Moreton Bay / Brisbane Fishing — A Complete Guide
Moreton Bay + Brisbane fishing — snapper, threadfin salmon, mangrove jack, mackerel, whiting, bream. Brisbane River + bay system. Seasonal calendar + spots.
Moreton Bay is a vast 1500 km² bay system protecting Brisbane from the open Pacific. The combination of sandy banks, deep channels, mangrove systems, river mouths, and offshore islands (Moreton, North Stradbroke, South Stradbroke) supports extraordinary species variety — winter snapper to summer mackerel, year-round threadfin, mangrove jack, jewfish, queenfish, and the iconic Brisbane River bull sharks.
The geography
- Bay floor: Mostly 5–25 m sandy + reef bottom. Major channels (Rous, Pearl, Rainbow) cut through.
- Brisbane River: Major tidal river feeding the bay. Saltwater + brackish fishing 30 km upstream.
- Moreton + North Stradbroke Islands: Eastern bay edge; reef + offshore access via Moreton Bay's eastern boundary.
- Outer bay (eastern channels): Deeper channels approaching the open ocean — snapper + jewfish + mackerel grounds.
Top species + when they bite
- Snapper — Year-round on bay reefs, winter peak Apr–Sep. Coochiemudlo + Mud Island grounds.
- Threadfin Salmon (King Threadfin) — Brisbane River + bay flats. Vibes + plastics on tide changes.
- Mangrove Jack — Year-round in mangroves + bridges + structure. Plastics + hardbodies.
- Spanish Mackerel — Sep–Apr. Outer bay channels + bait balls.
- Mulloway — Brisbane River + bay channels. Year-round, dawn/dusk + tide changes.
- Whiting + Flathead — Sandy flats throughout the bay. Year-round.
- Bream — Mangroves + bridges + structure. Year-round; winter peak.
- Queenfish + Trevally — Bay's tropical edge — surface lures on bait balls.
Famous spots
- Mud Island — Iconic snapper ground 8 km offshore from Manly. Bait + soft plastics.
- Coochiemudlo Island — Bay snapper grounds + flats.
- Brisbane River (mouth + Gateway Bridge) — Threadfin + jewfish + mangrove jack. Tide-driven.
- Pearl Channel — Deep channel; jewfish + threadfin + bait.
- Rous Channel — Northern channel; snapper + bait.
- South Passage Bar — Offshore access via the bar; mackerel + tuna outside.
- Cape Moreton — Outer bay mouth; offshore work past here.
Conditions to watch
Sub-tropical, sheltered conditions. Bay water generally calm enough year-round; outer channels can stack sharp seas in opposing wind. Summer storms Dec–Mar bring afternoon squalls. Tide ranges large (2+ m) — tide planning is critical for the bay's vast flats + river systems. Brisbane River outflow after rain pushes muddy water through the lower bay; clean-water edges become the productive zones.
Reading BiteCast for Moreton Bay / Brisbane
- SST (sea-surface temperature) — Bay SST 18–28°C through year. Less critical than river/structure work; useful for outer-bay mackerel + tuna.
- Currents — Tide-driven currents in channels. Plan drift + anchoring around tide direction.
- Chlorophyll — River outflow + bay productivity edges. Threadfin + jewfish stack on clean-water edges after rain.

Frequently asked
Where do I catch snapper in Moreton Bay?
Mud Island (8 km offshore from Manly) is the iconic ground; Coochiemudlo, Peel Island, and the bay's outer reefs all produce. Winter (Apr–Sep) is peak. Soft plastics on light jigheads + fresh bait on snapper rigs.
Can I catch barramundi in Moreton Bay?
At the southern edge of barra range. They're caught occasionally in the Brisbane River + canal systems but in low numbers. Better targets in SE QLD are mangrove jack + threadfin salmon.
What's the deal with Brisbane River bull sharks?
Bull sharks are abundant in the Brisbane River + lower bay. Catch-and-release sport target on heavy gear; never swim in murky water. Also: mind your hooked fish on the way to the boat — sharks regularly take hooked jewfish + threadfin.
What are the best months for Brisbane River jewfish?
Year-round but autumn–winter (May–Aug) is peak as cooler water concentrates fish. Tide changes + dawn/dusk are key. Live bait + vibes + soft plastics on heavy jigheads.
