<a href="https://www.apartments.com.au/developers/draycon">Draycon Building</a> is nearing completion of Boutique Chevron Island, a 42-apartment development on the northern end of Chevron Island at 17–19 Parneno Street, with a limited-time offer of fully furnished apartments available.

Now more than 90 per cent complete, <a href="https://www.apartments.com.au/buildings/boutique-chevron-island-17-19-parneno-chevron-island-qld-4217">Boutique</a> has been shaped by one of the Gold Coast’s most tightly held island addresses, where riverfront outlooks and walkable access to Surfers Paradise converge.

For Draycon Building Managing Director Howard Dabit, the appeal of the site was immediate.

“I knew it was a good site as soon as I saw it,” Dabit said.

“The position and location on the north end of <a href="https://www.apartments.com.au/developments/chevron-island-qld-4217">Chevron Island</a>, the way the river swirls around the site basically from the north to the east, it feels like the site is surrounded by the water. The height that we’ve got and the aspect looking north is beautiful. Eighty per cent of the apartments are looking north so they get that drenching sunlight coming in.”

[smartcode_project:default project_id=89709 project_image_fid=360922]

That northern orientation places the development within a stretch of Chevron Island defined by open river aspects and skyline views, while remaining embedded in the suburb’s established village setting.

Chevron Island has increasingly drawn owner-occupiers seeking centrality without the intensity of high-rise beachfront living. Positioned at the geographical centre of the Gold Coast, the island offers direct access to both the beach and key cultural infrastructure while retaining a neighbourhood-scale character.

Connected by bridge to Surfers Paradise, Chevron Island offers walkable access to beaches, riverfront parklands and a revitalised foreshore boulevard animated by walkers and cyclists throughout the day. The Pacific Ocean is only minutes away, reinforcing the suburb’s dual river-and-surf identity.

At the same time, Thomas Drive forms the spine of the island’s village life, delivering cafés, wine bars, casual dining and everyday services within easy reach. Independent grocers, wellness operators and neighbourhood retailers contribute to a community atmosphere that remains distinct from the vertical scale of the beachfront.

[smartcode_project:default project_id=89709 project_image_fid=360915]

In the opposite direction, the Green Bridge links directly to HOTA – Home of the Arts – placing galleries, performance venues and parklands within walking distance. Weekly markets and major exhibitions draw visitors from across the region, while residents return to a quieter residential pocket at day’s end.

Public transport, including nearby bus routes and the G:link light rail corridor along the coastal spine, strengthens connectivity north and south. Griffith University, the Gold Coast University Hospital precinct and established private schools such as The Southport School are all within a short drive.

Ongoing investment across Surfers Paradise, HOTA and the broader Southport corridor has elevated amenity while preserving Chevron Island’s comparatively low-rise residential character. It is this balance, walkable village atmosphere paired with metropolitan-scale infrastructure, that continues to differentiate the suburb from higher-density beachfront precincts.

Boutique comprises just 42 residences, designed to maximise river and skyline outlooks within this tightly held island setting.

Boutique Chevron Island is slated for completion in April 2026, with prices starting from $1,220,000.

Sydney developer <a href="https://www.apartments.com.au/developers/deicorp">Deicorp</a> has secured planning approval for a $300 million residential development in Lindfield, marking the company’s second project on Sydney’s North Shore and its first on the Upper North Shore.

Located on Beaconsfield Parade and designed by DKO Architecture, the state significant development comprises three buildings of up to 10 storeys and will include 399 residences, including 59 affordable homes and 40 adaptable homes.

Residences will range in size from one, two and three bedrooms, with two-bedroom apartments accounting for over 60 per cent of the product make-up. Residents will have access to a broad suite of amenities, including a wellness area, indoor and outdoor recreational spaces, a pool, a gym, a community room and a golf simulator.

In line with Deicorp’s long-standing focus on creating transit-oriented communities, the project is located just 260 metres from the Lindfield Train Station, reinforcing its role in delivering well-connected housing close to established infrastructure, retail and local services.

