currents are usually light around the point.

Visibility 5-12 m, lower after rain and strong winds.

Descend on the sand off the point at 6-8 m and follow the coral garden along the shore with the reef on one side, turning at half air and returning slightly shallower. Safety stop over the coral in 4-5 m.

Keppel Dive & Water Sports (PADI 5 Star, based on the Spit at Great Keppel Island next to Great Keppel Island Hideaway) runs guided boat dives to the Keppel sites most days, weather permitting, plus courses and Discover Scuba; site choice is made on the day according to wind. Private boats from Rosslyn Bay also dive here. Used as an easy coral garden dive and snorkel.
