The Complete
Yellowtail Kingfish
Guide

About the Species

Yellowtail kingfish (Seriola lalandi) — known as kingfish, kings, or hoodlums — are one of Australia's premier inshore and offshore sportfish.

Found along the entire east coast of Australia from Queensland to Tasmania, with highest concentrations in NSW, South Australia and Victoria. The same species known as yellowtail amberjack in California, and hiramasa in Japan — where they are prized as one of the finest fish for sashimi.

Behaviour & Habitat

Highly visual, opportunistic predators feeding on yellowtail (yakkas), slimy mackerel, garfish, squid, anchovies and jelly prawns. Strongly associated with structure — rocky reefs, pinnacles, channel markers, navigation buoys, bridge pylons, moorings and current lines — and almost always on the up-current side of structure where baitfish concentrate.

Once pressured or spooked, they become extremely difficult to hook. First instinct upon being hooked is to dive directly into reef and structure. Heavy drag pressure from the moment of hook-up is essential.

NSW Seasonal Calendar

Kingfish are present in NSW year-round but show distinct seasonal patterns driven by water temperature and the East Australian Current.

Best Times of Day

• Dawn (first 60 minutes of light) — consistently the most productive topwater window.
• Dusk (last 60 minutes of light) — second best topwater window.
• Changing tides — the first push of a run-in tide concentrates baitfish at any time of day.
• Midday — fish generally sound deeper; target with jigs and sub-surface presentations.

Where to Find Them — NSW Locations

Kingfish range the entire NSW coastline but concentrate in predictable areas. They are almost always associated with current, structure, and bait.

Sydney Harbour

One of the best urban kingfish fisheries in the world following the removal of commercial traps in the mid-1990s. Large numbers of fish — including genuine metre-plus specimens — are caught year-round.

Offshore Sydney Reefs

Central Coast

Port Stephens, Jervis Bay & South Coast

Port Stephens offers exceptional kingfish fishing around offshore islands — Broughton Island is the headline destination. Jervis Bay's Point Perpendicular and "The Tubes" are among the most revered land-based game fishing venues in Australia. The South Coast's Montague Island (one hour northeast of Bermagui by boat) is a genuine kingfish mecca — the north edge is particularly productive when currents run. Green Cape's Pulpit Rock is one of NSW's most famous land-based game fishing ledges.

Port Stephens

Port Stephens sits at the northern end of the Hunter region and offers a unique combination of protected harbour fishing and fast access to offshore islands. The area fishes best October–March, with Broughton Island the undisputed centrepiece for serious kingfish work. The Cabbage Tree Island group and Fingal Island provide strong back-up options and are far less pressured.

Jervis Bay

Jervis Bay is a geographical anomaly — a deep, clear-water bay almost entirely enclosed by national park, producing some of the clearest inshore water on the east coast. This exceptional visibility makes it both a challenging and highly rewarding location: the fish are pressured and wary, but when they're active the sessions are unforgettable. Point Perpendicular and "The Tubes" are iconic Australian land-based game fishing venues with legitimate international reputations.

South Coast

The NSW South Coast from Ulladulla to the Victorian border offers some of the most spectacular and least pressured kingfish fishing in the state. Cooler water drives exceptional fish condition, and the proximity of the continental shelf to the coast means offshore species are accessible in shorter runs than further north. Montague Island is the centrepiece — a genuine world-class kingfish destination during autumn and winter.

NSW, New Zealand & Japanese Hiramasa — Size Context

Seriola lalandi is the same species whether it's called kingfish, haku, kingi, or hiramasa — but where it lives dramatically changes how big it gets, and that directly determines how you fish for it. Understanding this context explains why lure sizes, tackle weights, and approach philosophies differ across NSW, New Zealand, and Japan.

Why NSW Fish Are Smaller — and What That Means for Lure Selection

NSW kingfish are the same genetic species as NZ haku and Japanese hiramasa. The size difference is primarily driven by food availability, water temperature range, and fishing pressure — not genetics. NSW fish reach exceptional sizes too (the Solitary Islands, Lord Howe Island, and offshore reef produce genuine 25–35kg fish), but the general school population runs smaller than NZ.

