An entity directed by HSN's Rafi Assouline and Rebel Property's Allen Linz has filed plans for an impressive new precinct in Woolloomooloo.

The major mixed-use development would transform a prominent William Street site into a new residential village anchored by affordable housing and a large public park.

The proposal, submitted as a State Significant Development Application, covers 164-172 and 174-194 William Street, a 6,398 sqm site between Forbes Street and Dowling Street on the southern edge of Woolloomooloo.

Designed by fjcstudio in collaboration with Bangawarra, Studio Bright and Tribe Studio Architects, the scheme would deliver 227 apartments across four residential buildings ranging in height up to 18 storeys, alongside retail space, public domain improvements and a new publicly accessible park.

It's another design scheme for Rebel, who took <a href="https://www.apartments.com.au/news/nsw/first-look-rebel-property-group-takes-woolloomooloo-precinct-to-nsw-government">concept plans to the NSW Gov late last year</a>.

The latest plans will be a mix of 167 build-to-sell apartments and 60 affordable apartments, with the affordable housing component representing 15 per cent of the project's gross floor area. The apartment mix includes 12 one-bedroom, 53 two-bedroom, 89 three-bedroom apartments and 13 penthouses, while the affordable housing component would comprise 42 one-bedroom and 18 two-bedroom apartments.

<img alt="Rebel" data-entity-type="file" data-entity-uuid="3b3d4553-8a8c-4af5-aa8c-519ffb1e28c6" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-06-12%20at%2011.20.12%E2%80%AFAM.png?VersionId=_Yb6ibN7eDnOtQjCNDK2eviORa4qzgv." />

Rebel Property is seeking to take advantage of the NSW Government's infill affordable housing bonus provisions under the Housing SEPP, which provide additional floor space and height in exchange for the delivery of affordable housing for a minimum of 15 years. The planning pathway allows a 30 per cent increase in floor space ratio and building height where 15 per cent of the development is dedicated to affordable housing.

&nbsp;

At the centre of the development is a 1,356 sqm sunlit public park designed to become a new community gathering space at the gateway to Woolloomooloo. The park would be complemented by a network of pedestrian laneways connecting William Street with the surrounding streets, improving permeability through what is currently a largely impermeable block.

<img alt="Rebel" data-entity-type="file" data-entity-uuid="257af931-a393-4007-8c6d-7219796df58d" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-06-12%20at%2011.20.51%E2%80%AFAM.png?VersionId=KAHy94GrhaReFsWTGDKfy39EDJ8gEEv4" />

The design team says the public domain has been heavily influenced by the site's topography and Aboriginal cultural heritage, drawing on the escarpments, gullies and landscape characteristics that historically defined the area before urbanisation. The landscape design has been developed in partnership with First Nations consultancy Bangawarra.

The project would be delivered across four separate buildings. The William Street East and William Street West buildings, designed by fjcstudio, would contain the majority of the apartments. Melbourne-based Studio Bright has designed the Forbes Street building, while Tribe Studio Architects is responsible for the Dowling Street building.

Rebel had secured approval for the concept plans late last year.

First look: HSN, Rebel, advances Woolloomooloo precinct plans

A locally heritage-listed furniture showroom on Water Street is set to become the centrepiece of a new mixed-use residential development as local developer&nbsp;<a href="https://www.apartments.com.au/developers/keylin-group">Keylin</a> seeks approval for <a href="https://www.apartments.com.au/new-apartments/lotus-on-water-street-290-water-street-fortitude-valley-qld-4006">Lotus on Water Street</a>, a 15-storey project on the Fortitude Valley side of Spring Hill.

The proposal spans 290 Water Street and 137-141 Warry Street, combining several properties into a 2,869 sqm site that sits between Fortitude Valley, Spring Hill and the rapidly evolving Victoria Park precinct. Keylin's plans would deliver 132 apartments alongside new retail, hospitality and commercial space, while retaining and repurposing the historic Brunswick Home Furnishers Showroom that fronts Water Street.

Designed by <a href="https://www.apartments.com.au/architects/jackson-teece">Jackson Teece</a>, Lotus on Water Street comprises a 12-storey residential tower rising above a three-storey podium and communal rooftop terrace. The development includes 76 apartments classified as multiple dwellings and a further 56 units proposed as short-term accommodation, designed to be flexibly used as either accommodation or permanent residences. The apartment mix comprises six one-bedroom, 54 two-bedroom and 16 three-bedroom homes.

