NSW National Parks Commits To Net Zero By 2028
Australia's First Renewable Energy Zone Declared
$13 Million To Halve Kooragang Island's Emissions And Support Jobs
ORICA PARTNERS WITH GOVERNMENT TO REDUCE KOORAGANG ISLAND SITE GHG EMISSIONS BY 48%
- The primary source of GHG emissions at the Kooragang Island facility is from the production of ammonia and nitric acid, both intermediaries in the production of ammonium nitrate. The production of nitric acid generates nitrous oxide as a by-product of catalytic oxidation of ammonia.
- In 2022, Orica will upgrade three nitric acid processing plants at its Kooragang Island site used in the production of ammonium nitrate, with technology designed to abate nitrous oxide emissions.
- This will be the first time the technology has been deployed in Australia, and is designed to deliver up to 95 per cent abatement efficiency from unabated levels. We expect to see a reduction in emissions by 567,000 tCO2e per year, and deliver a cumulative emissions reduction of at least 4.7 MtCO2e by 2030 based on forecast production.
- To facilitate the project, the New South Wales Government’s Net Zero Industry and Innovation Program will co-invest $13.06 million, together with Orica’s $24 million financed by a 5-year debt facility provided by the Federal Government’s Clean Energy Finance Corporation. The Clean Energy Regulator has also approved the project as eligible to generate Australian Carbon Credit Units.
- Kooragang Island employs 253 full time workers and contractors, and in 2019, $120 million was contributed to the New South Wales economy with over 1,500 additional jobs supported at state level. For every $1 million investment by Kooragang Island, an indicative $170,000 in additional activity occurs and 15 additional jobs are supported in the broader economy.
- Together with environmental outcomes, the project will ensure Orica’s domestic manufacturing operations remain competitive in a low carbon economy and continue to contribute to the local economy. Almost half of the $37 million project will be spent with local New South Wales suppliers. This builds on Orica’s history supporting local socio-economic development with two-thirds of suppliers to the site being located either in the Hunter Valley (38 per cent) or across New South Wales (28 per cent)
- Orica has recently announced a target to reduce scope 1 and 2 operational emissions by 40% (on FY19 levels), and an ambition to achieve net zero emissions by 2050iii.

Shorebird Identification Booklet
The Migratory Shorebird Program has just released the third edition of its hugely popular Shorebird Identification Booklet. The team has thoroughly revised and updated this pocket-sized companion for all shorebird counters and interested birders, with lots of useful information on our most common shorebirds, key identification features, sighting distribution maps and short articles on some of BirdLife’s shorebird activities.
The booklet can be downloaded here in PDF file format: http://www.birdlife.org.au/documents/Shorebird_ID_Booklet_V3.pdf
Paper copies can be ordered as well, see http://www.birdlife.org.au/projects/shorebirds-2020/counter-resources for details.
Download BirdLife Australia's children’s education kit to help them learn more about our wading birdlife
Shorebirds are a group of wading birds that can be found feeding on swamps, tidal mudflats, estuaries, beaches and open country. For many people, shorebirds are just those brown birds feeding a long way out on the mud but they are actually a remarkably diverse collection of birds including stilts, sandpipers, snipe, curlews, godwits, plovers and oystercatchers. Each species is superbly adapted to suit its preferred habitat. The Red-necked Stint is as small as a sparrow, with relatively short legs and bill that it pecks food from the surface of the mud with, whereas the Eastern Curlew is over two feet long with a exceptionally long legs and a massively curved beak that it thrusts deep down into the mud to pull out crabs, worms and other creatures hidden below the surface.
Some shorebirds are fairly drab in plumage, especially when they are visiting Australia in their non-breeding season, but when they migrate to their Arctic nesting grounds, they develop a vibrant flush of bright colours to attract a mate. We have 37 types of shorebirds that annually migrate to Australia on some of the most lengthy and arduous journeys in the animal kingdom, but there are also 18 shorebirds that call Australia home all year round.
What all our shorebirds have in common—be they large or small, seasoned traveller or homebody, brightly coloured or in muted tones—is that each species needs adequate safe areas where they can successfully feed and breed.
The National Shorebird Monitoring Program is managed and supported by BirdLife Australia.
This project is supported by Glenelg Hopkins Catchment Management Authority and Hunter Local Land Services through funding from the Australian Government’s National Landcare Program. Funding from Helen Macpherson Smith Trust and Port Phillip Bay Fund is acknowledged.
The National Shorebird Monitoring Program is made possible with the help of over 1,600 volunteers working in coastal and inland habitats all over Australia.
The National Shorebird Monitoring program (started as the Shorebirds 2020 project initiated to re-invigorate monitoring around Australia) is raising awareness of how incredible shorebirds are, and actively engaging the community to participate in gathering information needed to conserve shorebirds.