The practical implication is lure sizing. A 5–10kg NSW rat king will hit a 150–180mm lure readily. A 20–35kg NZ kingi or 20kg Japanese hiramasa responds better to 200–240mm presentations — a larger meal profile that filters out smaller fish and better triggers the predatory instinct of big ones. When you see Japanese anglers using 220mm as their starting size, they're calibrating for a different average fish than a typical NSW session. For NSW anglers specifically targeting large fish (15kg+), sizing up to 200–220mm is worth doing — the lure selection philosophy from Japan applies directly to trophy NSW hunting.

The Japanese Hiramasa Game

The entire modern topwater kingfish tradition — the diving pencil, the long sweep retrieve, the Japanese lures that now dominate tackle bags across NSW and NZ — was invented in Japan. Understanding where it came from and how Japanese experts think about hiramasa changes how you fish.

The Origin Story

Hiramasa casting with diving pencils as a dedicated technique is surprisingly recent. Until the mid-2000s, vertical jigging was the dominant method for targeting hiramasa in Japan. The casting game was essentially nonexistent. The change happened in two places simultaneously: the Genkainada Sea off the northern coast of Kyushu (around Tsushima Island, Nagasaki Prefecture) in the west, and Sotobo in Chiba Prefecture in the east — both roughly around 2006–2008.

The pivotal moment was the 2010 release of a DVD called "A Complete Guide to Casting for Kingfish", produced by SALTWORLD magazine at Sunrise charter boat, Karatsu, Saga Prefecture. Captain Seiichiro Tashiro — widely credited as one of the founding figures of the Genkai casting game — skippered the sessions. The DVD featured anglers from CBONE, MC Works, and Melon Shop Kobo, and introduced the technique to anglers across Japan. It sparked a national movement. The Genkainada became the "sacred land" of Japanese hiramasa casting.

From Japan, the technique moved to New Zealand — largely carried by visiting Japanese anglers who shared knowledge with local guides, most prominently in the Bay of Plenty and Tauranga region. This cross-pollination accelerated through the 2010s and is the direct reason Japanese lures dominate premium topwater tackle globally today.

The Japanese Approach — How It Differs From Australian Practice

The Tide-Trigger Principle — Japan's Most Important Insight

The single most actionable thing Japanese hiramasa masters know that many Australian anglers don't apply with sufficient precision: large hiramasa feed specifically at tide transitions. Expert Kei Hiramatsu documents this with remarkable specificity across 29 years of Tsushima data — his three personal fish over 20kg were all caught either "just before the tide stopped" or "at the very beginning of the tide flowing." When the tide is dead — fish are dormant. When it starts moving, bait spreads against the reef structure, hiramasa become active, and the window opens.

What this means practically: Japanese anglers don't distribute effort evenly across a session. They conserve energy during slack tide, probe efficiently, and then fish with maximum focus and concentration during the 30–45 minutes around each tide change. This is fundamentally different from casting continuously for eight hours hoping to intercept a fish. Understanding tide transitions as the primary variable — not time of day, not weather, not bait presence — is the Japanese mental framework.

Line Action vs Point Action — The Japanese Retrieve Framework

Japanese topwater and jigging experts use a two-mode mental framework that doesn't have a direct equivalent in Australian fishing culture:

Line action (line luring) — A wide, sweeping probe covering broad water column layers. Think of it as spatial search mode. When the fish finder shows bait scattered across a broad zone, or when no specific fish have been located, line action covers ground efficiently. In topwater terms, this means covering water systematically in multiple directions, keeping track of which angles haven't been fished. In jigging, it means using a one-pitch action that pulls the jig through the widest possible layer of interest.

Point action (point luring) — Precise, controlled movements in a tight zone where you've identified specific fish or structure. This is concentration mode. When the sounder marks fish on a specific reef feature, or when a follow has been observed at a particular spot, point action means working the lure intensely through that zone with fine movement control. In topwater, this is the time to vary action depth, sweep length, and pause timing with precision rather than covering distance.

The key skill is knowing when to shift between them. Experienced Japanese anglers read the sounder, watch the bird pile, and observe the tide to decide which mode applies at any given moment.

Working with Wave Rhythm

In chop and swell, Kei Hiramatsu uses a specific technique: time each rod sweep to dive the lure through the wave trough rather than fighting the surface. The approach is to watch the approaching wave height, pull the lure's head under just as the wave crest passes, then pause as the next wave builds. This keeps the lure in the water working rather than catching air on the face of waves. In his words: "Produce a fine pulling bubble while letting the rod tip plunge into the wave crest head. Pull and pause when the next wave height approaches the plug."

