Climate change makes every risk factor for major bushfires worse, which means massive, intense fires will only become more likely.

The fate of deer carcasses is a crucial consideration in monitoring the success of future culling.
The NSW government has announced plans to remove feral deer from its list of official game animals. With careful monitoring, the resulting free-for-all could help curb their booming numbers.
The recall of several milk brands due to the possible presence of E. Coli is the second milk recall to affect Victoria and New South Wales this month.

VLocity trains run at speeds of up to 160km/h on four Victorian regional lines.
More than half a century after the first high-speed trains began running overseas, Australia is still waiting for the long-promised service. Right now, faster rail is a better short-term prospect.
A favourite argument of coal proponents is the idea that if their mine is knocked back, someone else will simply dig up coal elsewhere.

A NSW court's decision to rule out a coalmine on the basis of climate change could signal a turning of the tide in an arena where environmental litigants have previously struggled to gain traction.
Sydney’s iconic beaches are not yet part of a marine park.
The New South Wales government has turned its back on plans to create sanctuary zones covering 2.4% of waters around Sydney, despite evidence that these 'no-take' areas are crucial for protecting fish.
We need female role models in the NSW physics syllabus to normalise women in physics and encourage their engagement and further study.
The new physics syllabus for year 11 and 12 students in NSW contains no mention of specific women who have contributed to the field, nor their work.
Farmers need help to plan for droughts, not just to respond to them when things get desperate.
The government has offered emergency payments to drought-stricken farmers. But if we really care about them, we'll also invest in long-term drought resilience measures to reduce impacts.
Victoria has led the way in upgrading intercity rail services with medium-speed VLocity trains that have a cruising speed of 160km/h.
High-speed rail for Australia has been on the drawing boards since the mid-1980s but has come to nothing. Three states are developing medium-speed rail with federal funding, but NSW is missing out.
Health objectives are at last being integrated into all levels of planning in New South Wales, from cities and towns to local places and buildings.
The connections between city planning and health are many and varied, but getting health objectives integrated into all aspects of planning in New South Wales has been a long struggle.

The travelling stock routes are a precious national resource.
Australia's iconic stock routes are now public land, used for everything from conservation to recreation. A government review may change that.

Staffing rural schools has been an issue in Australia for at least 113 years. We need a fresh approach to tackle this persistent problem.
A ‘thinned’ landscape, which provides far from ideal habitat for many species.
Legal vegetation 'thinning' is contributing to high rates of land clearing, potentially causing problems for threatened species and ecosystems.
Our land-title system originated in the mid-19th century when Sir Robert Richard Torrens campaigned to reform Adelaide’s chaotic deeds-based land system.
