December marks the beginning of true summer fishing conditions along the Illawarra coast, and Wollongong comes alive as water temperatures climb and baitfish push tight to the coastline. The East Australian Current strengthens this time of year, bringing cleaner blue water closer to shore and triggering consistent pelagic movement along headlands, reefs, and current edges. Offshore, this is one of the most productive transition months, while inshore and rock fishing also improve as warmer water stabilizes near structure.
December fishing in Wollongong rewards anglers who pay attention to current direction, water colour, and bait presence. When the current pushes in clean and steady, pelagics move quickly and aggressively. When it stalls or pushes dirty water inshore, reef and bottom fishing become the reliable fallback. Flexibility is the key theme for December.
Offshore Fishing – Pelagics and Blue Water Action
Offshore fishing improves rapidly in December as warm water pushes south along the Illawarra shelf. Pelagic species become far more predictable, particularly when current lines sit within a few kilometres of shore.
- Yellowfin tuna moving along temperature breaks and bait schools
- Albacore tuna feeding higher in the water column
- Mahi mahi holding around floating debris and current lines
- Kingfish patrolling reef edges and pressure points
- Occasional marlin appearing on strong current days
Trolling remains the most effective method early in the month, especially along known routes east of Wollongong Harbour and toward deeper shelf water. As bait concentrations increase, live baiting becomes more productive, particularly for kingfish holding near pinnacles and drop-offs. When current speed increases, fish respond best to faster presentations and wider lure spreads.
Calm summer mornings are common in December, but afternoon sea breezes can build quickly. Most productive offshore trips start early, targeting pelagics at first light before conditions change.
Reef and Bottom Fishing
When offshore conditions are marginal or currents push dirty water inshore, Wollongong’s reef system provides reliable December fishing. The Illawarra coastline holds extensive reef and broken bottom that supports strong populations of table fish year-round.
- Snapper holding deeper reef edges
- Morwong and trevally around rough ground
- Flathead on sand and rubble transitions
- Leatherjackets in calmer conditions
- Pigfish and other reef species on deeper structure
Snapper fishing improves as water temperatures stabilize, particularly on dawn and dusk sessions. Fish tend to hold slightly deeper in December compared to peak winter months, responding best to lightly weighted baits and steady berley trails. Drift fishing becomes more effective than anchoring once current strength increases.
Kingfish – Wollongong’s Summer Target Species
December is a strong month for kingfish along the Wollongong coast, particularly around headlands, deeper reefs, and pressure points where current funnels bait. As water warms, kings become more aggressive and more willing to chase live baits and fast-moving lures.
- Live yellowtail or slimy mackerel near structure
- Slow trolling live baits along reef edges
- Vertical jigging on deeper pinnacles
- Casting stickbaits when fish are actively feeding
Kings are often mobile in December, moving with bait rather than holding tight to one location. Successful anglers focus on finding bait first, then working nearby structure thoroughly. When current is strong and clean, kingfish activity can be fast and explosive.
Inshore and Rock Fishing – Summer Access Improves
Inshore and rock fishing around Wollongong improves significantly in December as calmer conditions allow more consistent access to exposed platforms and headlands. Warm water brings baitfish closer to shore, drawing predators into reachable water.
- Australian salmon early and late in the day
- Bonito moving quickly along headlands
- Tailor feeding aggressively at dawn
- Drummer and bream on wash zones
- Trevally in deeper washes
Early mornings and late afternoons are the most productive windows. Lure casting from the rocks can be effective when bonito and salmon move through, while bait fishing remains reliable for drummer and bream. Safety remains critical, as summer swell can still rise unexpectedly.
Harbour and Estuary Fishing – Lake Illawarra and Local Systems
Lake Illawarra and nearby estuary systems fish steadily through December, particularly during tidal movement and early morning periods. Warmer water increases bait activity, which in turn improves predatory fish movement.
- Flathead holding drop-offs and channel edges
- Bream feeding around structure and weed beds
- Whiting active on sand flats during tides
- Trevally moving through deeper channels
Soft plastics and lightly weighted baits perform well, especially when water clarity is good. Flathead fishing remains consistent throughout December, making estuaries a strong option when offshore conditions are unfavourable.
December Fishing Outlook for Wollongong
December offers some of the most versatile fishing of the year in Wollongong. Offshore pelagics, reef species, kingfish, and inshore options are all viable depending on conditions. The most successful trips are those that adapt to current strength, water clarity, and wind patterns rather than locking into a single plan.
- Increasing pelagic activity offshore
- Reliable reef fishing when currents allow
- Strong kingfish presence on structure
- Improving inshore and estuary fishing
Wollongong in December rewards preparation, early starts, and flexibility. When conditions line up, the fishing can be fast, aggressive, and highly productive across multiple techniques.
