Barrier Reef coral harvest probe

Highlights

FishNet data shows Pocillopora grandis catches in the 2025-2026 season exceeded quota by 30 per cent, triggering a Fisheries Queensland internal investigation.
A 2024 assessment highlights ongoing quota overruns and flags potential regulatory changes including trip limits, increased notifications, and shifting more species to individual quotas.
Repeated breaches and compliance issues add regulatory risk as conservationists question reef trade controls, with penalties including a $250,000 fine for Monsoon Aquatics in 2024.

Quota breach and investigation details

As first reported by ABC News, Fisheries Queensland says it recently investigated an overharvesting event involving Pocillopora grandis, or antler coral, on the Great Barrier Reef. FishNet data shows catches of the species in the 2025-2026 fishing season exceeded quota by 30 per cent, while the agency declines to disclose the outcome of its internal investigation.

Coral harvesters are permitted to take up to 190 tonnes from the reef each year, with much of the material destined for the global aquarium trade. The fishery operates with two quota systems, individual transferrable quotas and prescribed commercial catch quotas, with the latter allowing operators to compete until a species limit is exhausted.

Fisheries Queensland says overruns under the competitive quota model are not uncommon or unreasonable. A 2024 assessment of the Queensland coral fishery says some species continue to exceed catch limits despite management efforts, and flags possible measures including trip limits, increased notifications and a broader shift to individual quotas if the problem persists.

Industry compliance and sustainability concerns

Scientists and conservation groups say the latest breach adds to wider concerns about whether current controls are adequate for a reef already under environmental stress. Coral reef ecologist Dr Morgan Pratchett says the species involved is not currently under threat, but argues any overharvesting sends a poor signal amid heavy international scrutiny of the industry's management.

Simon Miller of the Australian Marine Conservation Society says repeated quota overruns suggest precautionary limits may be set too high or enforced too weakly. Several Australian coral species are already barred from import into the EU on sustainability grounds, adding trade sensitivity to the regulatory debate.

The sector has also faced broader compliance problems in recent years. A case pursued by the Queensland Director of Public Prosecutions involves coral collector Jardini and its director Jason Coe, who holds five licences in the Queensland coral fishery and has not yet entered a plea, while Monsoon Aquatics lead diver and skipper Tim Green was earlier in 2024 found guilty and fined almost a quarter of a million dollars over offences tied to coral and fish collection in Western Australia.

Monsoon director Daniel Kimberley says the company supports stronger compliance and better monitoring, and adds that the fishery is looking at moving more species into individual quota settings. He argues the Great Barrier Reef's scale means the industry's footprint remains relatively small, but critics say weak data and cumulative reef disturbances leave little margin for repeated quota breaches.

Our earlier article on Menara Asia’s Menarabena launch looked at how Malaysia’s construction sector is using digital tools to strengthen compliance and quality control in building-material procurement. We outlined how the platform links contractors with suppliers while centralising certification, technical documentation and regulator requirements, alongside CIDB-related initiatives aimed at standardising approvals and improving supply-chain transparency.