The inclusion of affordable and adaptable housing supports greater diversity within the local market, while the mix of apartment types responds to demand from downsizers, young professionals and families seeking access to the Upper North Shore.

Deicorp Founder Fouad Deiri OAM said the approval represents an important milestone for both the company and the suburb

“This approval allows us to deliver well-designed homes in a location that is already supported by strong transport and community infrastructure," Deiri said.

"Our focus is on creating places that integrate into their surroundings and provide long-term value for residents, and the broader Lindfield community. Being within walking distance of the station ensures this project supports sustainable growth in the right locations."

Across its portfolio, Deicorp currently has 4,703 apartments under construction, playing a leading role in shaping connected, liveable communities across Sydney.

Its expanding portfolio of Metro-linked developments includes Tallawong Village, <a href="https://www.apartments.com.au/new-apartments/kings-bay-village-five-dock-53-75-queens-road-five-dock-nsw-2046">Kings Bay Village</a> in Five Dock, <a href="https://www.apartments.com.au/new-apartments/hyde-metropolitan-sydney-133-141-liverpool-street-sydney-nsw-2000">Hyde Metropolitan</a> in Sydney CBD, <a href="https://www.apartments.com.au/new-apartments/falcon-alexander-crows-nest-8-alexander-street-crows-nest-nsw-2065">Falcon &amp; Alexander</a> in Crows Nest and Showground Village, Castle Hill.

Deicorp purchased the Beaconsfield Paradise site last year. Construction is scheduled to commence in Q2 of 2026 and will be completed in 2029.

In a joint venture with The Trump Organization, Australia developer Altus Property Group has announced plans to bring a Trump International Hotel &amp; Tower to the Gold Coast, marking the first Trump-branded project in Australia.

"Trump International Hotel &amp; Tower, Gold Coast is our first official project in Australia and reflects our unwavering commitment to delivering world-class luxury experiences in iconic locations around the world," Eric Trump, Executive Vice President of The Trump Organization, said.

"This development exemplifies the Trump brand’s dedication to quality, sophistication, and unmatched service, and we are thrilled to bring this vision to the vibrant Gold Coast community."

The 91-storey building, which will become the tallest in Australia at 335 metres, will feature a&nbsp;285-room luxury hotel bearing the trademark Trump logo. It will also include 272 luxury residential apartments, a three-level podium with an exclusive Beach Club, and over 3,400 sqm of premium commercial, retail, and dining space, revitalizing the central Surfers Paradise precinct.

“Trump International Hotel &amp; Tower, Gold Coast will be a truly unique offering in the Australian market, bringing the prestige and allure of a world-class luxury brand,"&nbsp;Altus founder and chief executive David Young said.

"Altus Property Group is proud of its track record in delivering landmark developments across Australia, and our expertise ensures this project will be an outstanding success."

Trump Hotel heads for the Gold Coast to become Australia's tallest building

More than a century after the Corrimal Coke Works first opened in 1912, the industrial landmark that helped shape the suburb is being reinterpreted as a walkable residential neighbourhood, with Stage One of <a href="https://www.apartments.com.au/new-apartments/the-works-stage-one-27-railway-street-corrimal-nsw-2518">The Works</a> now underway at 27 Railway Street.

For 102 years, the site was central to <a href="https://www.apartments.com.au/developments/corrimal-nsw-2518">Corrimal</a>’s economic and social identity before operations ceased in 2014. Rather than erasing that legacy, developer Legacy Property has embedded it into the masterplan, retaining and reinterpreting elements such as the iconic 1912 brick chimney and sections of the original C1 Coke Oven Battery, alongside the adaptive reuse of the former powerhouse building.

Stage One will introduce 181 apartments across low-rise buildings, offering predominantly two and three-bedroom residences with completion targeted for mid-2027. The scale and configuration reflect a deliberate focus on owner-occupiers, targeting those seeking a lower-maintenance home in a prime location within the northern suburbs of Wollongong.

