Groundwaters in southern Western Australia have pH levels as low as 2.4 and salinities up to 28%, affecting bedrock and sediments. Human activities like mining and agriculture contributed to this extreme acidity, with deforestation and irrigation using desalinized seawater exacerbating the issue.
Queensland scientists have discovered five new species of antechinus, a 50% increase in diversity within the genus. Three of these species are already under threat from climate change, feral pests, and habitat loss, with one species destined for the threatened list.
Contagious yawning has been observed in budgies, a bird species for the first time, corroborating previous observations in social parrots. In experiments, yawns occurred more frequently when birds could see each other or viewed video clips of another bird yawning.
Residents and commercial users slashed their water use to 41 gallons per person per day by 2010, thanks to a culture shift among ordinary water users. An integrated water management system was key to Melbourne's success in reducing demand during the drought.

The study suggests a two-thousand-year delay in reef growth following sea level rise and flooding of pre-existing reefs.
Heavy rainfall from cyclone Quang affected western Australia, while a non-tropical system pounded the east coast, resulting in over 454 mm of rain in the Indian Ocean. In the Coral Sea, southeast Australia received above 356 mm of rainfall, causing widespread flooding and at least four reported deaths.
Tropical Cyclone Quang made landfall near Learmonth, Western Australia, as observed by NASA's Aqua satellite. The cyclone exhibited weakening trends due to increased vertical wind shear and interaction with the region's topography, leading to its expected dissipation within a day.
Tropical Cyclone Quang strengthened during the early morning hours of April 30, developing an eye and triggering warnings. The storm's sustained surface winds reached speeds of 67 mph, with strongest winds in the southern quadrant.

Scientists outline a six-point plan to restore the Great Barrier Reef through better policies on science, protection, and conservation. The plan includes measures to reduce stressors such as fishing, pollution, and coastal development, as well as transitioning away from fossil fuels and limiting coal port development.
Research suggests that accounting profession's negative stereotypes provide professional stability and exclusivity. The study uses 'commedia dell'arte' to analyze the role of stock characters in shaping career choices and perceptions of accountants. The authors argue that maintaining these stereotypes is beneficial for the profession.
Researchers at UC Riverside found that certain Dickinsonia fossils are incomplete due to ancient currents lifting them from the sea floor. The team measured the direction of missing parts and showed they aligned with features formed under wave action, indicating the fossils were not 'missing' but rather not preserved.
Fire management teams set fires to reduce hazardous fuels and protect human communities. Planned burns also help remove unwanted species, promote habitat for threatened species, and recycle nutrients back to the soil.
An international team of scientists found that global vegetation has increased by nearly 4 billion tonnes of carbon since 2003, driven by environmental and economic factors. The increase was largely due to tree-planting projects in China and changes in rainfall patterns in regions like Australia and Africa.
The expansion of no-take marine reserves in Australia's Great Barrier Reef Marine Park has led to an increase in fish numbers and sizes, particularly coral trout. However, researchers emphasize that no-take reserves alone are not enough to protect the reef from other threats such as pollution, sedimentation, and climate change.
A long-term study found that green zones have more than doubled coral trout biomass since the 1980s, while fished reefs experienced stable numbers and increases in large, reproductively-mature fish. Effective protection networks help reef fishes cope with stresses and maintain populations.
The Suomi NPP satellite captured an image of Tropical Cyclone Nathan's remnants, showing the storm had unraveled and most clouds were southeast of the center. Two large rainfall totals were recorded in the 24 hours prior, with 10.2 inches at Fanny Creek and 8.1 inches at Snowdrop Creek.
Tropical Cyclone Nathan's maximum sustained winds dropped to 30 knots (34.5 mph/55.5 kph) as it continued to move across land in the Top End of Australia's Northern Territory. The storm was weakening inland and had low potential for regeneration over the next few days.
Tropical Cyclone Nathan moved from Queensland to the Gulf Carpentaria and now crosses The Top End of Northern Territory. NASA's MODIS instrument captured images showing Nathan's western movement and second landfall near Arnheim Land.
A study will be conducted to understand how revalidation is carried out in comparable countries, with recommendations for models of implementation. The team aims to provide evidence to support future policy developments in Australian medical revalidation strategy.

Tropical Cyclone Nathan made landfall on March 19 at the Cape York Peninsula in northern Queensland, with sustained winds reaching over 30 meters per second. NASA's RapidScat instrument revealed the strongest winds were south of the center before landfall, and the storm was moving west across the peninsula.
A Monash University study reviewed over a million ICU patients in Australia and New Zealand, finding one in eight did not meet current sepsis criteria. The classic definition of sepsis may be missing critically ill patients, particularly the elderly or those on medications that affect heart rate or immune systems.
Researchers warn that localised issues such as water pollution and deforestation can exacerbate the effects of climatic extremes, reducing an ecosystem's capacity to cope with climate change. The authors call for enhanced local action to protect globally important ecosystems like the Great Barrier Reef and Amazon rainforest.
A new millipede species has been found in Launceston's city parks and reserves, with a known range of less than 12 square kilometers. The species, Tasmaniosoma anubis, does not appear to be threatened despite its small range.
