About East Meets West (Thetford Reef)
East Meets West is one of the newer moorings on the Cairns outer reef, added by Passions of Paradise in 2016 at the eastern end of Thetford Reef. Its name reflects its structure: along this section the reef changes from a solid wall into a scatter of small bommies, so a single dive takes in both types of terrain. The operator describes it as protected from summer northerly winds and suitable for calm-water snorkelling and diving, and that is its role on the Passions roster, alongside sites such as Point Break on Flynn and The Drop on Milln.
The wall section is covered in hard corals with anemones and soft corals, and the transition zone where it breaks up is often the most productive part of the dive, as fish use the gaps and small bommies for shelter. Expect schools of fusiliers and damsels, parrotfish, wrasse, butterflyfish and angelfish on the coral, coral trout and cod under ledges, and turtles and reef sharks passing along the edge. Thetford's giant clams, stingrays and moray eels may also be seen.
The depth is modest and there is usually little current, so the site suits divers of all levels and makes a good snorkelling stop for non-divers on the same boat. Because it was established relatively recently and is used only in particular conditions, published detail is thin and depth figures here are estimates based on the operator's description. The site gives the operator a sheltered option on summer days when many of the traditional south-east-sheltered moorings are choppy, and it tends to be uncrowded.
Getting there & entry
Passions of Paradise mooring added in 2016 at the eastern end of Thetford Reef, about 45 km east-south-east of Cairns, where a solid wall breaks up into small bommies.
Boat access only. Cairns day boats leave from the Reef Fleet Terminal (1 Spence Street) and the neighbouring Marlin Marina on the city waterfront, with check-in between about 7:00 and 8:00 am; most operators run transfers from city and northern-beaches accommodation, and there is paid parking near the terminal. The run of about 45 km out through Trinity Inlet and across the lagoon to Thetford Reef takes around 80 minutes on a fast catamaran and noticeably longer on slower dive boats or into a south-easterly chop.
East Meets West is a Passions of Paradise mooring used in summer northerlies. Enter from the stern steps.
Entry: Giant stride or back-roll from the dive deck; descend the mooring line or reef slope
Facilities: Departs Reef Fleet Terminal / Marlin Marina, Cairns: toilets, cafes, paid parking; dive gear, tanks and lunch supplied on board
Weather, swell & tides
The prevailing south-east trade winds (typically 15-25 knots from April to September) are what limit Cairns outer-reef diving: above about 25 knots trips may be cancelled, and exposed eastern moorings are used only in light winds. Summer northerlies are gentler but make north-facing moorings choppy. Box jellyfish and Irukandji are present from about November to May (stinger suits on every dive), and the cyclone season runs November to April, when a system in the Coral Sea can close the reef for days.
Visibility drops after heavy rain and strong winds; spring is usually calmest and clearest. East Meets West gives protection from summer northerly winds and is therefore used mainly from October to March; it is less suitable in strong south-easterlies.
Best season: Year-round. June-November gives the most reliable visibility and no box-jellyfish season, though the south-east trades can blow 20-25 knots in winter; September-December usually has the calmest seas; December-April is the warm, wet stinger and cyclone season