[smartcode_project:default project_id=143415 project_image_fid=359833]

Apartments have been designed to maximise natural light and cross-ventilation, with floor-to-ceiling glazing extending living areas onto generous balconies. Engineered timber flooring, induction cooktops and 900mm ovens in larger residences support everyday functionality, while two interior palettes allow buyers to tailor finishes to their preferences. The material selection draws on a restrained coastal language, intended to connect homes to their surroundings rather than compete with them.

The Works forms part of a broader 18-hectare masterplan that will ultimately deliver around 550 dwellings, new parks, and a heritage precinct celebrating the site’s past. More than seven hectares are dedicated to open space, including Southern Park and a Village Green with community gardens and recreation areas. The creek corridor is being rehabilitated with 150,000 native plantings, restoring biodiversity to the site and softening landscape.

[smartcode_project:default project_id=143415 project_image_fid=359841]

Positioned adjacent to Corrimal Station and within walking distance of Corrimal Town Centre, the precinct places daily essentials, rail connections and local retail within easy reach. Wollongong CBD, including the hospital, university and entertainment venues, sits approximately 6.5 kilometres to the south.

For buyers more familiar with North Wollongong, Corrimal offers a different proposition: a well-established coastal suburb framed by beaches to the east and the escarpment to the west, with a strong sense of local identity shaped in part by the former Coke Works. The Works seeks to reinforce that identity by creating a connected, walkable neighbourhood between coast and escarpment, rather than a standalone apartment complex.

Sustainability underpins the development approach. The Works is targeting Wollongong’s first 5-Star Green Star-rated community, with water-sensitive urban design, recycled materials and energy-efficient buildings integrated across the masterplan. For residents, these measures provide not only environmental benefits but also reduced operational costs and future resilience.

[smartcode_project:default project_id=143415 project_image_fid=359842]

With construction commenced and display materials available to view, prospective buyers can now engage more directly with the project’s vision, reviewing floorplans, material selections and the broader masterplan in detail. For many local homeowners weighing a move, the opportunity to experience how heritage, landscape and contemporary design intersect may help bridge the gap between familiarity and the next chapter.

As Stage One progresses toward its mid-2027 completion, The Works represents a significant chapter in Corrimal’s evolution, transforming a site that once powered local industry into a walkable residential precinct designed for its next generation of residents.

Legacy Property’s The Works reimagines Corrimal’s century-old Coke Works

When it comes to developing in Melb​ourne's Bayside region, <a href="https://www.apartments.com.au/developers/lowe-living">Lowe Living</a> knows exactly what buyers want.

With a longstanding presence in the area and a string of sell-out projects, Lowe Living consistently delivers developments that are as sought-after as their predecessors.

Their latest instalment is in <a href="https://www.apartments.com.au/developments/hampton-vic-3188">Hampton</a><a href="https://www.apartments.com.au/developments/hampton-east-vic-3188">&nbsp;East,</a> the same postcode where they have previously delivered Hampton Hill and Oceano. The developer-builder recently commenced construction on its newest project,&nbsp;<a href="https://www.apartments.com.au/new-apartments/marella-hampton-31-35-alicia-street-hampton-east-vic-3188">Marella</a>, a collection of 32 apartments just five minutes from the beach.

Site acquisition is paramount to success. Lowe Living rarely brings a building to market that isn’t within walking distance of essential amenities, whether it be the beach, a prominent retail strip, or a train station. Marella is no exception, located at its Alicia Street address, less than a kilometre from the retail heart of Hampton Street and Hampton Station.

[smartcode_project:default project_id=146197 project_image_fid=358495]

Equally important to Lowe Living is the architecture.

For Marella, they appointed <a href="https://www.apartments.com.au/architects/cera-stribley-architects">Cera Stribley</a>, who explains that the architectural vision was to create a contemporary reinterpretation of the Californian bungalow, a style that’s iconic to Hampton’s heritage.

"By borrowing, abstracting, and reinterpreting elements of this quintessential style, such as strong datum lines, articulated columns, exposed structures, and roof tiles, our design strikes a balance between modernity and familiarity," says Cera Stribley.

"This approach ensures that the development is not only visually appealing but also contextually sensitive, resonating with Hampton's existing architectural landscape."

