Coral Trout
Coral trout are the backbone of reef fishing across Queensland and northern Australia. Most anglers are chasing the common coral trout (Plectropomus leopardus), though four other species turn up regularly on the same reefs.
They eat well, they're catchable on a wide range of methods, and they live on the kind of hard reef country that makes for a great day on the water regardless of what else shows up.
Scientific Name: Plectropomus leopardus
Also known as Leopard coral grouper, leopard trout, common coral trout
- Vivid red-orange to olive-brown body covered in electric blue spots across the head, flanks, and fins — unmistakable on the reef.
- Heavy-shouldered build with a large mouth and visible canine teeth; built for grabbing baitfish off structure rather than chasing in open water.
- Typical fish run 40–70 cm and 3–6 kg; anything over 80 cm is genuinely large, and the species can exceed 20 kg, though fish above 8 kg are uncommon for recreational anglers.
- Five species are commonly caught in northern Australia — bar cheek, blue spot, passion fruit, coronation, and common coral trout — each with slightly different colouring and habitat preferences.
What to know
Habitat Distribution
- Native to Australian waters; found from Bundaberg in Queensland north and around the tropical coast, including the Great Barrier Reef, Coral Sea reefs, Ashmore and Cartier Islands, and Western Australia's Rowley Shoals and Scott Reef.
- Range extends as far south as Lord Howe Island in the Tasman Sea and has been recorded near Sydney, though productive fishing is concentrated in tropical and subtropical reef systems.
- Lives on coral-rich lagoon reefs, mid-shelf reefs, and any hard bottom with structure — inshore bommies out to offshore reef systems in 2–100 m of water, with most fishing effort between 10 and 80 m.
- Juveniles use shallow coral rubble and reef edges; adults move to deeper ledges, caves, and reef faces as they grow.
Key Locations
- Great Barrier Reef (Queensland) — the most extensive coral trout fishery in Australia, from Bundaberg north through Cairns and beyond.
- Hervey Bay offshore reefs — ledge country in the 30 m range is a well-known local hotspot, with the 100 ft depth band particularly productive.
- Lucinda and the reef known locally as "Trout Alley" (~28 miles offshore) — a named destination for dedicated coral trout anglers in north Queensland.
- Rowley Shoals and Scott Reef (Western Australia) — remote offshore reef systems that hold coral trout in good numbers for those who can access them.
- Ashmore and Cartier Islands (Timor Sea) — part of the species' Australian range, targeted by liveaboard and charter operations.
Specific Spots
- Ledge country is the prime address — fish hold right at the top of a ledge where it peaks before dropping away, or on the first few metres of the face itself.
- Caves, undercuts, and holes in the reef give coral trout a bolt-hole; they sit close to cover and dart out to take prey, so presentations that land near the structure edge outperform those drifted over open sand.
- Bommie edges and reef tops in 10–20 m where sunlight penetrates are productive for shallower fish, especially earlier in the day.
- When sounding a new area, work the perimeter of a ledge to find its high points and steepest sections — those features concentrate fish far more reliably than flat reef country.
Coral Trout FAQ
Answers from onWater's species guide.
What are the best lures and bait for Coral Trout?
Hard-bodied minnow lures (bibbed and bibless) cast or trolled over reef structure are a proven approach, match the size to local baitfish, typically 90–130 mm, in natural or bright colours depending on water clarity.
When is the best time to fish for Coral Trout?
Coral trout can be caught year-round across their range, with no strong seasonal shutdown outside of regulated closures. Queensland's coral finfish closures apply during spawning periods, check the current Queensland Department of Agriculture and Fisheries rules for exact dates before planning a trip.
How do you catch Coral Trout?
Most anglers target coral trout from a boat, either drifting or anchored over hard reef structure. The standard approach is to sound out ledges carefully before fishing, identifying the high points and steep faces, then position the boat to work lures or baits along the structure edge rather than over open bottom.
What do Coral Trout eat?
Adults feed almost entirely on fish, small reef fish, baitfish schooling near structure, and anything that wanders too close to cover. This is why hard-bodied minnow lures and soft plastics rigged to look like a fleeing baitfish are the go-to presentations.
Where do Coral Trout live?
Native to Australian waters; found from Bundaberg in Queensland north and around the tropical coast, including the Great Barrier Reef, Coral Sea reefs, Ashmore and Cartier Islands, and Western Australia's Rowley Shoals and Scott Reef.
