Adding to Chatswood’s growing skyline, <a href="https://www.apartments.com.au/new-apartments/the-anderson-chatswood-54-56-anderson-street-chatswood-nsw-2067">The Anderson</a> is grounded in a simple principle: apartment living in a major centre does not have to come at the expense of space and outlook.

Set on Anderson Street in the heart of <a href="https://www.apartments.com.au/developments/chatswood-nsw-2067">Chatswood</a>, the new residential tower, a collaboration between developers <a href="https://www.apartments.com.au/developers/changfa-group">Changfa Group</a> and <a href="https://www.apartments.com.au/developers/huirong-group">Huirong Group</a> with architecture and interiors by <a href="https://www.apartments.com.au/architects/ajc-architects">AJC Architects</a>, will introduce 122 apartments that prioritise generous proportions, considered orientation, and a strong connection to the surrounding heritage precinct.

The design originated from a Design Excellence Competition, where AJC proposed a building that combines suburban-style apartment scale with the density expected in a transport-rich centre. The development will include more than 1,800 square metres of retail and commercial space at street level, landscaped communal roof terraces, and a ground-floor pocket park framed by canopy trees. Together these elements aim to create a building that integrates with Chatswood’s evolving streetscape while maintaining a strong residential focus.

[smartcode_project:default project_id=151353 project_image_fid=353250]

A key driver behind the architecture was the desire to deliver family-sized apartments rarely seen in the Chatswood market. The Anderson includes a mix of one to four-bedroom apartments, with around 35 per cent of the residences configured as three or four-bedroom homes. At the top of the building, two double-storey penthouses span approximately 200 square metres each, reinforcing the project’s emphasis on scale and long-term liveability for both downsizers and intergenerational households.

Orientation and outlook were central to the planning of the building. The apartments are positioned to maximise views to the north and east across Chatswood’s heritage precinct, with upper levels capturing glimpses of the Pacific Ocean. South-facing apartments gain distant views toward the Sydney CBD and Harbour Bridge, while the building’s configuration intentionally reduces western exposure at lower levels to minimise overlooking toward the nearby railway corridor.

The external design references the character of the surrounding conservation area without replicating it directly. A brick podium anchors the building to the street and introduces a series of architectural portals that draw inspiration from the nearby Chatswood Presbyterian Church. Above this base, the tower shifts to a lighter, more open expression defined by horizontal lines and carefully detailed balconies that balance privacy with outward views.

[smartcode_project:default project_id=151353 project_image_fid=353254]

Toward the top of the tower, AJC introduces a distinctive lantern-like element formed by sliding screens. These screens provide both solar shading and privacy while also creating a visual marker for the building within the Chatswood skyline. The feature reinforces the architectural intent of the project, a structure that is visually refined while still responding to the practical requirements of apartment living.

Inside the residences, interior architecture by Hayball focuses on clear spatial flow and practical everyday use. Open-plan living areas connect directly to large balconies, extending the internal living spaces outward and allowing natural light to move deeper into the apartments. Kitchens are designed as central working spaces with premium appliances and carefully selected materials, positioned to serve both daily living and entertaining.

[smartcode_project:default project_id=151353 project_image_fid=353256]

Bathrooms follow a similarly restrained design language, using refined fixtures and materials to create calm, functional spaces, while wardrobe areas adopt a gallery-style layout with integrated lighting and generous storage. These elements reflect a broader design approach that prioritises clarity, functionality, and durability over decorative gestures.

Positioned just a short walk from Chatswood Interchange, residents will have direct access to rail, metro, retail, and dining. The Metro extension allows travel from Chatswood to Martin Place in approximately 11 minutes, placing the CBD within easy reach for residents while maintaining the convenience of a walkable North Shore neighbourhood.

One-bedroom apartments at The Anderson start from $1,022,000.

How AJC designed The Anderson to bring oversized apartment living to Chatswood

<a href="https://www.apartments.com.au/developers/bridgewell-development">Bridgewell Capital</a> has lodged plans for a major mixed-use apartment development in the heart of Maroubra, seeking a significant uplift in height and density controls to deliver 120 apartments and a 120-place childcare centre near Maroubra Junction.

