# Curtin Artificial Reef

Curtin Artificial Reef sits in Moreton Bay, around 30 kilometres east of Brisbane, in 12 to 30 metres of water. Built by the Underwater Research Group of Queensland from 12 August 1968 onward, the reef has been added to in waves over more than three decades. The result is one of Australia's oldest planned artificial reef systems, covering roughly 400 by 120 metres of seabed and now the standout advanced-level dive in south-east Queensland's bay waters.

## How the reef came to be

The Underwater Research Group of Queensland (URGQ) started sinking vessels in the bay in 1968, naming the project after Frank Curtin in recognition of his work organising the donations, the cleanups, and the regulatory approvals that made the scuttlings possible. The group spent three decades acquiring, stripping, and sinking a remarkable spread of vessels, from small craft through to coastal traders and industrial barges.

The roll call includes the tug Melbourne, the whale chasers Kos I and Kos II, the coastal trader Lady Norman, the gravel barges Bremer, Estrella del Mar, and Barrambin, the car ferry Point Lookout, the whale oil carrier Centipede, the tug Lovenstein, and the Cairncross dock gate. A Brisbane tram was also added at one point. Smaller infill came from pontoons, buoys, car bodies, and tyres in the early decades, before the project shifted toward larger and more substantial pieces.

The site has been down long enough now, more than fifty years on the oldest sections, that the wrecks have stitched themselves into a continuous artificial reef rather than a scatter of individual structures. Coral, sponge, and ascidian growth has overtaken much of the original metalwork, and the ocean has reclaimed parts of the older vessels entirely.

## The dive

Most dives start in the deeper twenty to twenty-seven metre range on one of the more substantial wrecks, work along the structure to a smaller piece of the reef, and finish on safety stops in the shallower section. The reef rewards multiple visits: with this much wreckage spread across this much area, no single dive covers the whole site.

Penetration is possible on some of the larger vessels, but should only be attempted by divers with the right wreck training. The wrecks have been down long enough that interior structure is unpredictable, with collapsed plating, silt-out potential, and entanglement hazards in the cabling and rigging that has accumulated over decades.

Buoyancy control matters here more than at most sites. The wrecks have grown delicate growth that takes years to recover from a careless fin kick or a dropped gauge.

## Marine life

Decades of unbroken protection have turned the reef into one of the better fish-stock dives in south-east Queensland. Resident populations include large Queensland groper hanging close to the wreckage, often within touching distance of a careful diver, and schools of yellowtail kingfish that hunt the perimeter in tight formation. Wobbegongs sleep in the lee of the bigger structures, and brown-banded bamboo sharks tuck into the smaller crevices.

Eagle rays and bull rays cruise the sand between wrecks. In winter, schooling barracuda are reliable in the water column above the structure, sometimes in the hundreds. Octopus, lionfish, scorpionfish, and the full range of east-coast reef fish round out the supporting cast.

The fishing pressure is heavy on the surrounding bay but largely absent on the reef itself, which has been recognised as a no-take zone for divers and a contested space with line fishers over the years. The fish-stock difference between the reef and the surrounding bay tells the story of what protection delivers when given enough time.

## Conditions and safety

The site is exposed and currents can be strong, especially around the change of tide. Most operators check the tide chart and dive on slack or near-slack water. Surface marker buoys are mandatory, and divers should be confident with a free ascent in case of unexpected current at depth.

The advanced rating exists for good reason: the depth, the current exposure, the size of the site, and the wreck-penetration temptations all reward divers who know what they are doing. Recreational depth limits apply, and there is no benefit to pushing past twenty-seven metres on the deeper structures since the marine life is concentrated in the shallower sections.

## Getting there and facilities

Access is by charter from Brisbane or the northern bayside suburbs. Most operators run day trips with two dives at the reef and surface intervals on board. Air fills, basic facilities, and toilet stops are at the marina end rather than at sea, so plan accordingly. Check the operator's permit and conservation policy before booking, since the reef has been damaged in the past by careless visitors and the dive community in Brisbane is rightly protective of it.

## Gear and photography notes

The current exposure and the depth make a surface marker buoy non-negotiable. A delayed-deploy SMB is the standard answer, since the boat will often drift well off the dive site by the time the group surfaces. A primary torch is useful even on bright days, since the larger wrecks have sheltered sections that go dim quickly, and a backup light is sensible for any diver considering even shallow penetration.

For photography, the reef rewards both ends of the lens spectrum. Wide-angle is the obvious choice for the wreck silhouettes and for the schools of barracuda and kingfish working the water column above. Macro setups have plenty to find on the encrusted growth, particularly nudibranchs, small crustaceans, and the juvenile fish that shelter in the broken plating. Mid-water visibility is rarely good enough to rely on natural light at depth, so strobes or video lights earn their keep.

Penetration photography is its own discipline. If the dive plan includes any wreck interior, treat it as a wreck-specialty dive in its own right, with the appropriate training, redundant gas, and a line and reel.

## Combining with nearby sites

Curtin sits among a cluster of Moreton Bay wreck and reef sites that work well as a multi-day plan. Most charter operators rotate between Curtin and the other artificial reefs in the bay, including the Harry Atkinson, West Peel, and the various Peel Island sites. A weekend trip can comfortably take in three or four sites without revisiting the same wreck twice.

For divers travelling specifically for wrecks, combining a Curtin trip with the Tangalooma Wrecks on the western side of Moreton Island makes for a contrasted weekend: Tangalooma is shallow shore-accessible diving on a deliberate breakwater of beached vessels, while Curtin is the deeper, current-exposed offshore counterpart. Together they cover the spectrum of artificial-reef diving in south-east Queensland.

## Final notes

Curtin Artificial Reef is a piece of Brisbane diving history that has aged into a genuine ecosystem. For local divers it is a regular fixture, and for visitors it is a strong advanced-level wreck and reef combination that justifies its slot in any south-east Queensland dive plan. Plan multiple visits if you can: with fifty years of wreckage spread across four hundred metres of bay, there is more here than any single dive can cover.
