Ranked by how strongly flounder show at each mark. The chip on the right is today's live fish forecast.
Very reliable around estuary sand; peeler crab, rag or lug on running ledger; work the streamy gullies.
Common in the estuary channel; ragworm/madder or small crab baits on a running ledger, best on the flooding tide.
Reliable year-round; best on small crab, rag or maddie on a running ledger near slack water.
Reliable over mud/sand; ragworm, maddies or small crab. Best around slack/flood edges and channels.
Common in the bay; target low-water gutters and the first push of flood with lugworm, rag or small crab.
Common in the estuary influence; fish rag, maddie or small crab on a running ledger; good from late autumn through spring.
Takes rag/lug near any freshwater influence; short-range casts can score, especially on the flood.
Often close in, especially after rain/colour; worm baits and shorter casts can outfish long-range.
Classic harbour flatfish; ragworm or lug on a simple running leger; target edges of channels on the ebb/flood turn.
Can show close in, especially after rougher weather; lugworm and small strips of fish bait score.
Shows through cooler months; try lug/rag near any freshwater influence and on the flooding tide; shorter casts can work.
Often close in on smaller baits (rag/maddy); can show in cooler months and after a bit of colour in the water.
Can show near the estuary influence; lug/rag or small fish strip; try the first of the flood in coloured water.
Often inside/near harbour influence; ragworm or small fish baits, fish into slack water and around tide turns.
Occasional inshore on smaller tides; rag/lug baits and a slow retrieve can help on the sandier runs.
Scattered in mixed ground and the bay’s softer patches; rag/lug on light gear works on smaller tides.
