The world's largest coral-reef system: GBRMPA zoning, a 1981 UNESCO listing, and snorkel pontoons that sit beside wrecks like the Yongala. The Great Barrier Reef is a coral province off Queensland, managed as the Great Barrier Reef Marine Park since 1975 and inscribed by UNESCO in 1981.
Wow factor is at the top of this atlas. Seasonality is high because of the summer stinger (box-jellyfish) window, cyclone risk and the difference between a calm cay and a Coral Sea wall. Accessibility is middling: Cairns and the Whitsundays run day boats; outer ribbon reefs and the Yongala are longer, weather-bound trips.
Check each criteria to confirm findings against the atlas verdict.

This chapter is a place atlas, not a certifying agency, not medical advice, and not a live briefing. Zoning, stinger suits and the day's wind override any sentence here. A Queensland coastal window, often November to May, when box jellyfish and Irukandji risk rises. Many beaches fly stinger nets; reef pontoons issue full-body lycra. This is not a medical protocol.
SS Yongala sank in 1911 off Cape Bowling Green and is dived as a protected historic wreck in GBR waters, typically as an exterior. See wreck-diving. Ribbon Reefs (including Cod Hole) are outer-shelf walls, usually liveaboard or long day boats. Pontoons at Agincourt, Hardy and similar sites are the mass snorkel product.
