9,275-acre Bynoe Harbour. East Australian saltwater fishing map showing only directly measured AusBathyTopo 2026 cells, source-qualified fishing spots, official regional fish evidence, seasonal forage context, access guidance and current-rule links. East trip-scale surveyed footprint within Bynoe Harbour. A mangrove-lined harbour southwest of Darwin with branching creeks, reefs and strong tidal channels. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 65 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Every species below gets its seasonal read from the same numbers driving the chart.
The drawn water covers 9,275 acres wrapped in 25.8 miles of bank. With a 1.9 development index there's bank structure worth casting at, in moderation. About 68% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 6.7 mi of water from one end to the other, 4.7 mi at the beam. Port Darwin - Central sits 5 mi east — the closest neighbouring chart.
Regional occurrence does not mean equal abundance, child-specific catch rate, retention permission or a promised catch. Live state, territory, Commonwealth, protected-area and local rules always control. The roster may combine exact-water monitoring with habitat-filtered official regional evidence; it does not imply that every species is equally abundant throughout the mapped section.

In spring, barramundi run shallow here, mostly 2 to 18 ft. Summer keeps them at 2 to 18 ft, and they winter in 11 to 35 ft. Sharp break is the standout, a drop-off at roughly 5 ft, rated good for fall barramundi. Time it for early morning and the evening.

Spring puts golden snapper in skinny water — 8 to 35 ft is the zone. Summer fish stay in 8 to 35 ft, and winter fish hold in 17 to 65 ft. Fall golden snapper concentrate at Sharp break, a good-rated drop-off around 5 ft. Warm-month bites cluster around early morning and the evening.

Early season black jewfish use the shallows, holding in 8 to 35 ft. Even in summer they hold at 8 to 35 ft; winter keeps them in 15 to 65 ft. Put Deepest basin first on the milk run — a deep basin near 53 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening.

In spring, king threadfin run shallow here, mostly 2 to 16 ft. Summer keeps them at 2 to 16 ft, and they winter in 10 to 35 ft. Shallow measured flat is the standout, a feeding flat at roughly 7 ft, rated prime for spring king threadfin. Time it for early morning and the evening.

Come spring, look for queenfish tight to the bank in 3 to 25 ft. Through summer count on 3 to 25 ft; the winter hold is 15 to 55 ft. If you only fish one area, make it Sharp break: a drop-off around 5 ft that scores prime in fall. Best bite is early morning and the evening.

In spring, giant trevally run shallow here, mostly 4 to 30 ft. Summer keeps them at 4 to 30 ft, and they winter in 15 to 65 ft. Shoreline point is the standout, a point at roughly 22 ft, rated prime for spring giant trevally. Time it for early morning and the evening.

No facility from the cited Northern Territory boat ramps source was spatially attached within 3 km of this directly measured map footprint during the 2026-09-08 audit. This is an evidence gap, not a claim that public access is absent. Check the official portal, live site signs, tides, ramp condition, vessel suitability, fees, parking, working-port restrictions and landowner permissions before travel: https://nt.gov.au/marine/for-all-harbour-and-boat-users/boat-ramps
Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for Northern Territory waters are set by the Northern Territory Government (current recreational-fishing rules) — and special regulations can apply to Bynoe Harbour - East specifically, so confirm the current rules before you fish. Check the Northern Territory's live possession and size limits and rules for specific areas before every trip. Seasonal barramundi controls, protected species, marine-park and Aboriginal land or sea-country permissions, method limits, vessel rules and local closures can apply. Remote-water access often needs separate landowner or permit approval. A mapped survey footprint, fishing spot or access lead never grants fishing, retention, entry, parking, camping or launching permission.

Bynoe Harbour - East is about 65 ft (20 m) deep at its deepest point. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled.
Official coastal monitoring from Northern Territory Department of Agriculture and Fisheries regional evidence informs the barramundi, golden snapper, black jewfish, king threadfin, queenfish, giant trevally, mangrove jack, narrow-barred spanish mackerel, coral trout roster for Bynoe Harbour - East. The mixed roster combines exact-water records where available with habitat-filtered regional evidence; not every species is documented at this exact water, and it is not a promise of equal abundance or a catch on a particular trip.
Deepest basin is the top-rated area: a deep basin in about 53 ft of water that rates prime for black jewfish in fall. Open the map above to see every rated spot for each species and season.
For barramundi, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Bynoe Harbour - East is regulated by the Northern Territory Government (current recreational-fishing rules). Check the official Northern Territory regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