[smartcode_project:default project_id=146197 project_image_fid=358499]

The building features terracotta brick, soft cream masonry, and exposed metal detailing, giving it a tactile presence that is intended to weather gently over time.

Internally, the focus on lasting quality continues, with two and three-bedroom residences anchored by sculptural stone kitchen islands, natural light, and clearly defined transitions between living, dining, and outdoor spaces.

The layouts have been carefully designed. Open-plan zones extend to private balconies, with light-filled interiors and generous kitchen proportions, supported by Miele wall ovens, induction cooktops, and integrated fridge-freezers. These are not small apartments rebranded as luxury; they have been designed at scale, with ample storage, hotel-style entry access, and secure basement parking provided as standard.

[smartcode_project:default project_id=146197 project_image_fid=358492]

At the uppermost level, Marella’s Signature Collection penthouses offer city or bay views, large entertaining terraces (some with outdoor spas), and elevated finishes, including fully wrapped stone kitchen benches and a Liebherr wine fridge.

Flexible room arrangements allow for a fourth bedroom or secondary living space, sought-after by both empty nesters who want the space when family visits and families with older children.

[smartcode_project:default project_id=146197 project_image_fid=358498]

A residents’ lounge on the ground floor reinforces the project’s small-community feel. With a fireplace, private dining area, and adjoining terrace, it’s one of several shared spaces that balance amenity with privacy and scale.

Construction has commenced, with completion expected in early 2027.

Lockout Laws

<html><body>
EXPERT OBSERVER
The New South Wales Bureau of Crime Statistics and Research (BOCSAR) <a href="https://www.bocsar.nsw.gov.au/Pages/bocsar_media_releases/2019/mr-Impact-lockouts-on-the-CBD.aspx" target="_blank">recently claimed</a> Sydney’s alcohol licensing regulations, commonly known as <a href="https://theconversation.com/au/topics/lockout-laws-26282" target="_blank">lockout laws</a>, reduced non-domestic assaults by 13% in the CBD.
Its calculation relied on a decision to allocate 1,837 of these offences to both Kings Cross and the CBD – that is, double-counting the data.
<a href="https://www.parliament.nsw.gov.au/ladocs/submissions/63631/Submission%20734%20-%20Centre%20for%20Translational%20Data%20Science,%20University%20of%20Sydney.pdf" target="_blank">Our analysis</a> found this decision was critical to the conclusion that assaults decreased in the CBD. For every other choice about the areas to which offences data were allocated and type of analysis we found no decrease.
<img src="https://images.theconversation.com/files/298452/original/file-20191024-119433-7qnb4k.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="">