The "Let It Dive" Response to Following Fish

When hiramasa follow a surface lure but refuse to commit, the instinctive Australian response is to burn and kill (speed up then stop) or change colour. Japanese practice adds a third option: let the lure dive deeper. By adjusting the sweep so the lure runs 30–50cm below the surface rather than creating maximum surface disturbance, the presentation changes character. A following fish that has assessed the surface commotion as suspicious may commit to the same lure once it drops below the interface. Suenaga's documented 13kg fish in the Genkai Sea article came specifically by "using the lure in a slightly diving manner" on a day when standard surface presentations failed repeatedly.

Japanese Bait Size Matching — Getting the Info

Japanese anglers treat the captain as the primary data source for bait size. Before each drift, the captain announces depth and sounder findings. This directly drives lure selection: "The captain mentioned that the bait size was around 20cm — we switched to the Bettyu Hiramasa 190F." Matching lure length to observed bait length is practiced with the same precision that an inshore angler matches fly size to a hatch. Ask your boat captain what bait they're marking on the sounder — not just where the fish are, but what size the bait is showing.

Japanese Jigging — The Kei Hiramatsu Method

While this guide focuses primarily on topwater, the Japanese approach to jigging for hiramasa deserves its own treatment. Kei Hiramatsu — 29 years targeting hiramasa, author of "Kei Hiramatsu's Hiramasa World", and representative of K-FLAT Co. Japan — has systematised hiramasa jigging to a degree that translates directly to NSW deep-water kingfish sessions. His framework applies wherever big Seriola lalandi hold over deep reef structure.

The Two Fundamental Jig Actions

Every decision Hiramatsu makes starts with choosing between two jig action modes, which he calls "line action" and "point action" — the same framework that governs his topwater approach.

In jigging, line action uses a one-pitch action (one lift per reel crank) that moves the jig through a wide vertical range while searching. The jig covers a broad column efficiently, appealing to any fish in the zone. Used when sounder marks show bait scattered across a wide layer, or when the first drift hasn't produced and you're mapping the field. The jig is a search tool as much as a catching tool.

Point action means micro-movements — a fine "chewing" of the jig, hovering it, and precise control within a tight zone. Used when you've located specific fish marks on the sounder, or when fish are responding to the jig but not committing. One angler in the Hachijojima trip documented: "She was able to get the hit by chewing the lure finely" — a specific fine-movement technique that contrasts with the broad-sweep power jigging more common in Australian practice.

Tide — The Master Variable

Hiramatsu states this simply: when the tide moves, fish eat. When the tide is dead, fish don't. At fish reefs in winter, the mechanism is clear: tide current causes baitfish to spread out against the reef structure. Fish that were holding tightly together in a defensive school become spread, accessible, and feeding. The moment the current starts moving, behaviour changes. His advice: position the boat just below the fish reef, let the drift carry the boat across the top of the reef as the tide rises — the "dotella method." Time the aggressive jigging to coincide with the tide starting or stopping, not simply when you feel like casting.

Seasonal Bait Knowledge Changes Jig Selection

A Hiramatsu insight specific to the Japanese fishery but directly applicable to NSW: the prey a hiramasa is feeding on changes its mouth morphology and therefore its aggression profile.

In summer at shallow rapids and inshore reefs, hiramasa feed on crustaceans. Their mouths develop a jagged, well-developed bite suitable for crustacean prey. These fish are aggressive biters that respond well to fast, erratic jig action — they're practised at catching nimble prey.

In winter/deeper conditions, fish holding at fish reefs feed on sardines and squid eggs. Their mouths are less jagged, reflecting a softer prey diet. These fish respond better to slower, more subtle jig movements — the fine point action. Aggressive one-pitch jigging on winter deep-reef fish may produce fewer bites than a hovering, subtle presentation.

For NSW: summer inshore kings around baitfish schools → fast aggressive jigging. Deep-water winter kings at offshore structure → try slowing down and introducing hover pauses.

Jig Weight Selection — Reading the Water

Japanese jigging starts with a calibration jig to read the field, not a direct fishing jig. Hiramatsu typically starts with his KEI Jig Sharp (a fast-dropping, streamlined jig) to assess current speed and depth without stress — the jig drops quickly to give clean feedback on what the water is doing before selecting the main working jig weight. He then adjusts for the actual fishing phase.

