Overview
The Spotted Mackerel is one of the most popular pelagic species along Australia's east coast. Incredibly fast and aggressive, it attacks any fast-moving lure. Arrives in large schools during autumn and winter, creating a fishing frenzy.

How to really catch it
The Australian spotted mackerel is a fast, streamlined, high-strung pelagic fish, built to chase schools and strike decisively. When coastal water comes alive along reefs and beaches, seeing it switch into feeding mode means a clean, fast fishery of hard hits and long surface runs.
🐟 Good to know
Its eggs are pelagic, small and transparent, and the larvae also remain pelagic in their early stages, with rapid fin development that helps them swim in open water. That fits a species that lives in schools and uses open, dynamic coastal habitats.
🌊 Where & when
It is found mainly along Australia’s eastern coast, from Queensland to New South Wales, in 5 to 50 meters of coastal and pelagic water near reefs, sandy areas, bays, and current lines. It is highly active in fall and winter and through the long peak from March to November, while from June to August it makes migrations linked in part to spawning.
🎣 How to really catch it
The most direct way to target it is fast spinning with metal lures or artificials worked on the surface and mid-water, keeping a 7-8 foot medium-heavy rod ready for quick casts at moving schools. Trolling and live baits also work well near reefs and current, while 20-30 lb line and a steel or fluorocarbon leader help deal with sharp teeth, long runs, and jumps.
💡 The detail that makes the difference
The practical edge is not to waste time on the bottom: this mackerel feeds as a pelagic hunter, chasing small fish, squid, and crustaceans in open water. If you see activity near the surface or mid-column, run the lure fast across the edge of the school, not through the dead water after it has passed.
Catch & handling tips
- Fight
- Strong fighter, known for long runs and jumps out of the water.
- Handling
- Use gloves to avoid cuts from sharp teeth.
- Release
- Avoid touching the gills, release quickly into the water.