In the short term, the destruction of tidal ecosystems will need to be stopped, and our program is designed to strengthen the case for protecting these important habitats.
In the long term, there will be a need to mitigate against the likely effects of climate change on a species that travels across the entire range of latitudes where impacts are likely.
The identification and protection of critical areas for shorebirds will need to continue in order to guard against the potential threats associated with habitats in close proximity to nearly half the human population.
Here in Australia, the place where these birds grow up and spend most of their lives, continued monitoring is necessary to inform the best management practice to maintain shorebird populations.
BirdLife Australia believe that we can help secure a brighter future for these remarkable birds by educating stakeholders, gathering information on how and why shorebird populations are changing, and working to grow the community of people who care about shorebirds.

Free Training To Support Push For The Bush This Summer
November 5, 2021
Young people are being encouraged to skill up this summer and support the regions with 10,000 free training places across more than 800 courses now available to study.
The NSW Government today launched its Summer Skills program, offering free training in critical industries delivered by TAFE NSW and 120 registered training providers.
Deputy Premier and Minister for Regional NSW Paul Toole said in-demand short courses including construction, agriculture, hospitality, animal studies, shearing and wool harvesting, were available to study for free for people aged 16-24 years.
“We’re encouraging young people to go bush and combine learning with on-the-job experience this summer to support regional industries,” Mr Toole said.
“Now is the perfect time to get out, go and pick fruit in the regions, learn how to make a great coffee working for a local cafe or lend a hand to our farmers with free training funded by the NSW Government.”
Minister for Skills and Tertiary Education Geoff Lee said it was a great opportunity for young people to take advantage of new freedoms in NSW.
“It’s been a challenging period especially for our young people, which is why we’re committed to skilling them up to take on a job anywhere in NSW ahead of a bumper summer,” Mr Lee said.
“This is about giving school leavers a leg up in their career and the opportunity to put their skills to use after what has been a challenging year.”
Minister for Regional Youth Bronnie Taylor said the program will ensure young people have the confidence and skills they need for the next steps in their life.
“Our young people have really felt the impacts of this pandemic, whether it was having to learn from home, losing their part-time job or not being able to catch up with their mates,” Mrs Taylor said.
“This program is great news for our young people and will open so many future employment opportunities close to home, ensuring our rural and regional communities continue to thrive.”
Celebrity Chef and Thankful4Farmers ambassador Matt Moran said encouraging young people to explore the regions and learn new skills was a great solution to the skills shortages the regions are facing.
“This is a fantastic opportunity to have a fun-filled adventure in our backyard, while also making a real difference in the community, learning valuable skills and forging new friendships along the way,” Mr Moran said.
Summer Skills program is funded under the joint Federal and State JobTrainer program and is available to people aged 16 to 24 who have left school and are living or working in NSW.
Summer Skills short courses include:
- Animal Studies
- Process Manufacturing
- Transport and Logistics
- Shearing and Wool Harvesting
- Drone Essentials
- Care Roles Skillset

TAFE NSW Grows Workers To Stem National Skills Shortage
TAFE NSW is helping the arboriculture industry tackle a growing national skills shortage by training up and instilling a passion for the industry in workers like Sydney-based arborist Dalton Wills.
The 30-year-old from Coogee was working in the tree business as a labourer when he decided to upskill and enrolled in a Certificate III in Arboriculture at TAFE NSW Ryde.
He said joining the world-class horticultural college at Ryde led to a full-time position with Woollahra Municipal Council and gave him a deep appreciation for the beauty, environmental value, and public benefit of trees.
“Before, my work was just about making money, but the team at TAFE NSW helped me understand that it’s a really important responsibility to take care of trees and our public green spaces,” Dalton said.
“It’s given me a whole new perspective and it’s no longer just a job but a career that I love. Our team at Woollahra Council manages more than 20,000 trees. It’s our responsibility to care for them and ensure they remain healthy now and for future generations.”
Arboriculture Australia, the national peak body representing the industry, describes the current national skills shortage as “critical” while a Department of Education, Skills and Employment occupation report reveals only 15% of job vacancies in the industry are filled.
Dalton said TAFE NSW teachers taught him all the skills to step straight into work as well as a philosophical understanding of arboriculture, such as the broader context for why trees are so important to society.
“We learn to treat removal as a last resort because trees hold so much social, environmental, and economic value in the ground. It’s a very holistic approach to tree management,” Dalton explained.
“The teaching staff at TAFE NSW are experienced arborists with so much knowledge and practical skills. I graduated with all the skills I needed for a successful career as well as learning to understand and respect the role trees play in our city and our culture.”
TAFE NSW’s horticultural college enjoys a decades-old partnership maintaining some of Sydney’s most cherished public spaces, including the Royal Botanic Garden, the heritage-listed Rookwood Cemetery, Centennial Park, and the grounds of many major hospitals and institutions.
