A who's who of Australian surfing, business and entertainment has emerged on title records following the completion of Esprit Rainbow Bay, the latest boutique beachfront apartment development by former professional surfer Paul Gedoun's S&amp;S Projects.

The completed project has attracted an enviable collection of owners, many with long-standing ties to the southern Gold Coast and the surf culture that has helped define Rainbow Bay and neighbouring Kirra for generations.

Given Gedoun's own background in surfing, it perhaps comes as little surprise that some of Australia's most recognisable surfers have chosen to buy into the development overlooking one of the country's most celebrated stretches of coastline.

Pezet Matheson directors Jayde Pezet and Todd Matheson launched the project in late 2021, and have managed the sales campaign all the way through to its sell-out and recent completion.

Former world champion Mick Fanning, who grew up in Coolangatta, secured an apartment in 2023. He paid&nbsp;$2.07 million. Last year he sold his Bilinga home for over $16 million.

Three-time world champion Joel Parkinson also purchased in the development, alongside big wave surfer Mark Mathews. Mathews bought the most expensive apartment in the building, spending just over $4 million.

Joining them is Rip Curl founder Doug Warbrick, whose company helped shape Australia's global surfing industry over the past five decades.

The appeal of Rainbow Bay has extended well beyond the surfing community.

International DJ Paul Fisher purchased an apartment through his investment vehicle, YLB Developments, an abbreviation of his trademark phrase "You Little Beauty".

The purchase comes as Fisher and his wife Chloe are developing their own luxury apartment project further north in Palm Beach. Their boutique beachfront development, Pescado, comprises just seven apartments on Jefferson Lane, which start from just shy of $6 million. The couple intend to retain the two-level penthouse as their Australian base between international touring commitments.

Melbourne Storm coach Craig Bellamy and his wife Wendy have also invested in Esprit, purchasing two apartments after spending decades holidaying on the southern Gold Coast. They also have a luxury apartment in Joe Adsett's Rockpool, less than 400m away from Esprit.

<h2>Boutique project draws owner-occupiers</h2>

Esprit launched in 2021 and sold strongly, with buyers drawn to its boutique scale, beachfront position and contemporary design.

The completed development comprises 94 apartments across 11 levels, offering expansive floorplans designed primarily for owner-occupiers rather than the investor market.

Crowning the building is Club Esprit, pitched as being the Gold Coast's first residential rooftop wellness centre. The roof features a&nbsp;25 metre magnesium lap pool, which is surrounded by wet daybeds and poolside cabanas,&nbsp;multiple barbecue areas,&nbsp;a yoga and relaxation play lawn, and a private dining room with a kitchen scullery, bar, lounges, and an outdoor terrace.

The wellness centre is&nbsp;fully equipped with a Technogym, ice bath, infra-red sauna, steam room, thermal room, and treatment room. The roof has views spanning&nbsp;Rainbow Bay, Snapper Rocks and the Pacific Ocean.

<h2>S&amp;S Projects continues to shape Rainbow Bay</h2>

S&amp;S Projects founder Paul Gedoun has become one of the key figures behind Rainbow Bay's evolution over the past several years.

After establishing S&amp;S Projects, Gedoun has focused on delivering lifestyle-driven apartment developments designed primarily for owner-occupiers seeking a permanent coastal home.

Esprit is Gedoun's third completed project in Rainbow Bay, following Flow and Awaken, both of which achieved record prices for the suburb.

He is now delivering <a href="https://www.apartments.com.au/new-apartments/radia-rainbow-bay-271-boundary-street-coolangatta-qld-4225">Radia Rainbow Bay</a>, a 38-apartment development on Boundary Street that is currently selling, and has no plans to leave the precinct anytime soon. S&amp;S Projects has also lodged plans for its fifth Rainbow Bay development, an 88-apartment project on Boundary Street featuring a strong wellness focus.

Nature Based Cities (NBC), the not-for-profit organisation focused on improving biodiversity and nature outcomes in urban development, has launched its latest industry design guidelines and accreditation framework, this time targeting precinct-scale residential communities.

The move extends NBC’s influence beyond its initial focus on medium and high-density residential developments. Several projects have already achieved NBC accreditation since the launch of its Medium &amp; High-Density Residential Guidelines in early 2025.

