Every river mouth, harbour entrance and marina in Australia has a rock wall, and they are almost all publicly accessible. They combine deep water, structure and constant tidal flow — the three things that concentrate fish.
This guide explains how to read a wall, where the fish actually hold on it, and how to land a good fish from awkward rocks.
Reading a wall
The wall itself is only half the structure. The rock rubble that has slumped off its base creates caves and ledges below the waterline, and that is where bream, drummer and mulloway sit.
Look for the seam where fast channel water meets the slower water beside the wall. Predators face into the flow along that seam and intercept anything swept past.
Corners, kinks and the tip of the wall create eddies. An eddy is a food trap and is worth ten casts before you move on.
Working it with lures and bait
Cast up-current and let your lure or bait swing naturally past the rocks. A lure moving unnaturally against the current gets refused, especially by bream.
For mulloway, a soft vibe or 5" plastic hopped down the drop-off at the base of the wall on a run-out tide at night is the most consistent method in the country.
For bait, a running sinker rig with just enough lead to hold bottom, using fresh mullet, squid or live poddy mullet, covers everything from bream to jewfish.
Landing fish and staying safe
Plan your landing before you cast. Identify a low, safe rock where you can bring a fish up on a wave surge, or carry a long-handled net or a rope-tied lip grip.
Wet rocks below the tide line are covered in slime and cunjevoi — walk only on dry rock and wear cleated boots.
River-mouth walls are washed by ocean swell. Check the swell forecast before you plan to fish the outer half of any wall.
Key takeaways
- ▸Fish the rubble base and the current seam, not the top of the wall.
- ▸Cast up-current and swing your presentation past the structure.
- ▸Plan the landing spot before you hook a good fish.
