Murray River Cod
Murray cod are Australia's largest purely freshwater fish and the dominant predator of the Murray-Darling Basin.
Native to the river system that drains much of southeastern Australia, they draw anglers from across the country chasing fish that can push past a metre.
The fishery runs from small western-slope creeks to the main Murray channel, and the pursuit — casting big lures or flies into timber-choked bends — is as much about reading country as it is about tackle.
Scientific Name: Maccullochella peelii
Also known as Cod, Greenfish, Goodoo, Ponde, Pondi, Murray perch
- Yellowish-green to olive back with darker green mottling — a leopard-like pattern that makes them unmistakable among Australian freshwater fish.
- White to cream belly; large, bucket-like mouth built for engulfing prey whole rather than picking at it.
- Most fish caught run 50–80 cm; anything over a metre is a serious fish, and the largest on record reached 1.8 m and 113 kg.
- Distinguish from the closely related Trout Cod by the absence of a dark stripe running through the eye — Trout Cod carry that mark, Murray cod do not.
What to know
Habitat Distribution
- Native and endemic to the Murray-Darling Basin — the Murray, Murrumbidgee, Lachlan, Darling and their tributaries across NSW, Victoria, Queensland and South Australia.
- Favour slow to moderate flows with turbid water, submerged timber, undercut banks and overhanging vegetation across the river system's 2,500-plus kilometres.
- Also found in impoundments and lakes within the basin where they have been stocked or naturally occur; fish in larger waterways grow considerably bigger than those in small creeks.
- Rivers west of the Great Dividing Range that drain into the Murray-Darling catchment are the core habitat — remote sections with visible rock or timber structure hold the best fish.
Key Locations
- Murray River (NSW/Victoria border) — the main channel and its snaggy bends are the heartland of the fishery, with access points across both states.
- Murrumbidgee River (NSW) — a major tributary with strong cod populations, particularly in remote sections away from high-traffic access points.
- Darling River (NSW) — the northern arm of the basin holds good numbers of fish in its slower, turbid reaches.
- Lachlan River (NSW) — productive cod water through its mid and lower reaches, with timber structure throughout.
- Lake Mulwala and other Murray-Darling impoundments — flooded timber in storage lakes creates ideal habitat and some of the most accessible cod fishing in the system.
Specific Spots
- Submerged timber and fallen trees are the single most reliable holding structure — cod sit tight against logs, using them as cover and waiting for prey to pass.
- Undercut banks, especially on the outside of river bends where current has carved into the bank, shelter fish through the middle of the day.
- Rock bars and ledges in the main channel create current breaks where cod hold without expending energy, particularly in faster-flowing reaches.
- Deep holes and snaggy pools in remote sections away from heavy fishing pressure consistently produce larger fish — access via Google Earth research before you go.
Murray River Cod FAQ
Answers from onWater's species guide.
What are the best lures and bait for Murray River Cod?
Spinnerbaits are the most consistently productive lure across conditions and times of day, the vibration and flash work in turbid water and the weedless design handles snaggy timber without constant hang-ups.
What flies work for Murray River Cod?
Large deer-hair or foam surface poppers and divers (100–200 mm) draw surface strikes at low light, the commotion triggers the same response as a frog or small animal hitting the water.
When is the best time to fish for Murray River Cod?
Autumn (March–May), water cools after summer, fish feed actively to build condition and are more willing to move for lures; one of the most productive windows.
How do you catch Murray River Cod?
Most anglers work the banks of Murray-Darling rivers on foot or by boat, casting large lures or flies tight to timber, undercut banks and rock structure.
What do Murray River Cod eat?
Primarily other fish, including introduced species like perch, juvenile carp and goldfish, which is why large baitfish-profile lures and streamers draw strikes. Match the size of local baitfish when choosing lure length.