The "Hover" Technique

One Hiramatsu signature move for when fish are marking on the sounder but not biting: the hover. Rather than continually cycling one-pitch jerk-and-drop, he lets the jig hang almost motionless in the zone — a "Gummy fat" style wide-profile jig that holds depth easily — then makes minimal movement before a brief flutter drop. The concept is that fish on the sounder have noted the jig but haven't committed. The hover gives them extended time to make a decision with a stationary target that doesn't require chasing. The sudden flutter-drop then triggers the reflex strike. This is the opposite of conventional power jigging.

Lure Colour Science & Conditions Guide

Colour selection for kingfish is genuinely important. Understanding how light behaves underwater allows informed decisions rather than guesswork.

The Science

Water absorbs light wavelengths predictably. Red is absorbed within 10 metres, orange by 40 metres, yellow by 100 metres. Blue and green penetrate deepest. Silver and chrome only work by reflecting direct sunlight — in overcast conditions, chrome becomes nearly invisible. Fluorescent colours emit light after absorbing UV wavelengths, which penetrate cloud cover — making fluorescent pink and chartreuse visible in overcast conditions where chrome disappears.

Colour by Condition — Master Reference

Green Water — Special Rules

Sydney Harbour and most NSW inshore water is green, not blue. Chrome/silver becomes largely invisible — reflects green-grey water back. Chartreuse dominates. Gold catches warm ambient light even in murky conditions. White creates maximum contrast from below. Pink/fluoro activates on UV even in overcast green water.

Saury & Baitfish Colour Intelligence

Pacific saury is one of the most important kingfish baitfish on the NSW coast — particularly April–July when autumn schools push inshore. Understanding its exact colour profile directly informs lure selection during the most productive months of the year.

Live Saury — Colour Zone Anatomy

Saury are slim, fast-moving pelagics (20–30cm) with a highly distinctive colouration that sets them apart from pilchards and mackerel. The defining characteristic is the back: a deep teal-blue that appears almost black at speed, combined with blazingly bright iridescent silver flanks.

The CSP S180S (180mm / 100g sinking stickbait) comes in over 30 colours. During the saury run, the following ranking applies — from best baitfish match to situational alternatives.

Lure Selection — Types & Sizes

Kingfish respond to a wide range of lures. Understanding which type to deploy in which situation — and how target fish size in your specific location should influence lure length — is the key to consistent results. See the NSW, NZ & Japanese size context section for a full breakdown of how lure size should scale to target fish size.

Surface Poppers

Cup-faced poppers create a loud blooping sound and large splash that calls fish up from depth. Best in rough or low-light conditions. Not always as effective at converting follows into strikes as stickbaits, but excellent at locating and raising fish.

• Best conditions: Rough water, low light, choppy surface, calling fish from depth
• Retrieve: Sweep rod downward 45–50°, pause, repeat. Vary rhythm and intensity.
• Key sizes: 105mm (harbour/inshore), 135–160mm (all-round boat), 160–200mm (rocks/offshore)

Floating Stickbaits

The most consistent performer for topwater kingfish. Their realistic profile and erratic S-action convinces following fish to commit more reliably than a popper. Best in calm to moderate conditions.

• Best conditions: Calm/light chop, clear water, pressured fish, visible fish on surface
• Retrieve: Rhythmic sweeps creating a wide S-action. Never slow down when a fish is following. "Burn and kill" — wind hard then sudden stop — triggers reaction strikes.
• Key sizes: 150–190mm for offshore/rocks, 120–160mm for harbour/inshore

Sinking Stickbaits

Go-to when surface conditions are rough or fish are holding sub-surface. Sink to the depth fish are marking, then work with a rip-and-flutter action — the flutter on the pause is highly effective.

• Best conditions: Choppy/rough surface, fish holding mid-water, overcast, post-rain
• Key sizes: 130–160mm

Metal Lures / Slugs

High-speed metals (60–100g) are the foundation of land-based kingfish fishing from rock platforms. Cast long and crank back at maximum speed. Also effective from boats when fish are busting up and distance is needed.

Vertical Jigs

For kings holding deep over reef or structure. High-speed mechanical jigging (lift and wind) is the primary method. Match jig weight to depth and current. Slow-pitch jigging can work on fussy or pressured fish.

Soft Plastics

Large soft plastics (150–230mm paddle tails and stick shads) rigged on heavy jig heads are excellent for harbour and inshore kings. The Lunker City Sluggo 9" unweighted on a worm hook, worked with a walk-the-dog retrieve near the surface, is consistently one of the best harbour kingfish lures.
