12,973-acre Byron Bay. North 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. North trip-scale surveyed footprint within Byron Bay. An exposed subtropical bight of reefs, headlands, beach gutters and current-facing nearshore contours. The displayed footprint is not a legal boundary or a claim of complete named-water coverage. The water tops out around 222 ft. The depth chart comes from Geoscience Australia / AusSeabed bathymetric survey data, so the contours are survey-derived rather than computer-modeled. What the data behind the map says about each species, season by season:
Byron Bay - North maps at 12,972 acres behind 23.3 miles of shoreline. With a 1.5 development index there's bank structure worth casting at, in moderation. 14% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Figure 9.2 mi of water from one end to the other, 3.1 mi at the beam. If the bite dies, Byron Bay - Northwest is 9 mi to the north.
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.

When the water first warms, australasian snapper slide up into 6 to 35 ft. By summer they slide out to 16 to 120 ft, and by winter most fish are in 21 to 120 ft. If you only fish one area, make it Sharp break: a drop-off around 92 ft that scores prime in summer. In summer the feeding windows fall in early morning and the evening.

When the water first warms, mulloway slide up into 5 to 30 ft. By summer they slide out to 14 to 100 ft, and by winter most fish are in 18 to 100 ft. If you only fish one area, make it Sharp break: a drop-off around 92 ft that scores good in summer. In summer the feeding windows fall in early morning and the evening.

Come spring, look for yellowtail kingfish tight to the bank in 8 to 45 ft. They move out to 20 to 130 ft in summer and finish the year down in 27 to 130 ft. If you only fish one area, make it Shoreline point: a point around 45 ft that scores prime in spring. Best bite is early morning and the evening.

When the water first warms, dusky flathead slide up into 2 to 15 ft. By summer they slide out to 7 to 35 ft, and by winter most fish are in 9 to 35 ft. If you only fish one area, make it Offshore hump: an offshore hump around 32 ft that scores good in summer. In summer the feeding windows fall in early morning and the evening.

Start shallow in spring: yellowfin bream sit in 2 to 16 ft that time of year. Summer pushes them deeper, 7 to 40 ft, and winter fish settle into 10 to 40 ft. The spot to know is Offshore hump, an offshore hump in about 32 ft of water that rates good for yellowfin bream in summer. Warm-month bites cluster around early morning and the evening.

No facility from the cited Transport for NSW Maritime 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.

Private land and private launches need the owner's permission — please ask first.
Season dates, license requirements, and size and bag limits for New South Wales waters are set by the NSW DPIRD (current saltwater recreational-fishing guide) — and special regulations can apply to Byron Bay - North specifically, so confirm the current rules before you fish. Check the live NSW saltwater guide before every trip, including current size and possession limits, seasonal and spatial closures, marine parks, protected species, permitted gear, intertidal collection rules and any local harbour or council directions. A directly measured depth cell, fishing-spot marker or access lead does not establish permission to fish, retain a catch, enter port land, park or launch, and rules can differ across one mapped operational section.

Byron Bay - North is about 222 ft (68 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 NSW Department of Primary Industries and Regional Development regional evidence informs the australasian snapper, mulloway, yellowtail kingfish, dusky flathead, yellowfin bream, australian salmon, tailor, silver trevally, luderick roster for Byron Bay - North. 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.
Sharp break is the top-rated area: a drop-off in about 92 ft of water that rates prime for australasian snapper in summer. Every other rated spot, per species and season, is on the map above.
For australasian snapper, 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 Byron Bay - North is regulated by the NSW DPIRD (current saltwater recreational-fishing guide). Check the official New South Wales regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
