Australian Bonito

Australian Bonito

Australian bonito are a schooling, fast-water pelagic found along the east coast from southern Queensland down through NSW to Victoria and Tasmania.

Native to these waters, they're a genuine target for land-based rock anglers and boat fishers alike — fast enough to test light tackle, common enough to find regularly, and underrated on the plate when bled and iced immediately.

Scientific Name: Sarda australis

Also known as Bunny, Horse Mackerel, Little Bonito, Common Bonito, Skipjack, Striped Bonito

Physical Characteristics:
  • Torpedo-shaped body, dark blue-black on the back fading to silver-white on the belly, with nearly horizontal dark grey stripes along the sides — the near-horizontal stripe angle separates Australian bonito from Oriental and Leaping bonito.
  • Three keels on the caudal peduncle, two dorsal fins with a narrow gap between them, and a series of small finlets behind the second dorsal and anal fins — classic tuna-family architecture.
  • Large conical teeth in a single row — sharp enough to slice through braid leaders; wire or heavy fluorocarbon is worth considering.
  • Commonly caught at 40–50 cm and 1.5–2.3 kg; maximum recorded size is around 9.4 kg, though fish over 4 kg are uncommon inshore.

What to know

Habitat Distribution

  • Native to south-eastern Australia; the main recreational range runs from southern Queensland through NSW to Victoria and eastern Tasmania, with the bulk of fish encountered along the NSW coast.
  • An inshore pelagic — they work the zone from the surface down to around 30 m, hugging coastal reefs, headlands, rock ledges and the mouths of large estuaries rather than venturing far offshore.
  • Also found in bays and large estuaries, particularly when chasing baitfish schools pushed inshore by current or season.
  • Strongly associated with the Eastern Australian Current; their availability peaks in summer and autumn as warmer water pushes south along the NSW coast.

Key Locations

  • NSW south coast rock ledges around Batemans Bay — headlands that jut into shallow water are consistent producers from late summer onward.
  • Sydney's coastal reefs and headlands — bonito are a regular summer and autumn target for both boat and land-based anglers working the northern and southern beaches.
  • Southern Queensland to northern NSW — the northern end of the range sees fish earlier in the season as warm water arrives sooner.
  • Eastern Tasmania and the Victorian coast — the southern fringe of the range; fish appear when the Eastern Australian Current pushes warm water far enough south.

Specific Spots

  • Rocky headlands and ledges that jut into comparatively shallow water concentrate bonito — they use the structure to corner baitfish against the surface.
  • Look for working birds and white, foamy surface disturbance; bonito driving anchovies or garfish to the top is one of the clearest visual cues in east coast fishing.
  • Current edges and upwellings around reef points hold fish between feeding bursts — bonito rest in the calmer water adjacent to fast current, then push into the flow to feed.
  • In bays and estuaries, channel edges and bait schools near the mouth are the most productive zones, especially on an outgoing tide.

Australian Bonito FAQ

Answers from onWater's species guide.

What are the best lures and bait for Australian Bonito?

Metal slugs and chrome slices in 20–40 g are the go-to for land-based spinning, cast past the school and retrieve fast with an erratic, twitching action to mimic a fleeing anchovy.

What flies work for Australian Bonito?

Clouser Minnows (weighted flies that imitate small baitfish) in white, chartreuse, or silver are the most reliable pattern, the weighted eyes get the fly down fast and the jigging action on the strip triggers the same response as a fleeing anchovy.

When is the best time to fish for Australian Bonito?

Summer (December–February): peak season along the NSW south coast once water temperatures climb above 20°C; fish are most abundant and active. Autumn (March–May): fishing remains strong, particularly in Sydney and along the central NSW coast; schools can be large and predictable.

How do you catch Australian Bonito?

Most anglers target bonito by locating working birds and surface feeding activity, then casting metal slugs or small hard bodies into the school and retrieving fast.

What do Australian Bonito eat?

Primarily small schooling fish, anchovies and garfish make up the bulk of the diet along the NSW coast. Match these with slender metal slugs, small minnow-style hard bodies, or white/silver soft plastics in the 60–100 mm range. Also eat squid and small crustaceans.
