Circle of Life is a southern Ribbon Reef mooring shown on Mike Ball Dive Expeditions' Cod Hole–Ribbon Reefs itinerary map, grouped with Steve's Bommie, Flare Point, Blue Lagoon and Fish Market. Like several moorings on that map, it has no published site description in the operator's guides or the other sources consulted, so its depth, layout and highlights are not documented. It should not be confused with the Circle of Life Memorial Reef, an artificial memorial reef project elsewhere, which is unrelated.

The name hints at a ring-shaped reef or bommie cluster, or perhaps a site where a full cross-section of reef life can be seen in one dive. On the southern Ribbons, reef types range from shallow Acropora gardens (Flare Point, Summer Bay) to isolated pinnacles with schooling fish (Steve's Bommie, Temple of Doom), so the site could be either. Divers can expect the general fauna of the area: anthias and chromis over the coral, fusiliers, snapper and trevally, sweetlips and groupers, whitetip reef sharks, turtles, cuttlefish and a good range of nudibranchs and small crustaceans.

Conditions match the rest of the southern Ribbons, with 15–30 m visibility, mostly gentle currents on the lagoon side, and dwarf minke whales around Ribbon Reef No. 3 in June and July.

This record is provisional. Ask the cruise director for the route and depth if it appears on the day's plan, and update the entry when better information is available. For planning purposes, treat it as an occasional alternative mooring rather than a headline site, and keep the usual margins on depth and gas until the profile is known.

Liveaboard only (or fly-dive via Lizard Island). Mike Ball Dive Expeditions' Spoilsport and Spirit of Freedom depart Cairns (Trinity Wharf / Marlin Marina) in the evening and steam north overnight, roughly 12–14 hours and 200–250 km, to reach the Ribbon Reefs by morning; some itineraries fly Cairns–Lizard Island (about one hour, scenic flight along the coast) and board or disembark there. Trips run 3–7 nights and include Circle of Life occasionally.

Divers enter by giant stride from the dive deck at the mooring and descend the mooring line. It is listed on Mike Ball's itinerary map in the southern group with Steve's Bommie, Flare Point, Fish Market and Blue Lagoon and is used at the crew's discretion.

The Ribbon Reefs sit on the edge of the continental shelf and take the full south-east trade wind from April to October. Lagoon-side moorings stay diveable in 20–25 knot SE winds, but reef-front sites and passes need lighter winds; liveaboards shelter behind the reefs overnight. September to December is usually calmest.

Tidal flow through the gaps between the Ribbons is strong on springs, so exposed pinnacles are timed for slack water. December to April brings rain, lower visibility and cyclone risk; box jellyfish and Irukandji are possible November to May.

No published dive plan. Expect a moored reef dive: descend the line, follow the crew briefing, turn at half gas and finish with a safety stop on the reef top.