The expansion into masterplanned communities and new residential precincts reflects the growing need for stronger nature-positive benchmarks as Australia’s outer suburban growth corridors continue to expand at pace.

Paul Hameister OAM, NBC Founder and the Executive Chairman of Melbourne developer Hamton who itself leans heavily into nature and biodiversity in its developments, says the&nbsp;nature-first approach to mitigate the effects of climate change has become standard in other parts of the world such as the UK, but Australia is lagging.&nbsp;Australia’s environmentally sustainable design (ESD) rating tools have no minimum mandatory requirements for living landscapes.

“We’ve always wanted to do more, and we know other developers who want to do more, but the ESD rating tools just aren’t there,” Hameister says. “In Australia, you can have a five-green-star rated building that’s concrete and glass with not a blade of grass. 
 
“The focus is on reducing emissions, which is laudable, but there hasn’t been enough attention paid to protecting and re-establishing nature. We need both for the health of the environment and for communities.”

He says that having now&nbsp;made good progress in supporting developers of medium and high-density residential projects, NBC is now looking to bolster better nature-based decision-making and recognise developers of greenfield projects in the outer ring and large inner-ring brownfield precincts, who want to champion nature and living landscape as a defining feature.

Since 2022, the not-for-profit has sought to remove the roadblocks preventing developers from incorporating nature and living landscapes into their projects, shifting the conversation from the reduction of emissions and grey infrastructure, toward recognising nature as an essential infrastructure.

The New Communities Design Guidelines and Scorecard arm developers with the tools needed to deliver a nature positive outcome for their new communities. Intended to be adopted at the outset of the planning process, the guidelines are designed to help create communities that are cooler, healthier and more resilient while also enhancing social wellbeing and long-term economic value.&nbsp;

New Communities developers seeking accreditation will be independently assessed across a range of key criteria including ecology, tree canopy, biodiversity, and walkability. Once the masterplan is complete and submitted for approval, the scorecard is formalised based on proposed outcomes. Projects that meet the NBC criteria will receive either Commended or Exemplary accreditation outcomes, creating a clear benchmark for nature-positive new communities in Australia.&nbsp;

Janis Fischer, Director at Tract and NBC Advisory Council member, said the development of new communities in our suburbs can have a substantial impact on nature and biodiversity.

"By incorporating nature-based design principles at the inception of a project, developers and their design teams can achieve nature positive outcomes that are good for both people and the planet.’’&nbsp;

NBC accredited New Community projects will gain access to NBC branding and marketing tools to help communicate their nature-based credentials to purchasers and the broader market.&nbsp;

Nature Based Cities: A new Australian benchmark for developing nature-positive new communities

Apartment buildings are increasingly being designed around how people actually live day to day, not just how they want a building to look.

For buyers, that shift is showing up in practical inclusions that respond to changing habits. Work-from-home spaces, EV charging, wellness amenities, secure bike storage and parcel management are becoming part of the broader apartment conversation, reflecting a move toward buildings that reduce friction in everyday life.

Online shopping has become one of the clearest examples of that change.

Australians spent a record $82.6 billion online in 2025, with nearly one in four retail dollars now spent online. That has made parcel delivery a regular part of apartment living, rather than an occasional inconvenience.

For apartment residents, however, the delivery process can be less straightforward than it is for detached homes. Parcels may be left in lobbies, redirected to Post Offices, missed entirely, or placed under the responsibility of building managers and concierge teams.

That is why secure parcel infrastructure is increasingly being considered alongside more familiar apartment amenities.

<iframe allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen="" frameborder="0" height="315" referrerpolicy="strict-origin-when-cross-origin" src="https://www.youtube.com/embed/-VjjLwoViX0?si=A3k7ws9NX35Uac7_" title="YouTube video player" width="560"></iframe>

Australia Post Parcel Lockers offer one way to address the issue. When a parcel arrives, residents receive a notification through the AusPost app or SMS, then collect it using a QR code or one-time PIN. The parcel is kept secure, accessible and removed from common areas.

The broader Parcel Locker network now includes more than 1,500 locations across Australia, positioned at Post Offices, shopping centres, supermarkets, transport hubs and other accessible locations.

For new apartment projects, the relevance is clear. A building’s amenity offering is no longer only about lifestyle spaces, but also about convenience, security and functionality.