<a href="https://www.parliament.nsw.gov.au/ladocs/submissions/63631/Submission%20734%20-%20Centre%20for%20Translational%20Data%20Science,%20University%20of%20Sydney.pdf%5D" target="_blank">Our findings</a> highlight an important question: how do the choices of data collection, pre-processing and analysis affect policy decisions?
The allocation of crimes to areas is just one of several choices made when using data to assess policy impacts. Other choices include how to measure violent crime, what time period to consider and the geographical extent of the areas to include. The question is: if other choices were made, would the results affect a <a href="https://www.propertyobserver.com.au/https://www.abc.net.au/news/2019-09-08/sydney-lockout-laws-rolled-back/11489806" target="_blank">decision to repeal or continue the laws</a>?
Our findings point to the need to follow a couple of principles when using data to inform policymaking. First, the institution that collects data and the institution that analyses the data should be independent of each other. Second, we need as much transparency about the data and its analysis as possible.
<h2>So what exactly did the analyses show?</h2>
BOCSAR chose to use monthly non-domestic assaults from 2009 onwards. There is nothing wrong with these choices, but others could have been made.
For instance, why from 2009 onwards, not from 2005? Why monthly, not daily? Why reported non-domestic assaults, not reported assaults causing grievous bodily harm? Why divide the area into the CBD and Kings Cross only?
One way of assessing the impact of such choices is to use different subsets of data, different types of data pre-processing and different statistical and/or machine-learning techniques. If the conclusion still remains the same, then our decision is robust to this source of variability. If not, we need to understand why.
For the Kings Cross precinct, the analysis by the Centre for Translational Data Science at the University of Sydney showed the conclusion remained unchanged irrespective of the frequency and period over which data were collected and the analysis performed. Non-domestic assaults had declined following the introduction of the lockout laws in 2014.
For the CBD the reverse was true. Only if we make exactly the same choices as BOCSAR, in particular allocating 1,837 crimes to both the CBD and King Cross, could we conclude non-domestic assaults had decreased very slightly.
Under all other variations of the analyses, including data, methodology and spatial allocation of that data, we found no decrease. Non-domestic assaults in the CBD had been decreasing since 2008 and, if anything, more slowly after the lockout laws took effect.
So why was the inclusion of 1,837 crimes so critical to the conclusions about the CBD?
Using data provided by BOCSAR, we plotted the most likely location of those 1,837 crimes. Figure 1 shows these crimes occurred mainly in Kings Cross, an area in which the crime rate had fallen since 2014. We say “most likely location” because we have yet to receive the additional data we requested from BOCSAR to help us locate exactly where these crimes occurred.
<a href="https://images.theconversation.com/files/298427/original/file-20191023-119429-qgf5xh.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/298427/original/file-20191023-119429-qgf5xh.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a> Counts of crimes (per SA1 region) that were assigned to both the CBD and Kings Cross. Centre for Translational Data Science, Author provided
With the removal of those 1,837 crimes from the CBD, we detected no decrease in non-domestic assaults. But BOCSAR apparently did. After removing those crimes from the CBD, BOCSAR released an <a href="https://www.bocsar.nsw.gov.au/Documents/BB/2019-Report-Effect-of-lockout-and-last-drinks-laws-on-assaults-BB142.pdf" target="_blank">updated report</a> to a <a href="https://www.parliament.nsw.gov.au/committees/listofcommittees/Pages/committee-details.aspx?pk=260" target="_blank">parliamentary inquiry into Sydney’s night-time economy</a>. This report claimed assaults in the CBD decreased by 4% (much less than the original 13%).
The committee then asked for our <a href="https://www.parliament.nsw.gov.au/ladocs/other/12591/Centre%20for%20Translational%20Data%20Science.pdf" target="_blank">comments</a>. We found the report did not provide a confidence interval for this decrease. Yet the report made a virtue of reporting uncertainty estimates for other quantities and elsewhere it claimed “statistically significant” results.
We replicated BOCSAR’s analysis and found the change in crime could have been as low as a 12% decrease and as high as a 6% increase. In other words, the result is “statistically insignificant”.
<h2>What are the implications for making policy?</h2>
Why does this matter? There are two reasons.
First, the danger in not explaining, quantifying and reporting uncertainty is that the public loses trust in data-driven policymaking. Only if conclusions acknowledge and explain the uncertainty inherent in inferring complex quantities from data can we make robust and explainable policy decisions that build trust with the public.
Second, if we don’t accept and report uncertainty we could stop looking for other explanations. We might then fail to achieve an outcome that everyone wants: a reduction in violence and a healthy night-time economy.
How do we proceed from here? We’d make two recommendations:
<ol>
<li>
The institution that collects and curates the data should be distinct, informed but independent from the institution/s that analyse the data.
</li>
<li>
There should be as much data transparency as possible, which would enable different groups to perform different types of analyses, using different sources of data.
</li>
</ol>
We are almost certain these different groups would produce different findings, but the subsequent discussion could provide insights that move us closer to more robust and acceptable policy decisions.

