88,430-acre Bynoe Harbour. Northeast 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. Northeast 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 122 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Here's the year, species by species, as the scoring engine sees it.
Drawn out, this is 88,423 acres of water rimmed by 57.9 miles of bank. A shoreline index of 1.4 says round and simple: fish relate to depth changes here, not shoreline features. 9% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 19.2 mi long by 13.5 mi wide at the broadest reach. For a second option, Port Darwin - Northwest lies 4 mi northwest.
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.

Early season barramundi use the shallows, holding in 2 to 18 ft. Even in summer they hold at 2 to 18 ft; winter keeps them in 11 to 35 ft. The chart's best answer is Sharp break — drop-off, 24 ft, good for fall. Best bite is early morning and the evening.

Spring golden snapper on Bynoe Harbour - Northeast hold shallow, usually 8 to 35 ft. Depth-wise the year is flat: 8 to 35 ft in summer, 21 to 80 ft once it turns cold. Put Sharp break first on the milk run — a drop-off near 24 ft that grades good for fall. The feeding windows run 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 - Northeast 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 - Northeast is about 122 ft (37 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.

Sharp break is the top-rated area: a drop-off in about 24 ft of water that rates prime for queenfish in fall. Every other rated spot, per species and season, is on the map above.
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.