As buyer expectations evolve, secure parcel delivery is becoming part of the same design conversation as flexible working, sustainable transport and resident wellbeing.

It is one less thing for residents to worry about, and another example of apartment design adapting to the way Australians now live.

Apartment design is adapting to the way Australians shop

While school holidays and trips to Europe tend to define the winter property market, there's been no cold snap at <a href="https://www.apartments.com.au/new-apartments/the-walden-north-sydney-177-walker-street-north-sydney-nsw-2060">The Walden</a> in North Sydney.

Developer-builder&nbsp;<a href="https://www.apartments.com.au/developers/aland">ALAND</a> sold more than $35 million worth of apartments throughout June, including a $6.8 million apartment that now ranks among the highest apartment sales ever recorded in North Sydney.

SRM Residential agent Ben Stewart said buyer demand throughout June reflected a mix of improving market confidence and longer-term thinking from owner-occupiers.

"We're seeing strong demand from owner-occupiers who are taking a longer-term view," Stewart said.

"Many recognise the opportunity to secure an apartment in an iconic building and premium location while values remain attractive. They may initially lease the property, but the intention is to eventually move in themselves, rather than purchasing purely as an investment."

[smartcode_project:default project_id=134323 project_image_fid=367129]

Located at 177 Walker Street, The Walden will deliver 161 one, two, three and four-bedroom residences across a 30-storey tower designed by Rothelowman. Every apartment occupies a corner position, maximising natural light, cross ventilation and views across Sydney Harbour, the Opera House, Sydney Heads and the northern districts.

Rather than a traditional balcony, the residences feature winter gardens that seamlessly extend the open plan living areas, creating versatile spaces for relaxing or entertaining throughout the year. Floor-to-ceiling glazing draws in natural light while showcasing sweeping views from the building's elevated Walker Street position.

Every apartment features high-end Calacatta marble, bespoke joinery, and fully integrated appliances.

The larger residences have been planned with distinct entertaining and private zones, with many master suites positioned on corners to capture natural light and harbour views. Walk-in dressing rooms, freestanding baths and refined stone finishes reinforce the house-like feel that has resonated with downsizers and owner-occupiers.

[smartcode_project:default project_id=134323 project_image_fid=6393]

Rothelowman Principal Ben Pomroy said the project was designed to make the most of its unique position overlooking the harbour.

"The Walden is a celebration of all things beautiful, curated for those who expect nothing less than exceptional," Pomroy says.

"Meticulously designed entertaining spaces and light-filled living areas that capitalise on capturing the natural beauty of Sydney's iconic harbour."

Residents will also have exclusive access to The Pavilion, a dedicated amenity building featuring a rooftop pool, wellness studio, gymnasium, sauna, concierge service, residents' lounge, private dining spaces and work-from-home facilities.

[smartcode_project:default project_id=134323 project_image_fid=6402]

The project marks ALAND's first major luxury apartment development in Sydney's inner-city market after more than two decades delivering residential communities across Greater Sydney.

Founder and CEO Andrew Hrsto previously said the rarity of the Walker Street site made it an opportunity the company could not overlook.

"This is a rare opportunity to bring a truly exceptional project to life in one of Sydney's most iconic locations, and to showcase our craftsmanship and design expertise at a world-class level," Hrsto said.

[smartcode_project:default project_id=134323 project_image_fid=6383]

The Walden has been introduced to the market at a time when demand for living in North Sydney is at an all-time high. Billions of dollars have been invested in infrastructure, including the recently opened Victoria Cross Metro station, located just 300 metres from The Walden, providing residents with direct access to the Sydney CBD in just minutes.

Private investment has also transformed the area through the arrival of new retail and dining destinations, elevating the lifestyle offering in what was once considered primarily a commercial precinct rather than an aspirational residential address.

The Walden is currently under construction and is scheduled for completion in 2028.

ALAND records $35 million in sales in North Sydney as The Walden bucks quiet winter selling season

The long-awaited redevelopment of the former Eastlakes Shopping Centre site has reached a major milestone, with Conquest's plans for a new mixed-use precinct officially placed on public exhibition.