The State Significant Development application, filed through the NSW Government’s Housing Delivery Authority pathway, covers a 3,270 sqm amalgamated site at 251-257 Maroubra Road and 133-135 Garden Street. The proposal includes a concurrent rezoning that would increase the maximum building height from 12 metres to 35.6 metres and lift the floor space ratio to 4.02:1.

Designed by <a href="https://www.apartments.com.au/architects/bka-architecture">BKA Architecture</a>, the project would replace a mechanic’s workshop and several detached homes with a 10-storey residential building above four basement levels.

The scheme comprises 120 apartments, including 27 affordable housing units to be managed by a community housing provider for 15 years, alongside 203 basement car spaces and 92 bicycle spaces. A childcare centre occupying nearly 900 sqm of floor area would sit at ground level and be capable of accommodating 120 children and 22 staff.

<img alt="First look: Bridgewell plots 120 apartments and childcare centre in Maroubra town centre" data-entity-type="file" data-entity-uuid="038a0639-f9e4-4303-8fcc-d43e73fa480f" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Bridgewell%20pers.png?VersionId=eGBElxmNqJW.YF3JFYgHTnPgAstdyXR3" />

According to the Design Report, the project has been conceived as a “gateway proposal” that responds to Maroubra’s evolving urban character and its proximity to the town centre.

“Designed to complement the character of Maroubra’s town centre, this gateway proposal features a building scale that matches its surroundings,” the report stated.

“It integrates residential units above a ground-level childcare centre, fulfilling the strategic objectives of the Randwick City Council Masterplan.”

The apartment mix is weighted toward larger residences aimed at families and downsizers, reflecting changing demographics in the Randwick LGA and increasing demand for medium-density housing close to transport and amenity.

BKA Architecture said the proposal seeks to reinforce Maroubra Road as a civic spine while improving the pedestrian experience around the site through landscaping and upgraded public interfaces.

“The design capitalises on the following site opportunities: reinforcement of Maroubra Road as a civic spine, enhancement of pedestrian pathways and the public interface via new landscaping, and strong market demand for two and three-bedroom apartments to support families and down-sizers,” the Design Report noted.

<img alt="First look: Bridgewell plots 120 apartments and childcare centre in Maroubra town centre" data-entity-type="file" data-entity-uuid="ee509779-3c7e-4918-b03d-761c785459d0" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Bridgewell%20site.png?VersionId=eZC4Ruyn.C7O.Qwfr1SVeP5.ds1c5.66" />

The building has been designed with setbacks and articulation intended to transition between the commercial intensity of Maroubra Junction and the surrounding lower-scale residential neighbourhoods. Communal open space is proposed on level one, while upper-level apartments would secure views towards Port Botany, Maroubra Beach and Sydney’s eastern suburbs.

The development sits around 200 metres east of the Maroubra Junction intersection of Anzac Parade and Maroubra Road, within one of Randwick’s identified strategic centres. The site is close to Pacific Square Shopping Centre, major bus routes, schools, parks and future cycling infrastructure proposed under the Maroubra Junction Masterplan.

The Maroubra proposal aligns with broader NSW Government initiatives encouraging higher-density housing near established centres and transport corridors, particularly where affordable housing is incorporated.

Bridgewell is also working on a <a href="https://www.apartments.com.au/news/qld/goldfields-sets-the-stage-as-quartet-milton-launches">new 55-unit project in Killara</a>.

National diversified developer <a href="https://www.apartments.com.au/developers/goldfields-group">Goldfields</a> has launched its latest Brisbane apartment project, <a href="https://www.apartments.com.au/new-apartments/quartet-milton-33-manning-street-milton-qld-4064">Quartet Milton</a>, marking its entry into the sought-after inner-city suburb just two kilometres from the CBD.

The circa $100 million development will rise 18 storeys and deliver 131 apartments, offering a mix of one, two-, and three-bedroom residences.

Ideally located on Manning Street, Quartet residents will be within 300 metres of Milton Station, 500 metres from the Milton Ferry Wharf, and a short walk to Milton Markets, the iconic Park Road, as well as a range of breweries and cafés.