Head Teacher of Arboriculture at TAFE NSW Ryde, John Douglas, said the partnership gives students like Dalton the opportunity to grow their skills in some of the city’s most magnificent parks and gardens, embedding a deep sense of responsibility as they help shape Sydney’s green spaces.
“The city gets the tree work done for free while we have a perfect training ground for our students. It’s a wonderful symbiotic relationship,” Mr Douglas said.
“The students work on trees in places that are incredibly special to the people of Sydney, so they take pride in the work, and it helps build their skills, knowledge, and respect for the job.”

How much time should you spend studying? Our ‘Goldilocks Day’ tool helps find the best balance of good grades and well-beingDot Dumuid, University of South Australia and Tim Olds, University of South Australia
For students, as for all of us, life is a matter of balance, trade-offs and compromise. Studying for hours on end is unlikely to lead to best academic results. And it could have negative impacts on young people’s physical, mental and social well-being.
Our recent study found the best way for young people to spend their time was different for mental health than for physical health, and even more different for school-related outcomes. Students needed to spend more time sitting for best cognitive and academic performance, but physical activity trumped sitting time for best physical health. For best mental health, longer sleep time was most important.
It’s like a game of rock, paper, scissors with time use. So, what is the sweet spot, or as Goldilocks put it, the “just right” amount of study?
Using our study data for Australian children aged 11 and 12, we are developing a time-optimisation tool that allows the user to define their own mental, physical and cognitive health priorities. Once the priorities are set, the tool provides real-time updates on what the user’s estimated “Goldilocks day” looks like.
More Study Improves Grades, But Not As Much As You Think
Over 30 years of research shows that students doing more homework get better grades. However, extra study doesn’t make as much difference as people think. An American study found the average grades of high school boys increased by only about 1.5 percentage points for every extra hour of homework per school night.
What these sorts of studies don’t consider is that the relationship between time spent doing homework and academic achievement is unlikely to be linear. A high school boy doing an extra ten hours of homework per school night is unlikely to improve his grades by 15 percentage points.
There is a simple explanation for this: doing an extra ten hours of homework after school would mean students couldn’t go to bed until the early hours of the morning. Even if they could manage this for one day, it would be unsustainable over a week, let alone a month. In any case, adequate sleep is probably critical for memory consolidation.
Read more: What's the point of homework?
As we all know, there are only 24 hours in a day. Students can’t devote more time to study without taking this time from other parts of their day. Excessive studying may become detrimental to learning ability when too much sleep time is lost.
Another US study found that, regardless of how long a student normally spent studying, sacrificing sleep to fit in more study led to learning problems on the following day. Among year 12s, cramming in an extra three hours of study almost doubled their academic problems. For example, students reported they “did not understand something taught in class” or “did poorly on a test, quiz or homework”.
Excessive study could also become unhelpful if it means students don’t have time to exercise. We know exercise is important for young people’s cognition, particularly their creative thinking, working memory and concentration.
On the one hand, then, more time spent studying is beneficial for grades. On the other hand, too much time spent studying is detrimental to grades.
We Have To Make Trade-Offs
Of course, how young people spend their time is not only important to their academic performance, but also to their health. Because what is the point of optimising school grades if it means compromising physical, mental and social well-being? And throwing everything at academic performance means other aspects of health will suffer.
US sleep researchers found the ideal amount of sleep for for 15-year-old boys’ mental health was 8 hours 45 minutes a night, but for the best school results it was one hour less.
Clearly, to find the “Goldilocks Zone” – the optimal balance of study, exercise and sleep – we need to think about more than just school grades and academic achievement.
Looking For The Goldilocks Day
Based on our study findings, we realised the “Goldilocks Day” that was the best on average for all three domains of health (mental, physical and cognitive) would require compromises. Our optimisation algorithm estimated the Goldilocks Day with the best overall compromise for 11-to-12-year-olds. The breakdown was roughly:
10.5 hours of sleep
9.5 hours of sedentary behaviour (such as sitting to study, chill out, eat and watch TV)
2.5 hours of light physical activity (chores, shopping)
1.5 hours of moderate-to-vigorous physical activity (sport, running).
We also recognised that people – or the same people at different times — have different priorities. Around exam time, academic performance may become someone’s highest priority. They may then wish to manage their time in a way that leads to better study results, but without completely neglecting their mental or physical health.
To better explore these trade-offs, we developed our time-use optimisation tool based on Australian data. Although only an early prototype, the tool shows there is no “one size fits all” solution to how young people should be spending their time. However, we can be confident the best solutions will involve a healthy balance across multiple daily activities.
Just like we talk about the benefits of a balanced diet, we should start talking about the benefits of balanced time use. The better equipped young people and those supporting them are to find their optimal daily balance of sleep, sedentary behaviours and physical activities, the better their learning outcomes will be, without compromising their health and well-being.
