The rise of global cities, metropolises that dominate their states, is exposing Australia's lack of metropolitan governments. It's time to restart the evolution of our states after a century on hold.
'Smart cities', featuring networks of automatic lights, video cameras and environmental sensors, have been hailed as an enhancement to urban life. But they are also tools of surveillance and control.
Australia's capital cities have collectively lost 30% of their stored water over the last six years. But this loss is not evenly distributed across the country.
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.
Many remote communities in Australia's north rely on bore water. But a new microbiology analysis suggests that the chemistry of untreated water can allow disease-causing bacteria to grow unchecked.
Because it happened within the Australian Plate rather than at a plate boundary, shockwaves from the quake travelled more efficiently to Darwin than to cities closer to the epicentre.
Darwin's climate is getting even hotter and it's one of the main reasons people leave the city. A lot more can be done, though, to make our tropical cities safe, cool and enjoyable.
After Cyclone Tracy, you'd expect Darwin of all cities to be ready for the next one. But as the clean-up after Cyclone Marcus continues, it's clear more must be done to increase the city's resilience.
