The Colosseum or Colo as the locals call it, is a large estuary system only 30mins drive south of  Gladstone.The Colosseum is a declared fish habitat protection area, which means you can still fish and crab like any other fishing spot, more information here. Apart from the mouth and first few kilometers of the main channels, the creek system is relatively shallow. There are no real concrete boat ramps to access the Colosseum Creek for fishing except 2 hard sand/gravel ramps accessed via bush tracks. These boat ramps are suitable for small to medium sized boats and from mid-high tide. The boat ramp at foreshores is accessible on all tides, however Wild Cattle Creek becomes quite shallow and treacherous.

Colosseum creek fishing spots are really only for fishermen with boats or a kayak. Crocodile sightings are extremely rare however not unheard of. Anglers wanting to fish the Colosseum and Wild Cattle Creek can expect Bream, Whiting, Flathead, Cod, Grunter, Trevally, Crabs and for the more dedicated angler Mangrove Jack and Barramundi.

The expansive shallow flats generally have gravelly bottoms, with shellfish, mussels and small patches of seagrass, there spots are great on an incoming tide as the Bream, Whiting and Flathead all begin to forage. Trevally also lurk on the flats and can often be sight casted, most fish are around the 40-50cm mark.

The tributaries have rock bars, deep holes and further upstream snag lined banks. The rock bars mostly have cod and the odd mangrove jack. Deep holes can sometimes hold Jew and Grunter. Further upstream the snags have Mangrove Jacks, Bream and Cod, these are best fished on an incoming tide.

Out from the river mouth, the south west beach and sand flats can provide good flats fishing in Winter. Blue Salmon and Golden Trevally are often lurking these flats particular in the corner close to the first headland.

Further offshore there is a fishing spot named Seal Rocks. This is a large rocky outcrop only 5kms from the Colosseum and roughly 8km from the Foreshores boat ramp. Seal Rocks has a fair amount of fishing pressure, however there are a lot of fish around, such as Tuskfish, Coral Trout, School Mackerel and a large population of Mother-in-Law! South from seal rocks a long sand bar runs back towards the mainland, here Giant Herring have been caught on fly. Seal rocks is a great spot for Spear Fishing, especially in the winter months as the water clears up and during a neap tide.

There are many opportunities at seal rocks, some massive Tuskfish lurk around here for anglers that pay attention, top tip: crab is the best bait.

The estuary system is also a popular spot amongst locals for mud crabs. Adventurers and keen fishos can camp on the eastern side of the river mouth and access their boat at all times due to the steep banks. The camping spot is well protected from SE trade winds and SE swells.
