A heatwave across northern Australia comes as a shock to the system. The impacts of heat are worst in early summer when we’ve had less time to acclimatise, so it’s important to heed health warnings.
Northern Australia’s tropical savanna is one of the most fire-prone regions on the planet. We need to change the way we manage fires so we can help native wildlife come back from the brink.

Small mammals in northern Australia have been rapidly vanishing for the last 30 years, and scientists weren’t sure why. Now, a major new study found feral livestock are largely to blame.
The extent of this achievement is staggering, almost incomprehensible in a southern Australia context after the summer’s devastating bushfires.
Waters from the Herbert River, which runs toward one of northern Australia’s richest agricultural districts, could be redirected under a Bradfield scheme.

The ‘New Bradfield’ scheme seeks to revive a nation-building ethos supposedly stifled by bureaucratic inertia. But there are good reasons the scheme never became a reality.
The declaration of the 5 million-hectare Katiti Petermann Indigenous Protected Area around Uluru in 2015 helped take the land area of northern Australia in the hands of traditional owners to around 60%.

Expanding on sustainable practices in remote parts of Australia can deliver great benefits to both local Indigenous owners and national and global communities.
Could Darwin one day be home to more than a million people?

The government wants more people to live in Australia’s north. So we looked at three scenarios to increase the population and the results don’t always look good for the north.
Mangroves have died along a 1,000km stretch of coastline in the Gulf of Carpentaria.

Only about 5% of Australians live in the tropics, but it is not a mysterious or unopened land of limitless untapped potential. The ambition of northern development dates back to the 19th century.
Traditional hunting poses no threat to dugongs.

It sounds weird, but releasing small cane toads ahead of the main invasion front can help predators learn to avoid the biggest, most toxic ones. Here’s exactly how it works.

Australia’s Great Northern Savannas are the largest and most intact ecosystem of their kind on Earth. But they still face pressure from grazing, mining and agricultural expansion.
The Ord River was targeted for agricultural expansion in the 20th century.

Ever since British settlement, water rights in Australia’s north have favoured landowners over traditional owners, effectively locking Aboriginal people out of agricultural development.