[smartcode_project:default project_id=108736 project_image_fid=367993]

Designed by architecture firm <a href="https://www.apartments.com.au/architects/rothelowman">Rothelowman</a> and brought to life by <a href="https://www.apartments.com.au/architects/cera-stribley-architects">Cera Stribley</a>, the building features a simple, gridded façade paired with generous glazing to enhance views, maximise aspect, and capture both sunrises and sunsets from within the apartments and their generously sized balconies.

Residents will have access to a 1,000 sqm rooftop, curated to balance wellness and entertaining, in response to increasing demand for wellness-focused shared spaces.

"We've approached Quartet Milton as a complete lifestyle offering, not just apartments, but a place where the design, amenities, and location all work together in a meaningful way," says Goldfields Managing Director Lachlan Thompson.

"Buyers are looking for that sense of confidence, knowing the vision has been carefully thought through not just by us as developers, but by all our consultants appointed to bring this together, and that it will be delivered to the standard they expect."

[smartcode_project:default project_id=108736 project_image_fid=368000]

Cera Stribley Co-Founder and Managing Principal Domenic Cerantonio said the rooftop is designed to feel like a place "you'd genuinely use every day."

"A 25-metre pool framed by city and mountain views, wellness areas, and private dining spaces for evenings with friends create a setting designed for year-round comfort and effortless Brisbane living."

[smartcode_project:default project_id=108736 project_image_fid=367999]

In addition to the 25-metre pool, the rooftop will include a sauna, cold plunge, fully equipped gym, and zen gardens, all complemented by panoramic views of the city and river.

While the building is expected to appeal predominantly to owner-occupiers, Goldfields anticipates interest from investors seeking strong rental returns, driven by the project's design, location, and the city's projected capital growth in the lead-up to the 2032 Brisbane Olympics.

<a href="https://www.apartments.com.au/developments/milton-qld-4064">Milton</a>, widely regarded as one of Brisbane's most desirable inner-ring suburbs due to its lifestyle offering and proximity to the CBD, has experienced a shortage of new apartment supply in recent years.

Goldfields is already active in the Brisbane residential market through its Ripley Valley masterplanned community, Hayfield. The 109-hectare neighbourhood is already home to more than 300 families and features a large community park.

Plans for the precinct include a 4 km running track, future schools, and retail and commercial amenities, all within a 35-minute drive of the Brisbane CBD.

Goldfields also plans to deliver a new mixed-use tower at 88 Robertson Street in Fortitude Valley, within the James Street precinct. The project will include 16,000 sqm of boutique commercial space, a level of wellness facilities, and a rooftop restaurant and event space, akin to Goldfields House in South Yarra, its flagship mixed-use development on Chapel Street, which is crowned by the Beverly Rooftop bar, one of Melbourne’s best-known venues.

Goldfields sets the stage as Quartet Milton launches

<a href="https://www.apartments.com.au/developers/stockland">Stockland</a> and Homes NSW have taken the next major step in the transformation of Waterloo Estate, lodging a Concept State Significant Development Application and concurrent rezoning proposal for the renewal of Waterloo South.

The proposal, now on public exhibition, outlines plans for around 3,300 new homes across the 12.3-hectare precinct. A minimum 30 per cent of residential gross floor area will be delivered as social housing, approximately 20 per cent as affordable housing, and a maximum 50 per cent as market housing. The redevelopment would more than quadruple the number of homes currently on the site and more than double the existing supply of social and affordable housing.

The renewal of Waterloo South forms the first stage of the broader Waterloo Estate transformation and is set to unfold over the next 10 to 15 years. The estate currently contains 750 social housing dwellings and 120 private homes.

<img alt="First look: Stockland and Homes NSW unveil plans for 3,300-home Waterloo South renewal" data-entity-type="file" data-entity-uuid="ba2da34b-171b-4ff1-b0c7-4baf0bce97f2" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Waterloo%20public.png?VersionId=S5apPKOqjPHJhk_SzCvdVPxsEBYs300o" />

The proposal, prepared by <a href="https://www.apartments.com.au/architects/sjb-architects">SJB</a> and Beam Planning, spans 10 street blocks bounded by Cope, Raglan, George, Wellington, Gibson, Kellick, Pitt and McEvoy Streets, directly adjoining the Waterloo Metro Station precinct and within walking distance of Redfern and Green Square stations.

