Round the Bend, also written Around the Bend, is one of the eleven named sites on Milln Reef listed by Cairns Dive Adventures and one of three Milln highlights named by Dive the World, alongside Wildside and Three Sisters. Beyond its name, which refers to a curve in the reef edge, there is little site-specific published information, so this description draws on what operators report for Milln Reef generally. Milln is a reef of large bommies rising from sand at around 30 m to within a few metres of the surface, with walls, pinnacles and swim-throughs, mild to medium currents and visibility typically 15-20 m.

A bend in the reef edge like this usually concentrates current flow, which means healthier coral on the outer curve and more fish working the edge. Expect whitetip reef sharks, turtles, coral trout, peacock groupers and schools of sweetlips, the fish Milln is best known for, along with nudibranchs, flatworms, moray eels, sea stars and painted lobsters on the reef. Dolphins are occasionally reported on Milln and reef squid hover over the shallows.

The site is suitable for Open Water divers if the current is mild, and more interesting for those comfortable following a reef edge. Divers should treat it as a less-documented site and rely on the briefing for the exact layout and route. It is a useful alternative when the main Milln moorings are occupied by other boats.

Snorkellers can explore the reef crest in calm weather, but the main interest is on the edge itself at 10 m and below.

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 55 km out through Trinity Inlet and across the lagoon to Milln Reef takes around 76 minutes on a fast catamaran and noticeably longer on slower dive boats or into a south-easterly chop.

Round the Bend is one of the Milln sites listed by Cairns Dive Adventures and Dive the World; it is used occasionally by Silverswift and on liveaboard itineraries. Enter from the stern platform.

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. Published detail on its exposure is limited; like other Milln sites it is chosen according to the day's wind.

Descend the mooring and follow the reef edge around the bend at 12-18 m with the reef on one side, turning at a third of your gas and returning shallower. Safety stop over the reef top.

Silverswift and Pro Dive Cairns – occasional; Milln is also worked daily by Silverswift and Passions of Paradise and on Pro Dive Cairns liveaboards; the mooring used on any day is chosen by the skipper according to wind, tide and other boats