Sydney lockout laws review highlights vital role of transparent data analysis

<html><body>
The NSW Government is inviting community feedback on the second stage of its 24-hour economy liquor law reforms.
The draft Liquor Amendment (24-hour Economy) Bill 2020 aims to create risk-based liquor laws that support business.
Minister for Customer Service Victor Dominello said, “the proposals will help boost the state’s night time economy by removing outdated laws, simplifying licensing processes and creating a new incentives and sanctions system that rewards licence holders with a clear record.” 
“We want pubs, bars and hotels to hit the ground running on the other side, but we are mindful of how rules such as social distancing may need to be accommodated.”
Minister for Jobs, Investment, Tourism and Western Sydney Stuart Ayres said the hospitality sector is a significant employer and lifeblood for many communities, but has been dealt a devastating blow and brought to its knees due to COVID-19.
“COVID-19 has hit the hospitality industry hard and fast. We recognise the importance of streamlining the previously complicated legislation to make it easier for industry to get back on their feet as social distancing restrictions ease,” Mr Ayres said.
“There is now clearly a light at the end of the tunnel for our hospitality sector and this will give them hope for the future.”
Key proposals include:
A new incentives and sanctions system with ongoing fee discounts for licensed venues that maintain a clear record; Removal of outdated live music restrictions; Allow small bars to offer more family friendly services to customers, by permitting minors in certain circumstances; Reducing red tape by aligning liquor licensing and planning processes; and Enhancing same day alcohol delivery regulations.

With the removal of those 1,837 crimes from the CBD, we detected no decrease in non-domestic assaults. But BOCSAR apparently did. After removing those crimes from the CBD, BOCSAR released an <a href="https://www.bocsar.nsw.gov.au/Documents/BB/2019-Report-Effect-of-lockout-and-last-drinks-laws-on-assaults-BB142.pdf" target="_blank">updated report</a> to a <a href="https://www.parliament.nsw.gov.au/committees/listofcommittees/Pages/committee-details.aspx?pk=260" target="_blank">parliamentary inquiry into Sydney’s night-time economy</a>. This report claimed assaults in the CBD decreased by 4% (much less than the original 13%).
The committee then asked for our <a href="https://www.parliament.nsw.gov.au/ladocs/other/12591/Centre%20for%20Translational%20Data%20Science.pdf" target="_blank">comments</a>. We found the report did not provide a confidence interval for this decrease. Yet the report made a virtue of reporting uncertainty estimates for other quantities and elsewhere it claimed “statistically significant” results.
We replicated BOCSAR’s analysis and found the change in crime could have been as low as a 12% decrease and as high as a 6% increase. In other words, the result is “statistically insignificant”.
What are the implications for making policy?
Why does this matter? There are two reasons.
First, the danger in not explaining, quantifying and reporting uncertainty is that the public loses trust in data-driven policymaking. Only if conclusions acknowledge and explain the uncertainty inherent in inferring complex quantities from data can we make robust and explainable policy decisions that build trust with the public.
Second, if we don’t accept and report uncertainty we could stop looking for other explanations. We might then fail to achieve an outcome that everyone wants: a reduction in violence and a healthy night-time economy.
How do we proceed from here? We’d make two recommendations:
<ol>
<li>
The institution that collects and curates the data should be distinct, informed but independent from the institution/s that analyse the data.
</li>
<li>
There should be as much data transparency as possible, which would enable different groups to perform different types of analyses, using different sources of data.
</li>
</ol>
We are almost certain these different groups would produce different findings, but the subsequent discussion could provide insights that move us closer to more robust and acceptable policy decisions.

GUEST OBSERVER
The Sydney “lockout laws” have created significant debate about whether crime is being reduced, if it is being pushed into surrounding areas, and what the impacts are on local residents.
My research with Georgia Perks found that, despite reports of increased violence in these areas surrounding the lockout zone, the benefit outweighs the costs for local residents.
Our analysis of rental prices shows a small decline immediately after the lockout laws came into effect in February 2014. Since then, rents in these areas have outstripped other comparable areas in Sydney. 
This shows that residents of areas affected by the lockout are benefiting from new entertainment hubs and a nightlife economy that have sprung up since the lockout laws took effect.

