Joanie's Joy is a relaxed wall and bommie dive on the Ribbon Reefs, listed by Spirit of Freedom with a depth range of 30 m to 3 m. The reef wall runs down from a shallow top, and a scatter of bommies sits off its base, which lets divers design a dive to their own taste: follow the wall, hop between bommies, or combine the two.

The operator's species list is typical of a healthy lagoon-side Ribbon Reef site: anemones with their resident anemonefish, cuttlefish, nudibranchs, sweetlips, whitetip reef sharks, trumpetfish, lionfish and turtles. The bommies concentrate fish, and the wall face offers overhangs where lionfish and sweetlips shelter during the day. Cuttlefish often hover near the reef top, and whitetips rest on sand patches between the bommies.

Because the site covers the whole recreational depth range without strong current, it suits divers of every level, from those on their first liveaboard to photographers wanting a long, unhurried dive. It is a good choice for an afternoon dive after deeper morning pinnacles, as most of the interest lies in the top 15 m.

The reef number is not stated in the published description, so the coordinates in this record are an estimate. The name follows the Ribbon Reef tradition of naming moorings after crew or guests, as at Steve's Bommie and Andy's Postcard. Divers should expect conditions typical of the central Ribbons, with visibility of 15–30 m and a mild current. Night dives are possible from the mooring when the boat stays overnight, and the bommies then come alive with feeding crustaceans and hunting lionfish.

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 Joanie's Joy on Spirit of Freedom trips.

Divers enter by giant stride from the dive deck at the mooring and descend the mooring line. The wall and bommies are dived from a mooring; the crew briefs whether to follow the wall or explore the outlying bommies.

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.

Descend to 15–20 m at the base of the wall, follow it to the scattered bommies, circle one or two, then return along the wall at a shallower depth and finish at 3–5 m on the reef top for the safety stop.
