The single biggest factor in catching fish isn't the rod, the line, the lure or the bait — it's WHERE you fish. Predator fish hide where prey congregates and where ambush points exist. Knowing what to look for transforms a quiet day into a productive one.

Here's the practical guide to where fish actually live — rock walls, jetties, bridges, beaches, banks, and the structural features that hold fish.

Fish need three things constantly: food, oxygen, shelter. Find places that provide all three + you'll find fish.

• Structure — anything that breaks the smooth bottom or current flow. Rocks, weed beds, dropoffs, sunken trees, pylons. Provides shelter + ambush positions
• Edges — boundaries between two different habitats (deep/shallow, weed/sand, current/calm). Concentrate prey + predators
• Current breaks — places where moving water creates calm pockets behind objects. Predators rest there waiting for prey
• Tide changes — moving water concentrates feeding. The first and last hour of tide change are typically peak bite times
• Time of day — dawn + dusk are universally productive. Most predators feed in low-light conditions

Built to protect harbours + shipping channels — but also create some of the most fishable structure in coastal Australia.

• Why fish are there: rocks provide shelter; current breaks create ambush points; baitfish school in the calm water on the lee side
• Best spots on the wall: CORNERS where the wall changes angle, GAPS in the rocks, the END of the wall where current accelerates
• Tactics: cast LURE or BAIT to the base of the wall, retrieve along the structure, watch for follows. Use a swimming lure or float-rigged bait
• Common species: bream, drummer, luderick, tailor, salmon, mulloway (at night), even kingfish on bigger walls
• SAFETY: rock walls are slippery. Wear cleated rock-fishing boots, wear a PFD, never fish solo in big swell, never turn your back on the ocean

The classic Aussie family fishing destination. Easy access, deeper water reach, often productive.

• Why fish are there: pylons provide shelter + create eddies; weed grows on pylons + attracts prey; jetty lights at night attract baitfish + their predators
• Best spots: the END of the jetty (deepest water), GAPS between pylons, anywhere the jetty crosses a current line or channel
• Bait fishing: running sinker rig with prawn or pilchard. Cast straight out, let it sit. Bream, flathead, snapper, salmon
• Lure fishing: cast soft plastics tight to pylons; vary depth with jig head weight
• Night fishing: jewfish + flathead under the lights. Bring head torch + warm clothing

Often overlooked + very productive. Bridge pylons concentrate fish like jetty pylons but with the bonus of bridge shadows + current breaks.

• Why fish are there: shadow lines on sunny days create cover; pylons provide shelter; the bridge concentrates current
• Best spots: the SHADOW LINE on sunny days (predators wait in shade for prey moving through sun); pylon bases; the up-current side of pylons (where current breaks)
• Tactics: drift bait or lure THROUGH the shadow line, work pylons systematically, fish at peak tide changes
• Common species: bream, flathead, mangrove jacks (tropical), barra (north), bass (freshwater bridges)
• Always check local rules — many bridges have fishing restrictions for boat traffic safety

Surf beaches look uniform but actually have rich structure that fish use.

• Why fish are there: baitfish push into shallow surf water, predators follow. Currents in gutters concentrate baitfish
• Best spots:
  • Gutters — channels of deeper water between sandbars, identifiable as darker green/blue water
  • Holes — deeper depressions, often where waves break + then go calm
  • Headlands — where current accelerates around the rock
  • Creek mouths — fresh water + nutrients attract baitfish
• Tactics: long surf rod, gang hooks with whole pilchard or 3-4kg test for big fish. Cast into gutters not onto sandbars
• Common species: tailor, Australian salmon, mulloway (jewfish), flathead, bream, snapper

• Why fish are there: bank structure (overhanging trees, fallen logs, undercut banks) provides shelter + ambush positions
• Best spots: SNAGS (fallen trees in the water), UNDERCUT BANKS (where the bank curves under at the waterline), WEED BEDS, OYSTER LEASES (in estuaries — great for bream)
• Tactics: work LURES tight to the structure. Soft plastics worked along the bottom near snags. Lift + drop technique
• Common species: bream, flathead, bass, mangrove jacks, Murray cod (freshwater snags), barra (tropical river bends)

From a boat you can find structure invisible from shore. Sounder + GPS unlock entirely new productive water.

• Reefs + bommies — show as harder bottom on the sounder. Snapper, kingfish, samson
• Drop-offs — depth changes from 5m to 20m+. Predators sit on the edge waiting for baitfish
• Sunken wrecks + structure — local knowledge or marine charts identify these
• Bait schools on the sounder — predators are nearby. Fish DOWN to where the schools are
• Open water + offshore — pelagics like tuna, kingfish, marlin follow temperature breaks + bait schools

Where you fish matters more than what you fish with. Find structure, find edges, fish at the right time of tide + day, and you'll catch fish on basic gear. Fish open water with no structure with the world's best gear and you'll catch nothing.

Spend more time at fewer spots. Learn each spot deeply — what species, what tide, what time, what technique. The patient angler who knows their water always outfishes the visitor with all the gear.