Under the masterplan, building heights would range from two to 33 storeys, delivering approximately 282,485 sqm of residential floor space alongside at least 10,000 sqm of non-residential uses and a minimum 5,000 sqm of community space. The planning framework has been specifically structured to support the mixed-tenure outcome, with the residential gross floor area capped at a maximum 50 per cent market housing allocation.&nbsp;

The Urban Design Report describes the vision as creating “a unique and vibrant mixed-tenure housing precinct that supports the needs of the community and delivers much needed housing in response to National and State Government priorities.”&nbsp;

<img alt="First look: Stockland and Homes NSW unveil plans for 3,300-home Waterloo South renewal" data-entity-type="file" data-entity-uuid="6e1a6d8b-0626-4fa7-94fc-aa91c0af86dc" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/waterloo%20per.png?VersionId=duyiJTFOeezTNdM22leI3SoHuqnW6ZaY" />

A major focus of the revised proposal has been increasing the social and affordable housing component. The Minns Government increased the affordable and public housing allocation from 35 per cent to 50 per cent after coming to office in 2023.

Minister for Housing and Homelessness Rose Jackson said the changes were critical to maintaining Waterloo’s social diversity.

“When we came to government, we immediately reviewed the plans for the Waterloo renewal and boosted the number of public and affordable homes from 35 to 50 per cent,” Jackson said.

“This was a crucial step to ensure Waterloo remains a welcoming place for people from all walks of life to call home now and into the future.”&nbsp;

Minister for Planning and Public Spaces Paul Scully said the project would reshape the precinct for generations.

“This concept DA brings thousands of new public, affordable and market homes on the doorstep of the Waterloo Metro station another step closer to reality,” Scully said.

“Importantly, alongside the new homes the plan also proposes new open space where residents and the broader community can gather, relax and play.”&nbsp;

Stockland Managing Director and CEO Tarun Gupta said the project had been shaped around long-term liveability and community infrastructure.

“As delivery partner, Stockland is proud to be working with the NSW Government on the renewal of Waterloo South – a significant project with community at its heart,” Gupta said.&nbsp;

The planning documents place strong emphasis on “Designing with Country,” recognising the site’s location on Gadigal land. The masterplan incorporates new east-west pedestrian links, activated streetscapes, rooftop communal spaces, retail frontages, and landscaped public areas intended to improve permeability and community connection throughout the estate.&nbsp;

The proposal also seeks to establish a more flexible planning framework for future detailed SSDAs, including updated provisions for educational uses, creative industries, rooftop communal areas, and active frontages. A minimum seven per cent of residential floor space will be delivered as affordable housing managed in perpetuity by community housing provider City West Housing.&nbsp;

The Social Impact Assessment prepared by Urbis describes the renewal as one of Australia’s most significant public housing transformations, identifying substantial long-term positive impacts associated with housing supply, accessibility, public domain improvements, and community infrastructure.&nbsp;

Stockland and Homes NSW have already commenced the first stage of resident relocations, with some tenants moved into newly completed homes at Waterloo Metro Quarter and the Boronia development nearby.