The State Significant Development Application would transform the 1.7-hectare site at <a href="https://www.apartments.com.au/new-apartments/19a-evans-avenue-eastlakes-nsw-2018">19A Evans Avenue</a> into one of Sydney's largest urban renewal projects, delivering 736 apartments above a new shopping centre anchored by Woolworths, alongside specialty retail, dining, commercial space and new public open spaces.

The public exhibition marks the next chapter for the project after <a href="https://www.apartments.com.au/developers/conquest">Conquest</a> acquired the stalled Stage Two development from Crown Group, who completed the first stage across the road prior to their voluntary liquidation.

<img alt="First look: Conquest unveils plans for 736-home Eastlakes Shopping Centre redevelopment" data-entity-type="file" data-entity-uuid="5fca22c5-d1ed-4e2c-8801-03f7df1eafc8" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/eastland%20podium.png?VersionId=uomwr41nF8CmLUZRDcu3mHQechlbxucS" />

&nbsp;

Designed by DKO Architecture, the proposal comprises four residential buildings ranging from 14 to 18 storeys above a two-level retail podium. The development would deliver 736 apartments, including 74 affordable homes, 215 Build-to-Rent apartments and 521 market residences. Provision has also been made for dual-key apartments, which could increase the total number of dwellings to 877.

At ground level, the shopping centre has been designed as the suburb's new meeting place, anchored by a full-line Woolworths and complemented by a curated mix of fresh food retailers, cafés, restaurants, health services and everyday convenience shopping. Generous pedestrian links and landscaped public spaces will connect the retail precinct through to Jack Mundey Reserve, creating a more walkable and connected neighbourhood.

Conquest CEO Michael Akkawi said the redevelopment was about far more than replacing a shopping centre.

"Eastlakes has been overlooked for too long, and this is the community’s moment. We are building a shopping centre and homes, a genuine heart for the suburb, and we genuinely want locals to help shape it."

"We enrich communities through the creation of homes, places, and experiences designed for life, built to last, and owner for generations. That starts with listening, so we warmly encourage everyone with a connection to Eastlakes to view the plans and share their thoughts."

<img alt="First look: Conquest unveils plans for 736-home Eastlakes Shopping Centre redevelopment" data-entity-type="file" data-entity-uuid="22f6fb20-54fb-4bd7-8a92-48fafdd00608" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/eastland.png?VersionId=cugp7s9hrMHGJJdYzkeAkrFoQgnF4GXf" />

DKO said the design had been shaped by the site's landscape setting and surrounding open space.

"Our vision for the site embraces its unique Bidjigal identity by blending the residential living with generous landscaping and a material palette inspired by the Bidjigal locality, and celebrating the panoramic views to Botany Bay and the wetlands reserves."

"Taking cues from Country, we seek to harmonise built form with the landscape and lightly touch the earth. By reconnecting, retaining and regenerating existing ecology, and weaving in natural elements, we can deepen our connection to Country."

The landscape strategy extends across the podium and rooftops, incorporating communal gardens, children's play areas, lawns, community gardens, family gathering spaces and extensive tree planting. New landscaped links will also strengthen the connection between the precinct and Jack Mundey Reserve, while publicly accessible open spaces have been integrated throughout the development.

The proposal builds on Conquest's broader placemaking strategy for the site. Through an ongoing partnership, local artist Joe Rashbrook has been appointed Urban Art Curator, working alongside young residents to transform the project's site hoardings into a public art gallery that allows the community to engage with the redevelopment before construction is complete.

Conquest has rapidly expanded its development pipeline since acquiring the Eastlakes site, with more than $6 billion worth of mixed-use projects now in planning across Sydney, including Stanmore, Castlecrag and Waterloo.

Conquest CEO Michael Akkawi said the redevelopment was about far more than replacing a shopping centre.

