South-west Australia relies on groundwater for three-quarters of its water use. But a new study of the region’s caves has found a drying climate is having a dramatic impact on this precious resource.
Industry-funded research says existing models for potential maximum rainfall are out of date and suggests existing dams are at greater risk due to spillway inadequacy.
The growing threat of flash flooding as a result of more intense rapid rain bursts means the city needs to update its flood defences.
New research shows Australia experienced a number of megadroughts in the last 1000 years. We may be underestimating the severity of drought in Australia’s future.

By following moisture from the oceans to the land, researchers worked out exactly how three oceans conspire to deliver deluges of rain to eastern Australia.
To look inside a stalagmite is to look back in time tens of thousands of years to see how the Earth’s climate patterns have shaped the world we live in today.
Climate change and urbanisation are set to threaten groundwater drinking water quality, new research from UNSW Sydney shows.
Global water supplies are shrinking, even as rainfall is rising. The culprit? The drying of soils due to climate change.
A global analysis of rainfall and rivers by UNSW engineers has discovered a growing pattern of intense flooding in urban areas coupled with drier soils in rural and farming areas.
