Fish Town is one of the eleven named moorings on Milln Reef and one of the five Milln sites Pro Dive Cairns features for its liveaboard, alongside Whale Bommie, Petaj and the two Swimming Pools. The name is the best clue to its character: it is a site where fish congregate, and dives here tend to be remembered for the sheer numbers of schooling fish rather than for dramatic topography. Pro Dive Cairns describes Milln as a reef of wall dives, pinnacles and swim-throughs with depths of 5-25 m, mild currents and 15-20 m visibility, and Fish Town fits that pattern, with coral bommies rising from the reef slope.

Operators and dive guides mention Milln's schools of sweetlips, fusiliers and snapper, turtles and whitetip reef sharks, and Fish Town is a good place to see all of these. At cleaning stations on the bommies, coral trout, groupers and sweetlips queue for attention from cleaner wrasse, and batfish often hang near the mooring. At night, as elsewhere on Milln, sleeping parrotfish in their mucus sacs, turtles and hunting barracuda are the main attractions.

Because specific published descriptions of this mooring are brief, the details here are drawn from operator summaries of Milln Reef as a whole; divers should rely on the day's briefing for the exact route. It suits divers of all levels and makes a good second or third dive. Visibility is typically 15-20 m, and the fish schools tend to be densest when a gentle current is running across the reef.

Photographers should bring a wide lens for the schools and be ready for close passes from curious batfish.

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.

Fish Town is listed by Pro Dive Cairns and Cairns Dive Adventures among the Milln moorings; it is used on liveaboard itineraries and by day boats. 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. Fish Town is one of the Milln moorings used in moderate south-easterlies; published detail on its exposure is limited.

Descend the mooring and follow the guide's route around the main bommies at 10-18 m, spending time on the cleaning stations and schooling fish. Return over the shallower reef and complete a safety stop at 5 m.

Pro Dive Cairns – liveaboard; Silverswift – occasional day-trip mooring; 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
