Giant trevally inhale their prey from 20 cm away through pure suction — the gill flare creates a vacuum that pulls bait into the mouth before the fish even closes the gap. That is why a stickbait worked with a sharp downward sweep, leaving a hole in the water surface, triggers them: the lure mimics a fleeing fish that just got vacuum-pulled.

Types of Trevally — how to identify them

Trevally is also known as: GT, Giant Trevally, Bigeye Trevally, Silver Trevally, Golden Trevally. From estuary silvers to offshore GTs — speed and brutality.

Regional names can confuse anglers and cause misidentification. The table of common names below covers the most-used alternatives across Australia, New Zealand and the US:

Key to correct identification: check the regulations-authority species sheet for your state or territory before keeping any fish — minimum legal sizes, bag limits and identification guides are published by each fisheries department and are the authoritative source.

Technique

GTs (giant trevally — tropical reefs): cast 180–250 mm stickbaits and poppers at reef edges, bommies and current lines on heavy popping rods (PE6–PE10). Walk the bait fast — they want to chase. Strikes are explosive surface eruptions; the take rate to landing rate is brutal because they live in nasty structure. Silvers (estuaries, NSW): light gear, small metals and plastics around schools busting on bait near wharves, breakwalls, and harbour markers.

Proven tackle & rigs

Field-proven Trevally methods compiled from published tackle guides — AU East and southern bays, estuaries, inshore reefs, wharves and bait schools. Every method links its source.

1berley-led light bait fishing

Bait / lure: pilchard, blue bait, mussel, prawn or other fresh oily bait

Rig: 1-3kg to 3-6kg light spin outfit, 2000-3000 reel, 6-10lb main line and roughly 6-12lb leader; fish in a steady berley trail

When & where: wharves, current edges, bay channels and reef edges where scent can hold schooling trevally near the boat or shore

Source →

2small soft-plastic casting

Bait / lure: 2-4in grub, curl-tail, worm, paddle-tail or minnow soft plastic

Rig: light spin tackle with jigheads around 1/12-1/4oz in 2/0-3/0, adjusted for current and depth; rig plastic straight

When & where: estuaries, piers, reefs and bay schools, especially when fish are feeding on small baitfish or worms

Source →

3micro-jigging workups and shallow reef

Bait / lure: small tungsten or metal micro jig around 14-28g

Rig: 2000-3000 size reel, light braid and a smooth drag set softly because trevally have soft mouths

When & where: autumn bait schools, bay workups, shallow reef and deeper low-lying reef where trevally are feeding through the water column

Source →

4small hardbody or metal search casting

Bait / lure: shallow-diving hardbody, small metal spoon or compact baitfish lure

Rig: light spin tackle with leader light enough for clear water but strong enough for pylons and reef edges

When & where: mobile schools in bays, canals and estuary mouths when a faster search bait is needed before switching to plastics or bait

Tide windows that matter

Current is the master variable for all trevally species. GTs hunt on current lines and the up-current side of reef structure — slack tide is dead, peak run is gold. In estuaries, silvers school heavily on the tide-change edges around wharf lights at night.

Moon & solunar

For GTs, the few days either side of the new moon often produce the biggest surface eruptions on tropical reefs — dark nights mean active hunting. Full moons can shut the day bite down (they've fed all night) and re-open it in the late afternoon. Estuary silvers are minimally moon-driven.

Regulations

Figures come from each jurisdiction's own fisheries authority, with the source linked on every page above. Rules change — closures in particular are reset annually — so confirm with the authority before you keep a fish.

Highly variable — "trevally" covers several species and each state treats them differently, often under a combined limit rather than a per-species one. The per-jurisdiction figures are above. Giant trevally are tag-and-release in most serious fisheries because of ciguatera risk and slow growth, regardless of what the bag limit technically permits.