Hume Highway

<html><body>
Reigning world target crossbow champion Stuart Atkins and his wife Frances are selling their Hume property ahead of a relocation to the UK for their sport.
Those who have made the trip along the Hume Highway, past Yass and Bowning, may be familiar with the hill that sits atop the Hume Highway.
The site is on the market with real estate agents George Southwell and Dominic Johns, of Ray White Rural Canberra and Yass.
“It’s not too often that you get the opportunity to purchase such a landmark, that thousands of people drive past every day,” Southwell said.
“The views are amazing over the Yass Valley to the Brindabellas and beyond, overlooking the centre of our democracy.
“Few people know that a paddock on the property was once a World War 1 rifle range.
“The property has many interesting landforms, it is one of the only opportunities I have heard of to own a dormant volcano.”
<a id="LPlnk379381" href="http://ecomms.raywhite.com/collect/click.aspx?u=jRYOrR8N39R+6hBQZ7yXMt0Z3VIjNMZGSC5S/8OTYRL1I4RIyIuBgjh2KzJffc1Q&amp;rh=ff004b5478c644f4ab818579b2418862fc9da841" target="_blank" rel="noopener noreferrer" data-auth="NotApplicable">Bowning Hill</a> (pictured above) is 150 acres and the adjoining vacant block, <a id="LPlnk636818" href="http://ecomms.raywhite.com/collect/click.aspx?u=jRYOrR8N39QzG/Nyy8oj1JiKzK4T2JutIYGrUDz5CMLJvErwc0mbzq3lQxcEvdL5H1aezRyDZrsfYN4yg+AYwRfAH5E0IU+rWMh+ZAgTHTfl3x0STFT5sf8/7Shfsibg2oPaknQVQq8=&amp;rh=ff004b5478c644f4ab818579b2418862fc9da841" target="_blank" rel="noopener noreferrer" data-auth="NotApplicable">Northside</a> (pictured below) is 51 acres, with subdivision consent, subject to final registration.

The two lots will be sold to facilitate a relocation overseas for the vendors.
Atkins is returning to Germany this month to defend his world title.
“When we first bought the property in 1997, it was just one big block and we’ve created it into a small farm by making five paddocks,” he said.
“We improved the place with removal of weeds and made it quite accessible for the stock.
“It also has an abundant wildlife population too.
“We have sugar gliders, wombats, lizards, birdlife, kangaroos, rock wallabies and wedge tail eagles living on the hill, with echidnas in the garden digging their nests.”
Ray White marketing agent George Southwell said the likely buyer may be an introductory level farmer or a professional seeking a tree-change weekender.
“The Atkins’ have turned a vacant block into a true small farm and Frances has been leading the charge with fine wool production,” he said.
“Her most recent yield was 16.2 micron, which is an awesome achievement with their smaller line of sheep which are easily managed.
“The property includes a single stand shearing shed with covered room for roughly 100 head, however many uses could be adapted by new owners from an outdoor sports destination, suitable family property or even a great property to retire to.”
The Northside site is a blank canvas of bushland country set off the Hume Highway allowing for ease of access to Canberra in just under an hour and Yass in under ten minutes.
Bowning Hill includes a four bedroom and two bathroom home with dual occupancy potential. 
The owners have hosted the annual “Walk the Bowning Hill” charity fundraiser at their property for the past six years.
“The walk has raised $20,000 over six years,” Mrs Atkins said. 
“Locals love walking the hill, which has 360-degree views and on a clear day you can see the Black Mountain Tower in Canberra.
“The home is a four-bedroom PAAL kit home; with the highest point of the house being three metres off the ground.
“We’ve held some great parties on the big covered three-side deck and in the shearing shed.
“The gardens are all set up: mostly natives and some fruit trees.
“We have a beautiful aspect, with stunning views looking down the Murrumbidgee valley and the Brindabellas, but very secluded and serene.
“For winter there’s a beaut wood heater, and during the summer we use the evaporative cooler.”

World champ sells dormant volcano rural retreat 

<html><body>
A Melbourne based investor has paid $6.5 million on a 6.3% yield for a Campbellfield industrial facility with Hume Highway frontage.
Dawkins Occhiuto directors, Chris Jones and Walter Occhiuto brokered the deal.  
Located a short distance from the Metropolitan Ring Road, the 1608 Hume Highway property comprises a total building area of 4,949 square metres covering only 25% of the 16,550 square metre site.
It is leased to multinational tenant, Komatsu, on a seven year term expiring August 2020, at a current passing net rental of circa $411,000 per annum. 
Mr Jones said the Expressions of Interest campaign drew a strong field of local, interstate and off-shore buyers based on the property’s exceptional investment credentials.  
He said, “this property offered an excellent location and exposure right on the highway, a secure lease to a blue chip tenant, buildings and hardstand in very good condition and of high utility, high underlying land value, and significant future development upside with a low site coverage. It was hard to beat." 
“We are seeing strong yield compression, particularly for the best located, modern, industrial facilities with secure lease covenants, and that is likely to continue while industrial yields remain comparatively attractive vis-à-vis retail and office property, and while alternative assets classes are offering lower and/or more volatile return prospects,’’ Mr Jones added. 
The vendor was an interstate syndicator.

