What Are the Noosa Everglades?
The Noosa Everglades is one connected Everglades-type system stretching more than 65km across the 85,000 hectare Noosa River catchment: from the upper Noosa River, through the lakes of Como, Cooloola, Cootharaba, Cooroibah, Doonella and Weyba, to Laguna Bay and the Coral Sea. Lake Weyba is its southern end.
It is often described as one of only two Everglades systems in the world, the other being Florida's.
The Noosa Everglades System
A landscape of rare ecological diversity, from nationally important wetlands to calm estuarine shallows and ancient river corridors.
60+ Regional Ecosystems
Intertwined Ecosystems Living as One
Rainforest, wallum wetlands, floodplains and river forests flowing together as one landscape.
The catchment supports 61 regional ecosystems, 1,340 plant species and 217 bird species, including half of all known migratory shorebirds (Noosa Integrated Catchment Association).
Nationally Important Wetlands
Two Directory-Listed Wetlands
Noosa River Wetlands and Lake Weyba are both listed in the Directory of Important Wetlands in Australia, and the river mouth shelters migratory shorebirds of the East Asian-Australasian Flyway.
1/3 National Park
National Park & Conservation Estate
Almost a third of the catchment lies in the Cooloola section of Great Sandy National Park alone, with Tewantin and Noosa national parks protecting more.
Globally Rare Hydrology
An Everglades-Type System
A whole catchment shaped by slow-moving, interconnected water, falling only about 80 metres from its headwaters to the sea.

Migratory Birds & Marine Nurseries
Globally Connected Wildlife
From sea eagles and jabirus to stingray nurseries in Lake Weyba, the system supports species that link continents.
Where Every Part Shapes the Whole
This ancient waterway is not a single place, but an interconnected system, each part shaped by the flow of the whole.
Catchment-Scale Hydrology
Water Moves Across a Whole Landscape
An Everglades system is shaped by slow, interconnected water flow across wetlands, lakes and floodplains, not confined to a single lake or river reach.
Connected Wetlands
Multiple Ecosystems Functioning as One
Swamps, marshes, forests, estuaries and lakes operate together as a living network.
Slow, Filtered Water Movement
Sheet Flow Over Surge Flow
Water spreads, filters and settles through vegetation and porous soils, creating distinctive chemistry and ecological stability.
A Salinity Continuum
Freshwater to Marine, Seamlessly Connected
An Everglades system transitions gradually from freshwater wetlands to brackish estuary to coastal marine waters, without hard ecological breaks. In Noosa, tidal water typically reaches as far upstream as Harry's Hut.
Lake-to-Sea Connectivity
Nothing Exists in Isolation
Uplands, wetlands, rivers and estuaries remain physically and biologically connected, forming one integrated landscape.
Key Regions of The Noosa Everglades System
An Everglades is a whole landscape connected by water.
Across the Noosa River catchment, 61 regional ecosystems merge as one, creating a remarkable, fully connected Everglades-type system.
The Iconic River of Mirrors
Narrow, glassy and deeply still, the Upper Noosa River is the purest expression of the Everglades character. Tannin-rich, dune-filtered waters mirror ancient tea-tree forests in near-perfect symmetry. Paddle quietly and the outside world dissolves into birdsong, shifting light and silence.
This is the landscape most commonly associated with the Noosa Everglades, yet it represents just one part of a much larger, interconnected system.
The Open Water Heart
Vast, wind-brushed and luminous, Lake Cootharaba gathers the upper catchment into one expansive horizon.
Shallow, sunlit waters support waterbirds and aquatic life, while open skies and distant sand dunes create a sense of scale rarely found so close to the coast.
Southern Gateway to the Noosa Everglades System
Quietly secluded and expansive, yet easily accessible. Lake Weyba is framed by paperbark forests and wallum heath. Its calm shallows support abundant birdlife and wetlands of national significance. Here freshwater and tidal influence gently overlap, and stingrays glide through protected breeding areas. Lake Weyba drains into the lower Noosa River, and the Queensland Government maps it as one of the Noosa catchment's own subcatchments.
Harry's Hut
Gateway to the Upper Wilderness
Nestled within Cooloola’s forested corridor, Harry’s Hut marks the transition into the most intimate reaches of the system. From here, the river narrows, reflections deepen, and the sense of remoteness becomes unmistakable: a true immersion in wilderness.
Lake Cooroibah
Where Fresh Meets Salt
Wide, tidal and ever-changing, Lake Cooroibah is shaped by both river and sea. Mangroves fringe its edges, pelicans glide overhead, and the rhythm of the tides connects the catchment to the ocean beyond.
"The Noosa Everglades system is an uninterrupted journey of water from headwaters to sea, shaped by natural gradients and connection, not arbitrary boundaries"
Lake Como
The Floodplain Spillway Lake
Quiet, shallow and changeable, Lake Como is where the river can breathe during big water. In wetter periods, high flows spill into the lake and then continue on toward Lake Cootharaba, spreading energy across the landscape rather than forcing it through one point.
Lake Doonella
Tidal Estuary Haven
Calm, sheltered and shaped by the rhythm of the tides, Lake Doonella sits within the lower estuarine reaches of the system. Mangrove-fringed shorelines and gently shifting salinity create rich habitat for fish and birdlife, while its protected waters offer a tranquil counterpoint to the open bay beyond. Here, river and ocean quietly converge.
Lake Cooloola
The Freshwater Window
A rare freshwater lake fed through sand and alluvium, Lake Cooloola feels like a hidden clarity within the wider system. What makes it special is its proximity to estuarine waters, a vivid reminder that this Everglades-type landscape is defined by transitions, not hard boundaries.
Laguna Bay / Lower Noosa Estuary
Ocean Connection
Clear blue water and sweeping headlands mark the final chapter of the catchment’s journey. Everything upstream eventually arrives here, where freshwater merges with the Coral Sea in a rare and uninterrupted lake-to-sea continuum.