<h2>The impact of the lockout laws on crime</h2>
The lockout law prohibits people entering hotels, registered clubs, nightclubs and karaoke bars after 1.30am in several areas of Sydney’s CBD (also called the Sydney Entertainment Precinct). These venues also have to stop serving alcohol after 3am. 
This law is a type of “geographically targeted crime control”. This means it targets “hot spots”, rather than the root cause of the crime.
If we are simply concerned about crime reduction, there are now several studies that show the lockout laws have substantially reduced the amount of alcohol-related violence and injuries in the targeted areas.
Restrictions on alcohol access have also been shown to work elsewhere, notably in Western Australia, Newcastle, and Queensland. Outside of Australia, this has been shown to work in the United States, Sweden, and the Netherlands.
So there is sufficient evidence to support the effectiveness of restrictions like the lockout laws in reducing crime in the targeted areas. But the research also shows increased violence in neighbouring areas, suggesting crime has moved. 
An important question is whether increased nightlife in these surrounding areas outweighs the cost of increased crime, and what is more important to local residents. 
<h2>Weighing up the lockout laws</h2>
A standard way to quantify the pros and cons of a policy like the lockout laws to local residents, and to weigh up factors such as crime and added entertainment venues, is to look at housing market data. 
When they make their decisions, potential buyers and sellers take into account information such as local crime and amenities (schools, entertainment venues, etc). Market prices then reflect this information and decision-making. If the average price in an area increases that means the value of living in that area has increased, taking all factors into consideration.
Using this logic, we studied rental prices in areas surrounding the target areas for the lockout laws. More data is available on rental prices in the short run than house prices, so it is useful to study the immediate market response to new policies. 
<a href="https://www.propertyobserver.com.au/images/2017/09/12/Screen%20Shot%202017-09-12%20at%208.55.04%20AM.png" target="_blank">Click to enlarge</a>
<img src="https://www.urban.com.au/images/2017/09/12/Screen%20Shot%202017-09-12%20at%208.55.04%20AM.png" alt="">
We collected prices both before and after the lockout law took effect, and compared areas in Sydney that have entertainment venues such as Newtown and Pyrmont (the “displacement area”) with areas that don’t, such as Alexandria, Chippendale, and Rozelle (the “control area”).
Our results show that there was a relatively small drop in rental prices of smaller dwellings (most likely to be on the main roads surrounding entertainment venues) in areas neighbouring the lockout, but this effect was weak and short-lived. This indicates that the market responded negatively to the increased crime being displaced from lockout areas, but this sentiment dissipated quickly.
On the other hand, we observe a greater, positive effect for larger dwellings. These are most likely to be off the main roads, having some separation from the noise and lights of the entertainment hubs but still near the nightlife. This phenomenon persisted throughout our study period, as shown in the following chart. 
The trend in the displacement area outweighed the trend in the control area. This difference after the implementation of the laws is statistically significant.
Overall our research strengthens the idea that the lockout laws are effective in controlling alcohol-fuelled crime and violence. Data show that crime and violence in displacement areas increased by a much smaller amount than the reduction in the lockout areas. This means residents in the displacement areas are actually better off due to new access to entertainment venues and the nightlife economy. 
However, this is not a full endorsement of the lockout laws. Neither our research nor earlier studies have investigated the business side of the lockout laws and the impact on the nightlife economy. There are likely to be forgone profits and lost jobs in targeted areas, as well as extra profits and new job opportunities in the displacement areas.
Similarly, we should study the gains and losses of non-resident late-night partygoers. The loss of nightlife and live entertainment culture in the target area was continuously highlighted in the debate. 
These concern have influenced a recent relaxation in the lockout laws for establishments that provide “genuine live entertainment”. Is this the right decision? We have a strong evidence of the effectiveness of the Sydney lockout laws in crime prevention. What we need is further evidence of the effects on these other groups.

Are residents better off under the Sydney ‘lockout laws’?

