About Whaler Station (Flinders Reef)
Whaler Station is listed by marinelife.org.au as a related site to China Wall on Boomerang Reef, in the Flinders group, together with Cod Wall. No description of its own was found in the sources consulted.
The name is suggestive. 'Whaler' is the Australian name for several requiem sharks of the genus Carcharhinus, including bronze, dusky and bull whalers, and a 'station' may refer to a cleaning station or a spot where the sharks congregate. Alternatively, the name may commemorate nineteenth-century whaling in the Coral Sea; whalers were among the ships lost on Coral Sea reefs, including the Jane and Lion on Wreck Reef in 1856. Neither explanation is confirmed.
Given its association with China Wall, a wall that drops to about 1,000 m with gorgonian fans up to 4.5 m across, black coral trees, sea whips, sharks and pelagic fish, Whaler Station is probably also a wall site. The general fauna of the Flinders area applies: grey reef, whitetip and silvertip sharks, reports of tiger and tawny nurse sharks, yellowfin and dogtooth tuna, trevally and barracuda, with soft corals and fans on the walls and visibility often above 40 m.
This record is provisional and should be expanded when details become available. It is likely dived only occasionally, if at all, on current itineraries. Divers on a Flinders expedition should ask the crew whether it is used and what to expect, and should plan for a deep wall with the usual attention to depth and gas, given how far the site is from any medical help.
Getting there & entry
A site related to China Wall on Boomerang Reef in the Flinders group, listed by marinelife.org.au; layout and position not published.
Liveaboard only, from Townsville. Mike Ball's Spoilsport visits Flinders on its 7-night Yongala & Coral Sea expedition (depart Breakwater Marina, Townsville, Thursday evening, finish in Cairns) and the 10-night Coral Sea Odyssey; the overnight crossing is about 140 nautical miles (260 km), passing Myrmidon Reef on the outer Great Barrier Reef. Private expedition yachts anchor behind the main sand cay in about 30 m over sand.
Whaler Station is listed by marinelife.org.au as a related site to China Wall; it would be dived from a mooring or tender drop.
Entry: Giant stride from liveaboard dive deck; descend mooring or line
Weather, swell & tides
The Flinders Reefs lie about 250 km off the Queensland coast, roughly 140 nautical miles north-east of Townsville, beyond the outer Great Barrier Reef. The crossing is made overnight through open ocean and is uncomfortable in SE trades over about 20 knots (common June–August). The main sand cay gives some shelter from the trades, and the lagoon pinnacles are more protected than the outer walls.
Currents can be strong through the reef gaps and over the mid-reef bommies. September–December usually gives the calmest seas and 40 m-plus visibility; December–April is cyclone season.
Best season: Year-round when weather allows; Sep–Dec usually calmest and clearest (visibility can exceed 40 m); Jun–Aug stronger SE trades make the open-ocean crossing rough; Dec–Apr cyclone season
How the dive is usually run
No published dive plan. Follow the crew briefing; expect a wall dive with depth monitoring and an ascent along the wall.

Diving in Coral Sea
Beyond the outer Great Barrier Reef the continental shelf drops away and a scatter of isolated oceanic reefs rises from 1,000 m or more of water. Osprey, Bougainville, Holmes, Flinders and Lihou reefs have vertical walls, 40 m-plus visibility, and shark populations that were never fished down. North Horn at Osprey is the best-known shark dive in Australia; the southern reefs are visited by a handful of boats a year.
Getting there: Liveaboard only, 4–7 nights from Cairns or Port Douglas for Osprey and the northern reefs; expedition trips from Cairns or Townsville for Flinders and Lihou. Overnight crossings of open sea are part of the deal.
