Mary River, Queensland

Queensland’s Mary River marks the barramundi’s southern limit on the East Coast, with regular catches in the river and occasional fish from the labyrinth of channels, flats and tidal creeks that make up the Great Sandy Strait into which the river flows.

The 290km river begins at Booroobin in the Sunshine Coast hinterland. It flows through the towns of Kenilworth, Gympie, Tiaro and Maryborough before emptying into the sea at River Head on the Great Sandy Strait, between the mainland and Fraser Island, 17km south of Hervey Bay township.

The river has 19 tributaries, including Tinana Creek, Munna Creek, Obi Obi Creek, Yabba Creek, Wide Bay Creek, Six Mile Creek, Deep Creek, and Susan River.

There are two impoundments on the river, being Gympie weir and the Mungar barrage, with several dams on tributaries, being Borumba Dam on Yabba Creek, Baroon Pocket Dam on Obi Obi Creek, Six Mile Creek Dam on Six Mile Creek, Cedar Pocket Dam on Deep Creek, weirs Talegalla and Teddington and a barrage on Tinana Creek.

Tidal fishing access for boaters is generally done from Beaver Rocks ramp 11km from the mouth, or River Head at the mouth, which is 35km downstream from Maryborough township.

Barramundi prefer the turbid water of the tidal river rather than the clearer waters of the adjoining Great Sandy Strait, but don’t expect the numbers of barramundi you may find in rivers further north.

There is however a real chance of catching a trophy saltwater barramundi or threadfin salmon in the Mary River.

Though barramundi are present, the main saltwater catch is whiting (summer, tin can and diver species), flathead, southern and pikey bream, tailor, blue and threadfin salmon, mangrove jacks , northern and southern jewfish, perch (which look like a small jewfish), cod, mud and blue swimmer crabs, and prawns.

There are many drying banks in the upper river and fishermen who explore on a falling tide may become landlocked in creeks or stuck on a sandbank, so explore first on a rising tide.

The river between Beaver Rocks and River Head consists of flats and channels that provide plenty of fishing opportunity.

Beaver Rocks, near the ramp at Beaver Rocks Road, is a popular area about 11km upstream of River Head, near the rivers Crab Islands. The rocks are at approx 25 29.718S 152 51.063E. There is a boat ramp 2km downstream from Beaver Rocks.

Beaver Rocks has deep water that fishes well, along with nearby flats around the Crab Islands.

A strong current flows through the channels, especially on the runout tide. Fish the turn or rising tide for best results.

flathead are found at the mouths of small creeks and gutters, as well as over tidal flats, especially near channels.

Whiting and flathead move over the flats on incoming tides.

Jewfish, bream and cod are found in the deep holes, and tailor chase bait in the deeper areas of the estuary.

On big tides, try fishing for barramundi with lures or livebait at the mouths of the larger draining mud gutters.

Barramundi should be targeted in warm weather. Being large fish with a distinctive shape, barramundi can be located with diligent use of a good sonar unit.

Prawns are best from around January.

Further upstream, a rocky area to watch for is Leslie Rocks at approx 25 30.596S 152 45.928E. More foul ground exists upstream towards Dundathu at approx 25 28.814S 152 44.677E. Look for warning and channel markers.

Mary River freshwater fishing

Good freshwater fishing can be had on the Mary River freshwater right up to around Gympie.

Bass are stocked in the freshwater section of the Mary River, and sooty grunter and saratoga are also caught. Mary River cod are present.

Associated impoundments Lake Borumba and Baroon Pocket dams produce loads of bass. Borumba has bass, Mary River cod and saratoga.

Access points to the Mary River around Gympie include the kayak run from Kidd Bridge to Widgee Crossing. Normanby Bridge to Kidd Bridge or Fisherman’s Pocket is arguably best for fishing.

Also try the river near Six Mile Creek.

Freshwater barramundi can be caught at Lake Lenthall, on the headwaters of the Burrum River just to the north.

Note that the Mary River has saltwater crocodiles throughout.

Also note that Australia’s Northern Territory also has a Mary River, a famous barramundi fishing area.

Outside the Mary River mouth, the Great Sandy Strait includes a vast labyrinth of drying areas and channels with great fishing for whiting, flathead, bream and more.

The channel should be navigated on a rising tide with plenty of spare fuel. Channels are marked through the strait.

Reef fish are caught around most deep lumps and bumps, with the flats and associated channel edges providing mostly flathead, whiting and bream.

Nearby, the east side of Fraser Island is famous for its annual tailor run, with sharks and jewfish also taken.

Hervey Bay’s long Urangan Pier is a very popular landbased spot that produces big fish.

Occasional bonefish and permit occur in this area, with bonefish sometimes caught in deep water off Fraser island’s Rooney Point, but golden trevally and queenfish are the more likely catch for those chasing sportfish in the shallows.

Slatey bream (blackall), pink snapper, coral trout, cod and sweetlip are caught on local reefs.
