Where they live
Spotted Mackerel is a tropical Australian species. AU distribution: Queensland, Northern Territory, New South Wales. Typical depth 5–30 m. Wet vs dry season drives availability + behaviour.
Conditions to find them
Conditions to focus on:
SST
Filter for 21–27 °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
Hardbody minnows + suspending jerkbaits for barra + jacks. Vibes for threadfin + jewfish. Surface walkers + poppers for queenfish + GTs.
Baits
Top baits in AU: Pilchard, Live yakka. Live bait (mullet, prawn) is hard to beat for tropical species, particularly for big jewfish + barra in murky water.
Local knowledge
Schools in coastal waters in summer/autumn. Light tackle.
Seasonality by AU region
Tropical seasons are dry (May–Oct) vs wet (Nov–Apr). Spotted Mackerel availability changes dramatically across the cycle.
- Queensland: Pre-wet (Sep–Nov) + run-off (Mar–May) are lure peaks. Wet season (Dec–Feb) is dangerous + flooded.
- Northern Territory: Pre-wet (Sep–Nov) + run-off (Mar–May) are lure peaks. Wet season (Dec–Feb) is dangerous + flooded.
- New South Wales: Pre-wet (Sep–Nov) + run-off (Mar–May) are lure peaks. Wet season (Dec–Feb) is dangerous + flooded.
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 spotted mackerel is regulated under each state's recreational fishing rules:
- Queensland: verify on Queensland Fisheries recreational rules
- Northern Territory: verify on NT Fisheries recreational rules
- New South Wales: verify on NSW DPI Recreational Saltwater (or Freshwater) Fishing Rules
Marine park zoning may also apply — verify against current state rules. The above is descriptive reference, not legal advice.

What depth do spotted mackerel hold at?
Typical fishing depth 5–30 m. Use the BiteCast subsurface-temp layer at your fishing depth to confirm thermal structure.
What baits work for spotted mackerel?
Top AU baits: Pilchard, Live yakka. Live bait (mullet, prawn) is hard to beat for tropical species, particularly for big jewfish + barra in murky water.
