The new draft Victorian Koala Management Strategy will guide how koalas in Victoria will be conserved into the future − outlining ongoing actions to ensure their security, sustainability and health. Since the previous 2004 strategy was released, new issues impacting koalas have emerged and others have become more significant, including climate change, genetic diversity and extreme bushfires.

A dengue mosquito elimination program is gaining traction in Tennant Creek, a year since the dengue mosquito, Aedes aegypti, was found in the town. A team of five NT Health staff, known to the locals as the Mozzie Mob, are conducting property inspections to review backyard items that can hold water to treat them for mosquito eggs or larvae.

Tracy Jones, Desert Knowledge Australia. A group of local organisations and independent parties have joined forces in Alice Springs, NT, with the support of the Northern Territory Government, to address the town’s water future. The Talking Water Collective delivered a short, intense campaign during October-November 2021 to prompt awareness and build stewardship around the town’s water security, sharing key facts about water resources and consumption, and contributing to the NT's Strategic Water Plan.

After being nearly empty in early 2020, there’s been a remarkable turnaround in Murray–Darling Basin water storages following widespread rain throughout 2021, resulting in better water availability for towns, industries and the environment, and good cropping prospects in 2022.

For a second, I thought I had stumbled into the mellow haze of Woodstock, but this pungent aroma had no buzz or medicinal properties. It was all about fibre and the seed. Western Murray Land Improvement Group’s 7-hectare flood irrigation trial had over 70 attendees from as far away as Queensland. Five varieties were included in the trial to see what grows best in our region.

Koala habitat will be increased and water quality improved with the planting of 153,000 trees along Wivenhoe Dam to rehabilitate former grazing land ... The trees have been planted at seven sites on former grazing land and include eucalypts like Queensland blue gum, ironbarks, bloodwoods and grey gums, as well as rough-barked apple, river she-oak, and black tea-tree.

WA companies Aviair and HeliSpirit have partnered with global company Eve Air Mobility, part of the Embraer Group, to bring new zero-emission electric aircraft to WA within the next four years.

Geoff Helisma. Volunteer environmental organisation, Clarence Valley Environment Centre (CEC – established 1989), has released the results of a survey it commissioned, “to undertake koala scat detection [using a specifically trained] dog … in the Shannondale area, [in order] to assess koala presence/absence after the droughts, fires and floods”.

There have been increased reports of stable flies in the Shire of Gingin and other areas due to unseasonably wet conditions over winter and spring that enabled larval developmental sites to stay active for longer. Stable fly is primarily a pest of livestock, especially cattle and horses but it also affects humans, dogs and other animal pets.

Two localities in the Shire of Gingin have been added to the list of restricted movement zones to contain the spread of European house borer, which is a serious pest of pinewood.

A large male croc has been removed from the Endeavour River at Cooktown after it developed a taste for local dogs ... Due to its large size, the crocodile must be dealt with as an ‘iconic crocodile’ under Queensland’s conservation laws.

The Morrison Government has released a new five-year Action Plan to underpin the Threatened Species Strategy. This plan aims to coordinate effort for the recovery of 100 priority species and 20 priority places over the next five years with key targets to drive action.

A Charles Sturt University research project into planned burning ignites possibilities for conservation and restoration of critically endangered grassy ecosystems.

Chris Oldfield. Lucindale CFS group officer Patrick Ross last week pointed to black markings on a map in the incident control room of the town’s fire-fighting base. He turned to visiting SA emergency services minister Vincent Tarzia and said: “This is where the fatality happened.”

Research using effective survey methods shows that koalas are generally increasing with expanding National Parks and Lock It Up and Let It Burn conservation polices. The valleys are occupied by towns, so the koalas are moving in. Disease, dog attacks and road trauma are symptoms of irruptions, not causes of decline.

Friends of the Koala  welcomes  the federal government’s decision to up list koalas in Queensland, New South Wales  and the Australian Capital Territory from ‘vulnerable’  to ‘endangered’.  

The Morrison Government is boosting the level of protection for Koalas under National Environmental law, and will this week seek agreement from Queensland, New South Wales and the Australian Capital Territory on the National Recovery plan ... “The impact of prolonged drought, followed by the black summer bushfires, and the cumulative impacts of disease, urbanisation and habitat loss over the past twenty years have led to the advice." : Minister Ley.

Under the framework, biodiversity, unlike traditional farm commodities which are delivered to a buyer, will need to be maintained and/or established within the farm boundaries, much like carbon sequestration in vegetation and soil. There will be an ongoing relationship between the supplier (farmer) and purchaser to manage and report the status.