Wind Farm

<html><body>
UBS Asset Management has sold their stake in Collgar Wind Farm, Western Australia's largest wind farms, to REST Industry Super.
REST had owned 40 percent of Collgar and have acquired UBS Asset Management's 60 percent stake.
The deal will make Collgar one of the largest Australian renewable energy projects directly owned by an Australian superannuation fund.
Rest has been involved with Collgar since construction began in 2010. 
Collgar generates, on average, between 40 and 50 per cent of the state’s renewable electricity. This is enough to power up to 170,000 average WA households per year and displace up to 690,000 tonnes of carbon dioxide emissions per year. 
<div class="page" title="Page 1">
<div class="layoutArea">
<div class="column">
The acquisition was negotiated by Rest’s internal investment manager, Super Investment Management. 
</div>
</div>
</div>
 George Zielinksi, chief investment officer at Super Investment Management, said the project is expected to continue to generate sustainable cash flows.
<div class="page" title="Page 1">
<div class="layoutArea">
<div class="column">
“Collgar Wind Farm is a premium infrastructure asset that has been delivering strong returns for Rest members", Zielinski said.
<img src="https://res.cloudinary.com/dz9xllyip/image/fetch/c_scale,w_580,q_auto:good/https://s3-ap-southeast-2.amazonaws.com/po.images/2019/6/24/Colgar%20Wind%20Farm%203.jpg" alt="">
"Renewable energy projects like this will continue to play an important role in Australia’s future.
“As an existing owner, Rest has been able to monitor and assess the wind farm’s operational performance since construction was completed in 2011. 
"Taking full ownership is a great opportunity to drive further value from the asset and strengthen Rest’s infrastructure portfolio. 
"We are confident it will help grow members’ retirement savings into the future.” 
Collgar is the largest wind farm in WA, built on 18,000 hectares of land with a total capacity of 206 Megawatts. 
Collgar generates, on average, between 40 and 50 per ent of the state’s renewable electricity, enough to power up to 170,000 average WA households per year and displace up to 690,000 tonnes of carbon dioxide emissions per year. 
The project holds a five-star Global Real Estate Sustainable Benchmark (GRESB) rating for 2018.

DomaCom have been selected by developers CWP Renewables and Partners Group as their partner to implement the community co-investment initiative of Sapphire Wind Farm in rural New South Wales.
The Sapphire Wind Farm, in Kingsland New England in Northern New South Wales, will be an Australian first for its community co-investment.
DomaCom's <a href="https://domacom.com.au/" target="_blank">fractional property platform</a> will allow local community members to invest alongside institutional investors.
The platform allows multiple investors to aggregate their investments into an asset, typically a real estate asset, but now also renewable energy projects.
Andrew Dickson at CWP Renewables, the company behind developing and constructing the wind farm, said DomaCom is a great fir for the community co-investment initiative.
"Their online platform makes it very easy for people to establish and manage their investment," Dickson said, adding that after testing the community's interest late last year, he was surprised with the level of interest.
“With over $7.3m of pledges received so far from the local community, we are pleased to now be delivering on our promise to the community, to open up the project for co-investment.”
Ross Laidlaw from DomaCom said the company are excited about the partnership.
“We are very excited to be partnering with CWP Renewables and Partners Group in the Community Co-Investment Sapphire Wind Farm. DomaCom has been a pioneer in fractional investment in Australia now in its 5th year of operation.
"The Sapphire Wind Farm Community Fund is a clear demonstration of the vision of DomaCom taking large institutional assets and breaking them down into fractional components to allow retail investors to obtain exposure to an asset class not previously available.”
Construction of the wind farm began in January, and the final turbine was installed in October. 
Ben Haan from Partners Group, the investment fund manager that co-owns the project, said community investment is integral to the business.
"What we are pioneering at Sapphire will be applied to future Grassroots projects, allowing our communities to share the benefits and to invest in Australia’s renewable energy future," Haan said.

