Red Emperor
Offshore / ReefDeep-water tropical snapper and one of the most prized demersal fish in northern WA. Found from the Abrolhos northward, but the recreational fishery is centred on the Gascoyne and North Coast bioregions in 40–120m of water. Slow-growing, long-lived, and managed within tight mixed-bag rules.
Overview
Red emperor are the trophy demersal of WA's tropical north — deep-bodied, vivid red, and a fish that grows slowly enough that big breeders are decades old. They live on rubble and broken bottom in 40–120m, often holding alongside spangled emperor, rankin cod and tropical snappers. The Gascoyne and North Coast bioregions hold the bulk of the recreational catch; south of Kalbarri they're a rare bycatch. Because they're slow-growing and breed at size, the bag rules are conservative and barotrauma management matters — release tools and weighted releasers are standard kit.
Identification
Red, reddies, government bream
Deep-bodied, steep-headed crimson snapper with a large eye. Young and mid-sized fish carry three broad dark red-brown bands — one through the eye, one running diagonally from the dorsal down to the pelvic fins, and one across the rear of the body into the tail — and those bands fade with age until a big red is close to solid deep crimson. That banding is the separator from the other tropical reds: crimson snapper and saddletail are more uniformly coloured, more streamlined and smaller-eyed. Small banded fish have been called government bream in the north for generations.
How to Catch
Whole squid, butterflied mullet, slimy mackerel fillet, octopus strips, large pilchards
Slow-pitch jigs 150–300g, large soft plastics on heavy jigheads, vertical knife jigs
Paternoster rig with two 8/0–10/0 circle hooks on heavy droppers and an 80–100lb mono leader. Use enough sinker — typically 16–32oz — to hold bottom in deep water and current. Some anglers run a snelled twin-hook on a single dropper for big baits. Strong knots, sharp hooks, and quality terminals are essential at depth.
Drift or lightly anchor over rubble and reef edges in 40–120m, dropping baits to the bottom and winding two cranks up. Reds favour the corners of reef structure rather than the peaks. Slow-pitch jigging works well when fish are aggressive — short, sharp lifts off the bottom. When you find a school, mark the spot and work it methodically. Use a release weight for any fish you're not keeping; barotrauma is real at depth.
Northern WA fishes year-round, with the cooler months (May–September) offering the best weather windows in the Gascoyne and Pilbara. Tide changes trigger the bite; neap tides make bottom-fishing easier than springs. Dawn and dusk are most productive.

Size & Growth
Most northern WA reds are 4–10 kg. A good fish is 8–12 kg, and a 15 kg-plus red is a trip highlight rather than a session. Twenty kilos is the practical maximum. The 45 cm minimum equates to roughly a 2 kg fish, so plenty of legal reds are small. What matters is the growth rate: red emperor are very slow-growing and live for decades, so a big breeder is genuinely old and cannot be replaced quickly. That is the whole logic of the two-fish bag limit, and of carrying a release weight for everything you are not keeping.
Diet & Habitat
Reds work the bottom for crustaceans, cephalopods and small fish, and they favour the edges and corners of structure rather than the peaks. Look for rubble, broken bottom and reef margins in 40–120 m, often alongside spangled emperor, rankin cod and the tropical snappers. Juveniles live inshore in shallower, more turbid water, including mangrove-fringed bays, before moving out to deep reef as they grow. The recreational fishery sits in the Gascoyne and North Coast bioregions — Exmouth, Onslow, Dampier, Broome — with fish present as far south as the Abrolhos but only as a rarity below Kalbarri.

Minimum size: 450mm. Bag limit: 2, within the demersal scalefish mixed daily bag of 4 in the Gascoyne and North Coast bioregions where it lives. Red emperor are a northern fishery; note a boat-based demersal closure applies in the West Coast Bioregion (Kalbarri to Augusta) until at least September 2027.
Eating Quality
Yes — a premium WA table fish and the headline esky-filler of any northern demersal trip. The fillets are thick, firm and white with a very mild flavour and a large flake, and they hold together on a grill, in a curry, or in batter better than most. Bleed and ice the moment it is aboard; the flesh deteriorates faster than it looks in tropical heat. The wings, cheeks and roe are all worth keeping — wings crisped on a barbecue plate are arguably the best part of the fish. Big fish hold quality as well as small ones here, which is not true of every species. It also freezes better than most: vac-sealed fillets keep two or three months without much loss.
Perth Tips
Charters out of Exmouth, Onslow, Dampier and Broome target reds as a headline species. Inshore reefs around the Mackerel and Montebello Islands hold them in summer. Common rookie mistakes are using gear too light for the depth, and not having a release weight on board — you'll need one for undersized fish or a full bag.
