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.