GUEST OBSERVER
While Australia’s energy market operator continues its investigation into South Australia’s recent state-wide blackout, there are important questions being asked. 
For instance, was extreme weather the only cause? Has South Australia replaced fossil fuels with renewables too quickly?
And is the Australia’s Renewable Energy Target (RET) too ambitious all together?
It is impossible to find answers without understanding how the energy market works, and how replacing one source of energy with another actually happens. 
<h2>How does the market work?</h2>
Most Australians (barring the Northern Territory and Western Australia) get their electricity through the National Electricity Market. 
Suppose all the energy users, at a particular day and time, switch on lights, computers, industrial machinery, washing machines, vacuum cleaners, traffic control equipment and more. Added together, they determine how much energy is needed or demanded at that very point in time. 
On the other side of the poles and wires, different independent electricity generators – thermal, hydro, wind, solar – are offering energy to the market, each at a price enabling them to recover costs and make a reasonable profit. This is called bidding. 
Contemporary electronic technology allows for the wholesale market to take electricity and bids every five minutes, and allocate amounts accepted from the successful bidders. And who are those successful bidders?
All current bids are ranked by unit price. Allocation starts from the lowest-price bidder, then the second lowest one, and continues on until the current demand is met. The last accepted bidder’s price becomes the spot market price, and allows other successful bidders to make more or less profit.
<h2>How do renewables affect the market?</h2>
The main incentive policy for wind farms in Australia is the Renewable Energy Target (RET), which legislates that 33 gigawatt hours of electricity must come from renewable sources by 2020. As part of the RET, large-scale renewable energy generators (solar and wind farms) receive credits (certificates) for electricity they generate, which are then purchased by retailers to meet the target. 
This market is separate to the National Electricity Market (NEM) and acts as a second income source for renewable energy generators.
With this in mind, we have modelled what happens when wind energy is phased into the market based on five minute electricity market data for several years.
The running (marginal) cost of wind generators is zero (because wind is free), unlike traditional thermal technology (which has to pay for coal and gas). Subsequently, wind generators recover their fixed costs and obtain profit in the difference between marginal cost and market price based on “more expensive” bids. 
In the long run, wind generation decreases the market price through the bidding process. So with an increase in the energy volume generated by wind, the traditional sources are pushed out from the market. The chart below illustrates this process for South Australia. 
<a href="/images/2016/10/25/image-20161019-20308-xt2ui.jpg" target="_blank">Click to enlarge</a>
<h2><img src="/images/2016/10/25/image-20161019-20308-xt2ui.jpg" alt=""></h2>
Because their fixed costs can be recovered through the RET, wind generators can bid at near zero prices and completely eliminate traditional competitors. Therefore, wind generation can only naturally exist in the market if there are other, more expensive forms of generation to set the price. Otherwise wind farms could not recover their costs without the RET. 
This means that there is an optimal proportion of wind energy in the market, where more expensive thermal generators set the market price. 
If there is an optimum amount of wind energy in the market, this has important consequences for the RET. The target artificially increases the proportion of wind energy that can be sustained in the grid. While this may be the goal of the RET, without the incentive, wind capacity would eventually fall back to the market optimum. 
In practice, this would occur as wind farms reach their natural life of about 20 years and aren’t replaced. So the RET won’t maintain or increase wind energy in the market in the long term, unless the incentives continue indefinitely.
The current RET is legislated to 2030, with a target set for 2020. To encourage wind energy in the long term, it would be required, then, to support the RET by an ongoing financial inducement without a closing date. 
Without any financial inducement, wind farm developers would not increase capacity beyond the optimal point, and some thermal generation will continue to exist. Thermal generation can be completely excluded only if all the fixed costs of wind energy can be recovered through the RET. This is impractical and beyond the intentions of the policy. 
So as it stands, our modelling suggests the RET is not a good way to increase the amount of wind generation in the electricity network. However our conclusions are different for other renewable energy sources such as hydro, which also have near zero marginal costs but have much longer lifetimes.
Therefore, where and if possible, we need to use a mix of technology, rather than overemphasising wind generation technology.

Are wind farms messing up the electricity market?

