Diving at Gullivers (Australia)
In Lighthouse Bay on the northern tip of the Exmouth Peninsula, Gullivers is a boat-accessed coral reef dropping to about 14 m / 46 ft, with multiple outcrops full of life. Moray eels, lionfish, blue-spotted stingrays and blue groper all feature. Warm water and a mooring make it an accessible, rewarding reef dive for a range of divers when the northerly stays away.
Evening condition tracking at Gullivers features an air temperature of 20°C. We have recorded wave heights measuring 0.5 m during this period. These figures outline the environmental parameters currently present.
Dive Site Location & Key Facts
Dive Site Overview
Multiple coral outcrops rise from the reef here, each a knot of structure and life, with the whole site running to about 14 m / 46 ft and averaging closer to 12 m / 39 ft. It's a rich, busy reef in one of Exmouth's better-regarded spots.
The appeal is the sheer spread of life through the coral. Moray eels lurk in the holes, lionfish hang in the open with their fins fanned, blue-spotted stingrays rest on the sand, and blue groper patrol the bigger heads. Drifting up to a coral outcrop and finding a moray watching you from a crevice is the kind of moment the site delivers regularly. Access is by boat with a mooring available, which keeps the anchoring simple. Northerly winds influence the conditions, so the dive is best on a calmer day, but the moderate depth and easy terrain make it accessible to a wide range of divers. The outcrops give you natural waypoints, so you can move methodically from one to the next without losing your place. A mooring keeps the boat side simple, and the warm water lets you linger over each coral head.

Best Time to Dive
Autumn into early winter, roughly April through June, brings the best scores, and they stay strong almost year-round in this warm region. Water is genuinely warm, peaking near 28.6°C / 83°F and staying around 22°C / 72°F at its coolest, so light exposure protection works throughout. Wave height is very low, in a 0.6–0.9 m / 2–3 ft band, so swell is rarely the issue. The condition that matters is the wind, since northerlies influence the site, so a calmer day keeps the reef comfortable. With warm water and gentle seas lining up for much of the year, the main job is picking a day the wind cooperates. With warm water and low swell lining up for most of the year, the only real variable is finding a day the wind stays light.

Dive Experience & Conditions
Plan a boat dive over coral outcrops at about 14 m / 46 ft, moving outcrop to outcrop and reading each for its residents. The moderate depth keeps air and no-deco time comfortable, so the pace can be slow and thorough. A torch helps you peer into the coral holes where morays and other life shelter. Lionfish hang in the open, so admire them and keep your hands clear of their venomous spines. The reef terrain is easy to navigate, with the outcrops giving you natural waypoints, and the mooring keeps the boat side simple. Northerly winds shape the conditions, so a calmer day makes for the best visibility and the easiest diving across the outcrops. Work each outcrop slowly and the density of life rewards the patience.
Dive Difficulty & Safety Guidelines
No formal difficulty is recorded, but the moderate depth of about 14 m / 46 ft and easy reef terrain make this accessible to a wide range of divers, from comfortable open-water divers upward. The conditions are gentle most days, with low swell, so the main variable is the wind.
Lionfish are present, so enjoy them at a distance and avoid their venomous spines. Moray eels in the holes are best admired without poking around, since they'll bite if cornered. With no overhead and gentle terrain, the risks are minor and mostly about respecting the marine life. Pick a calmer day for the visibility, keep good buoyancy around the coral, and it stays a relaxed, rewarding reef dive.

This is a busy reef, and the confirmed list is long: moray eels in the holes, lionfish hanging in the open, blue-spotted stingrays on the sand, blue groper, snapper, angelfish and nudibranchs all work the coral outcrops.
