Strong current and surge conditions mean the site is recommended only for experienced divers. The site is only accessible from mid-March through the end of April, between the North-East and South-West monsoons; conditions turn hazardous outside that window. A separate 'iron wreck' about 4 km west of the reef has structure within roughly 2 feet (0.6 m) of the surface — a boat-strike and surfacing hazard for anyone diving nearby. The long boat transit (about 2 hrs each way) exposes divers to open-water swell.
