Plan your dive around the tidal cycle rather than just the time of day, as the current through the cave system is directly tied to tidal movement and can shift from manageable to genuinely challenging. The site dives best between May and September when conditions tend to be most settled.
Access is via a short boat ride (approximately 10 minutes) from the Lady Elliot Island Eco Resort. All dives are guided and operated by the resort's dive shop. Shore diving is not permitted at this site.
