A boat operation is the practical access model described in the source text; local guidance is advisable for site approach and conditions.
Lighthouse Bommie is a compact reef pinnacle with a steep, central profile and a clearly defined swim-around route. The bommie is heavily covered in marine growth, with stronger color and life closer to the top and more macro interest lower on the structure. Divers may see mantis shrimp near the base, along with general reef fauna across the bommie. It is best planned as a boat-accessed reef dive where conditions can shape how easy the circuit feels.
Depth range, seasonality, and planning context.
Reported Depth
3m - 25.9m

Sources describe a shallow crest and a deeper sandy base, with the profile varying a little between references.
Best Season
Dry-season months are the most commonly suggested window, with the clearest conditions often described in the middle of the year.
Typical Conditions
A compact coral-covered bommie with good reef life, a shallow top, and a deeper base. Conditions are often described as suitable for a circuit-style dive, with visibility and current varying by day.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Plan for open-water conditions around an isolated bommie and stay aware of current, spacing, and ascent control. Divers should keep track of the reef profile and avoid pushing beyond comfort if the current picks up.
Community notes to help plan your visit.
Scuba
Best suited to a relaxed circuit around the bommie, with attention to the shallower crest and the deeper base where macro life may appear. The site is commonly described as rewarding for both structure and marine life.
Freedive
The bommie profile gives freedivers a compact feature to work around, but the open-water setting means current and surface control matter. Conservative breath-hold planning is recommended.
Snorkel
The shallow crest may offer snorkel interest when conditions are calm, but this is still an exposed reef feature rather than a sheltered beach snorkel. Snorkelers should only consider it in suitable weather and with support.
Chill / Non-diver
Not a dedicated chill site; the main appeal is the reef structure and marine life rather than shore-side hanging out.