GUEST OBSERVER
It’s no secret that human development frequently comes at a cost to other creatures.
As our urban footprint expands, native habitat contracts. To compensate for this, most Australian governments require developers to invest in biodiversity offsetting, where habitat is created or protected elsewhere to counterbalance the impact of construction. 
Although biodiversity offsetting is frequently used in Australia – and is becoming increasingly popular around the world – we rarely know whether offsets are actually effective. 
That’s why we spent four years monitoring the program designed to offset the environmental losses caused by widening the Hume Highway between Holbrook and Coolac, New South Wales. Our research has found it was completely ineffective. 
Trading trees for boxes
The roadworks required the removal of large, old, hollow-bearing trees, which are critical nesting sites for many animals, including several threatened species. To compensate for these losses, the developer was required to install one nest box for every hollow that was lost – roughly 600 nest boxes were installed.
Many of the boxes were specifically designed for three threatened species: the squirrel glider, the superb parrot and the brown treecreeper. We monitored the offset for four years to see whether local wildlife used the nest boxes.
We found that the nest boxes were rarely used, with just seven records of the squirrel glider, two of the brown treecreeper, and none of the superb parrot. We often saw all three species in large old tree hollows in the area around the boxes we monitored.
Even more worryingly, almost 10% of the boxes collapsed, were stolen or otherwise rendered ineffective just four years after being installed. Perversely, we found that invasive species such as feral bees and black rats frequently occupied the nest boxes.
The offset clearly failed to deliver the environmental outcomes that were promised. Indeed, researchers have been concerned for some time nowthat offsetting can be misused and abused. 
What can be done?
It’s worth noting that research supports using nest boxes as a habitat replacement. However, they may never be effective for species such as the superb parrot. It’s not quite clear why some animals use nest boxes and others don’t, but earlier monitoring projects in the same area found superb parrots consistently avoid them.
Still, concrete steps can – and should – be taken to improve similar offset programs.
First, the one-to-one ratio of nest boxes to tree hollows was inadequate; far more nest boxes needed to be installed to replace the natural hollows that were lost.
There also was no requirement to regularly replace nest boxes as they degrade. It can take a hundred years or more for trees to develop natural hollows suitable for nesting wildlife. To truly offset their removal, thousands of boxes may be required over many decades.
Second, nest boxes clearly cannot compensate for the many other key ecological values of large old trees (such as carbon storage, flowering pulses or foraging habitat). This suggests that more effort is needed at the beginning of a development proposal to avoid damaging environmental assets that are extremely difficult to replace – such as large old trees.
Third, where it is simply impossible to protect key features of the environment during infrastructure development, more holistic strategies should be considered. For example, in the case of the woodlands around the Hume Highway, encouraging natural regeneration can help replace old trees.
Tree planting on farms can also make a significant contribution to biodiversity – and some of these may eventually become hollow-bearing trees. A combination of planting new trees and maintaining adequate artificial hollows while those trees mature might be a better approach.
Being accountable for failure
When an offset program fails, it’s unlikely anyone will be asked to rectify the situation. This is because developers are only required to initiate an offset, and are not responsible for their long-term outcomes.
In the case of the Hume Highway development, the conditions of approval specified that nest boxes were to be installed, but not that they be effective.
Despite the ecological failure of the offset (and over A$200,000 invested), the developer has met these legal obligations.
This distinction between offset compliance and offset effectiveness is a real problem. The Australian government has produced a draft policy of outcomes-based conditions, but using these conditions isn’t mandatory.
The poor results of the Hume Highway offset program are sobering. However, organisations like Roads and Maritime Services are to be commended for ensuring that monitoring was completed and for making the data available for public scrutiny – many agencies do not even do that. 
Indeed, through monitoring and evaluation we can often learn more from failures than successes. There are salutary lessons here, critical to ensuring mistakes are not repeated.