<html><body>
GUEST OBSERVER
The debate about wind farms is clearly not over yet.
Last week Australia’s National Heath and Medical Research Council awarded A$3.3 million to fund two new health studies: one to measure the effect of infrasound on sleep quality, balance, mood and cardiovascular health; the other to determine whether low-frequency sound from wind farms can disrupt sleeping patterns.
Given the past few years of prickly wind turbine politics, this has predictably caused quite a stir.
On one side, the usual suspects sought to capitalise on the NHMRC’s announcement. Independent senator John Madigan called for a moratorium on new wind farms, wanting all projects to be put on hold as a “precaution”.
Coalition senator Chris Back leapt to support his call, perhaps unsurprisingly given that he (along with Madigan and fellow senators Nick Xenophon, David Leyonhjelm and Bob Day) have been described by Sydney University public heath professor Simon Chapman as “sworn enemies of infrasound".
In contrast, many in the scientific community expressed their disappointment at what they see as a waste of millions of research dollars. They referred to studies from around the globe that have consistently failed to find solid evidence for a connection between infrasound and poor health.
However, funding further research on the possible health impacts of wind turbines is consistent with the NHMRC’s own conclusions in a February 2015 statement, which said:
"Given [people’s] reported experiences [of ill health] and the limited reliable evidence, NHMRC considers that further, higher-quality research is warranted."
So the nation’s largest, most respected and most trustworthy medical research funding body actually agrees that more research is a good idea.
<h2>Down tools?</h2>
Tempting though it is, this piece isn’t about rehashing the current evidence of the health impacts – real or imagined – of wind turbines. That’s been done already and will clearly continue for a while yet.
What’s more interesting, to me at least, is this appeal for a moratorium, and the more general question of how useful a tool it is for making decisions about overtly science-based issues.
Madigan’s call is a typical invocation of the precautionary principle. This asserts that if there are reasonable (that is, evidence-based, scientific) grounds to believe something new might be unsafe – or at least presents risks that unacceptably outweigh the potential benefits – then we should not proceed with the new thing.
On the surface, it’s hard to argue with that.
But when it comes to wind turbines, there is nothing to suggest that Madigan, Back and like-minded folks will consider any level of risk acceptable.
Imagine for a moment that these new studies find no statistically defensible evidence to link infrasound to human ill-health. Will those calling for a moratorium accept the results and declare wind turbines safe (or at least safe enough to lift a ban)?
I suspect not. It looks to me as if what they are actually demanding is “proof of safety”, rather than evidence of “acceptable risk”. This is, of course, impossible. To use an oft-quoted example, we can’t prove that orange juice is 100 percent safe, yet it remains defiantly on our supermarket shelves.
I’d wager a year’s salary that Madigan and friends would declare any “acceptable risk” results to be insufficient, too short-term, or generally just biased and inadequate, and demand that yet more research is done.
The naysayers are not looking for counter-evidence to their claims, most probably because there are things about wind farms that they simply do not like. If they have been unswayed by the research showing no evidence of harm so far, it seems unlikely two more studies will change their minds. 
But what about us down at the science end of town? As noted on The Conversation last year by my colleagues Jacqui Hoepner and Will Grant, “if a credible, scientifically rigorous study were to show a link between wind turbine operation and health effects, it should absolutely be taken seriously”. Agreed!
So for argument’s sake, let’s imagine that these new studies do end up producing empirically valid results that clearly suggest that infrasound from wind turbines can cause people harm. Would we science-loving citizens be prepared to bow our heads and accept the evidence; to admit that Madigan and his cohorts did the right thing by calling for a moratorium?
I’d like to think that I would. But I also imagine myself demanding more research, and I’m confident most other science-positive folks would, too. In our defence, though, we would of course be looking for evidence confirming the existence and likely extent of the harm, rather than seeking proof of some mythical, absolute guarantee of safety.
<h2>Precautionary tale</h2>
So what good will more, precautionary-principle-inspired science do? In reality, probably very little.
For one thing, practical, policy-related action can rarely wait for “all” the evidence to be in before decisions are made and actions taken (assuming such a magical, perfect-evidence situation could ever arise). Invoking the precautionary principle is not likely to simplify this situation.
Far from making decisions more evidence-based, the calls for a precautionary approach are liable to entangle us more deeply in the politics of decision-making. It’s blisteringly naïve to believe that when applied “correctly”, the precautionary principle will refocus warring factions’ attention on noble considerations like gathering sufficient, acceptable evidence and using this to guide us to the most objective solutions.
In fact, it’s arguments over what constitutes the right kind – and sufficient amounts – of evidence that lie at the heart of such disagreements, not what the evidence itself shows. Many people call for evidence-based policy – but when it’s the evidence itself that is up for debate, it’s important (as my colleague Will Grant has quipped) actually to have evidence-based evidence.
So how will this issue play out from here? Here’s my guess:
• a moratorium will probably not be called
• the new research projects will be conducted
• based on current available evidence, they will probably find little to support the idea that wind turbines located more than than 1,500 metres from humans have measurable negative health effects
• scientists will say “I told you so”
• Senators Madigan et al, should they still be around, will call for yet more research.
