Bonito in Australia — The Complete Fishing Guide
How to find + catch bonito in Australian waters. SST 17–24°C. Typical depth 0–50 m. Lures, baits, seasonality, and BiteCast layer mapping.
Bonito is a regular target along Australian coastlines. Light-tackle target + great bait for marlin/mulloway. Schools chase bait inshore. This guide covers where they live, what triggers them to bite, and how to read conditions for them with BiteCast.

Where they live
Bonito hold in coastal waters: bays, headlands, beaches, near-shore reefs. AU distribution: New South Wales, Victoria, Tasmania, Queensland, Western Australia. Typical depth 0–50 m. Find them around structure that holds bait — washes, current breaks, drop-offs, weed lines.
Conditions to find them
Conditions to focus on:
SST
Filter for 17–24 °C surface water on the BiteCast map. Sharp temperature fronts (1–2 °C breaks over 5–10 km) within that range are where bait pins up — your best-confidence zones. See SST layer explainer.
Best techniques + tackle
Lures
Match the lure to the bite mode: surface lures at first/last light, hard bodies + plastics in the day, metals when fish are busting. Cast at structure + work upcurrent.
Baits
Top baits in AU: Cube pilchard, Live yakka. Fresh bait beats frozen by a wide margin. Pillies + squid are the standards.
Local knowledge
Light-tackle target + great bait for marlin/mulloway. Schools chase bait inshore.
Seasonality by AU region
Bonito are mostly available year-round but with seasonal pulses. Spring + autumn are usually the peak windows.
- New South Wales: Year-round with regional pulses; check local sources.
- Victoria: Year-round with regional pulses; check local sources.
- Tasmania: Year-round with regional pulses; check local sources.
- Queensland: Year-round with regional pulses; check local sources.
- Western Australia: Year-round with regional pulses; check local sources.
Common mistakes
- Not matching technique to conditions — generic approaches under-perform local-knowledge-driven ones.
- Ignoring weather forecasts — water + safety conditions matter more than your trip plan.
- Failing to verify current size + bag limits before keeping fish.
Compliance + regulations
Recreational size + bag limits vary by state and change regularly. Always verify current rules before keeping a fish. The bonito is regulated under each state's recreational fishing rules:
- New South Wales: verify on NSW DPI Recreational Saltwater (or Freshwater) Fishing Rules
- Victoria: verify on VFA (Victorian Fisheries Authority) recreational rules
- Tasmania: verify on Tasmanian Inland Fisheries Service / DPIPWE rules
- Queensland: verify on Queensland Fisheries recreational rules
- Western Australia: verify on WA Department of Primary Industries + Regional Development recreational rules
Marine park zoning may also apply — verify against current state rules. The above is descriptive reference, not legal advice.