GUEST OBSERVER
Sydney’s lockout laws, as well as current and proposed restrictions in other Australian cities including Melbourne, Brisbane, Perth and Newcastle, are perhaps more about regulating people’s behaviours in cities than about liquor licensing.
Such knee-jerk responses to tidy up the mess of complex issues belie society’s need for diversity. They also neglect culture’s debt to the manifold possibilities of social behaviour in urban space.
Viewed as part of a broader historical pattern, such episodes of regulatory crackdown remind us that a seemingly purified city is not necessarily a healthy or diverse one.
<h2>Early steps</h2>
Australian cities have always been extraordinarily diverse places. Amid broader sociocultural and regulatory shifts, this diversity has produced instability as people from different backgrounds, ages, means, religions, sexualities and abilities have come together.
Some of the places where these instabilities play out are on the streets and in drinking establishments such as the café, bar and pub. People watch each other, ascribing meanings onto each other based on visual cues. Public drunkenness is one such cue.
An especially notorious instance was in London in the early 1700s during the gin craze. William Hogarth, the pictorial satirist of urban life, captured “Gin Lane” in 1751. On the streets of London, Hogarth moralised the issue, representing men wasting away rather than working, and a mother neglecting her children, allowing them to fall headfirst down the stairs. 
The issue was not alcohol itself (Hogarth thought beer okay), but rather the relationship between gin, nationalism and the lower classes, which apparently produced vice and neglect. The London authorities’ response was to regulate by introducing the Gin Acts, which raised prices and cut consumption.
In Australia, liquor licensing has also never operated in a historical or urban vacuum. English writer Richard Horne observed in Melbourne in the 1850s:
"The scenes that are witnessed, half-way up Bourke Street, in the direct line of both our Houses of Parliament [Spring Street], actually surpass anything in St Gile’s or Covent Garden [London] after dusk. It may seem strange that city authorities do not abate these disgraceful nuisances.
The “nuisances” he saw were young women. A typical mid-19th-century moralist, Horne believed – based on visual cues – that these women were “depraved”. Being an unaccompanied woman on the street was apparently linked to the dual vices of drinking and prostitution.
The solution Horne proposed was intervention by the urban authorities, to clear the streets for people that he perceived as more respectable.
<h2>The 20th century to today</h2>
Over the next century, the temperance movement sought to eliminate all alcohol consumption. So came about the pubs with no beer: the coffee palaces.
Across the Australian city, immaculate buildings were designed by leading architects to house these late-night venues, including the Federal Coffee Palace in Melbourne, the Sydney Coffee Palace in Woolloomooloo and the People’s Palace in Brisbane.
Urban improvement extended from buildings to the streets where freshwater fountains were constructed to quench the thirst of urban dwellers “in the interests of humanity and temperance”. Improving streets and cities for the greater good, such measures were typical of turn-of-the-20th-century social advocacy.
Young people were known to congregate around the fountains. Even during periods of restrictive liquor licensing, urban diversity has taken many forms, so long as alternative public places have been provided.
The next challenge for inner-city urban life related to liquor regulation was the early closing movement, coupled with rapid mid-20th-century suburbanisation that emptied out the Australian CBD outside the working week. The early closure of pubs led to the infamous six o’clock swil<a href="https://www.propertyobserver.com.au/https://journals.publishing.monash.edu.au/ojs/index.php/ha/article/view/347">l</a>.
Although temperance campaigners denied the existence of a “Pig Swill” during the NSW Royal Commission on Liquor in 1952, had the campaigners visited a pub or the street in the late afternoon their minds might have been changed. The refusal to visit the streets, to seek out visual cues, represented a form of wilful blindness typical across urban history.
At that time, hordes of pub patrons, predominantly men, entered the street on their way home to the suburbs. Outside Melbourne’s Young and Jackson pub on Swanston Street, opposite Flinders Street Station, men lined up to publicly urinate against the tiles. Walking past this prominent spot, opposite St Paul’s Cathedral, was no doubt an undesirable street experience.
Over the coming years every Australian city liberalised its licensing hours. Adelaide was the last to do so in 1967. These changes paved the way for the night culture familiar to us today.
Whenever authorities have regulated the city there have been unintended consequences. Heightening liquor regulation has for centuries been the immediate response of urban policymakers when confronted with people and behaviours deemed socially undesirable.
The overarching goal has been to impose a sense of order on the city and its spaces. But that happens at the expense of street life, public safety and social diversity. Shutting the pub early impacts urban life as a holistic ecosystem and, without viable public alternatives as in the past, this serves to eliminate difference on the street.
Cities thrive as messy places. No matter the underlying justification, to “lock out” the city is to diminish it.
