Imagine a desert blossoming into life. That's the reality in a remote corner of New South Wales, where floodwaters from Queensland have transformed the landscape into a thriving oasis.
Last year's floods in southwest Queensland sent water surging down the Bulloo River, through the Bulloo Overflow, and into the Narriearra Caryapundy Swamp. This isn't just any wetland; it's an ephemeral one, meaning it only fills with water every 10 to 20 years.
Getting there is an adventure in itself: a 17-hour drive from Sydney to the Corner Country, close to the Queensland border and the iconic dog fence. River ecologist Professor Richard Kingsford describes it as "an incredibly healthy system," highlighting its natural rhythms, which have been occurring for thousands of years. He believes it's one of the most remarkable wetlands in the country.
This area, a 70,000-hectare wetland, received Ramsar listing in 2021 and is part of the larger Bulloo Overflow. Professor Kingsford noted that the 2024 floods in Thargomindah were more significant than those in the 1950s and 1970s, potentially causing the wetland to experience its largest infill ever.
"When you survey it from a light aircraft, and it takes hours to go back and forth, you just realize what an amazing natural phenomenon this is," he said.
A Birdwatcher's Paradise
Around five years ago, the New South Wales government purchased the 150,000-hectare Narriearra Station, allowing scientists, rangers, and local Indigenous people to appreciate its ecological and cultural significance.
In October 2025, a survey estimated that between 200,000 to 300,000 birds were in the area. The survey involved flying just 50 meters above the water, with researchers using tape recorders to identify and estimate the bird populations.
They spotted approximately 30 species, including rare ones like the Freckled Duck. Professor Kingsford reported over 100,000 grey teal ducks, 70,000 pink-eared ducks, and even breeding swans. He also noted an incredible sight of numerous swamphens and thousands of black-tailed native-hens.
This was the first bird survey in about 35 years, with birds serving as a crucial indicator of the system's health. As the water evaporates over the summer, the area is expected to become even more productive.
"All those invertebrates and fish that are in the water are going to be available to a whole range of different water birds," Professor Kingsford explained. "As it dries, it's got all of this moisture, so you get all the plants, animals and woodland birds and all those small animals will be able to take advantage of that high productivity that's in the system."
Cultural Significance and Heritage
Malyangapa man Mark Sutton highlighted the replenishment of many totem species due to the water. His totem, the bony bream, relies on these deluges for survival.
"Once that water arrives, either flowing down through systems or from the sky, those eggs hatch," he said. "Within weeks, those previously dry lakes can suddenly be full of fish."
The government's purchase of Narriearra Station has also provided Aboriginal people with access to the landscape.
NSW National Parks and Wildlife Service Ranger Emma McLean noted the area's rich Aboriginal cultural heritage, with numerous Indigenous artifacts found throughout the area.
"This place is so incredibly rich in Aboriginal cultural heritage," she said. "Everywhere you walk – especially once you get off tracks – everywhere you walk it's just all over the place."
They found examples of hearths, ancient cooking fires, and stone artifacts. A rare greenstone axe head, traded from Victoria, was also discovered on site.
But here's where it gets controversial... The preservation of these areas is crucial, but what about the impact of these large-scale environmental changes on the delicate balance of the ecosystem?