<img alt="First look: Keylin unveils heritage-led Lotus on Water Street tower in Fortitude Valley" data-entity-type="file" data-entity-uuid="9822bb79-6c49-49c9-95ba-319e8c8d81c3" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/fortitude%20valley%20front.png?VersionId=ioW8zbN4UVebbLetTFuv92t.HkdgfR5e" />

Residents would have access to an extensive rooftop recreation level spanning more than 1,200 sqm of communal open space. Plans include a pool, gym, sauna, infrared sauna, yoga area, library, private dining room, barbecue facilities and landscaped entertainment spaces, making the rooftop the project's largest shared amenity offering.

At street level, the proposal focuses on the adaptive reuse of the heritage buildings along Water Street, where 518 sqm of retail and commercial space is planned across shop, office and food and drink outlet uses. A permeable residential lobby would be positioned between the retained heritage buildings, creating a pedestrian connection between the historic streetscape and the new tower behind.

<img alt="First look: Keylin unveils heritage-led Lotus on Water Street tower in Fortitude Valley" data-entity-type="file" data-entity-uuid="269cf3e0-7d13-48bf-a318-05a00deb5c10" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/fortitude%20valley%20podium.png?VersionId=DLXmTCLsp6GOcLpQ0h.0z7wKCw59EhN_" />

The heritage retention strategy is central to the scheme. The development application notes that the Brunswick Home Furnishers Showroom and adjoining heritage buildings will remain, with only non-significant structures on the site earmarked for removal under a previously issued Heritage Exemption Certificate. Levels one and two of the new podium are recessed behind the heritage façades to maintain their prominence within the streetscape.

Jackson Teece has drawn inspiration from the site's manufacturing history when designing the podium. The planning documents state that the façade incorporates perforated metal screening that references the woven and rattan furniture historically produced on the site. Cascading and climbing plants are integrated throughout the podium to soften the building's presentation and screen parking levels behind. The landscape strategy also informs the project's name, Lotus on Water Street, drawing on the historic Spring Hollow waterholes that once ran through Spring Hill and the blue water lilies associated with Meeanjin, Brisbane's traditional name.

The proposal also incorporates the neighbouring property at 141 Warry Street, currently occupied by a healthcare service. The existing building would remain, with nine dedicated parking spaces allocated within the new development to support its ongoing operation. In total, Lotus on Water Street proposes 117 car spaces, including 110 resident spaces and seven visitor bays, alongside 100 bicycle spaces.

<img alt="First look: Keylin unveils heritage-led Lotus on Water Street tower in Fortitude Valley" data-entity-type="file" data-entity-uuid="70cf07bc-4fd8-4e70-92dd-be8b21c4e4f0" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/fortitude%20valley%20site.png?VersionId=txlxrJImM0Sm_vTzHVKh5DDUkyL_CiiA" />

The site sits within the Spring Hill East Precinct of the Spring Hill Neighbourhood Plan and is positioned around 650 metres from both Fortitude Valley Station and Exhibition Station. It is also within walking distance of the King Street precinct, Royal Brisbane and Women's Hospital, Herston Quarter and Victoria Park, which is earmarked to become a major venue precinct ahead of the Brisbane 2032 Olympic and Paralympic Games.

Planning documents describe the location as a key gateway between Spring Hill and Fortitude Valley and highlight the area's increasing importance as new transport infrastructure and Olympic-related investment reshape Brisbane's inner north. The development team argues the project will contribute additional housing supply while activating a section of Water Street that has historically received less investment than other parts of the Valley.

Keylin has become increasingly active across Brisbane and southeast Queensland, assembling sites in strategic inner-city locations. They are currently selling and delivering <a href="https://www.apartments.com.au/new-apartments/oria-spring-hill-447-gregory-terrace-spring-hill-qld-4000">Oria Spring Hill</a>, just over 140 apartments due for completion in 2027.

Roseville is poised for a wave of new apartment development following the NSW Government's rezoning of land around Roseville Station under its Transport Oriented Development program.

The new planning controls have unlocked significant development potential within walking distance of the station, with a number of sites expected to be amalgamated and redeveloped in the coming years as developers seek to take advantage of the increased density allowances.

One of the more restrained developments in the precinct, and set among the first to be delivered having commenced well before the recent changes, is Hyecorp's Juliet. The boutique apartment project is already well under construction and remains on track to welcome residents by the end of the year, offering a markedly different proposition to many of the larger-scale developments now likely to emerge across the suburb.

[smartcode_project:default project_id=7395 project_image_fid=278194]

<a href="https://www.apartments.com.au/new-apartments/juliet-roseville-64-pacific-highway-roseville-nsw-2069">Juliet</a> will comprise just&nbsp;34 one-, two-, and three-bedroom apartments opposite Roseville Station. For Hyecorp, which has delivered projects across Sydney's Lower North Shore for more than three decades, Roseville presented a rare opportunity to address a growing gap in the market.

"<a href="https://www.apartments.com.au/developments/roseville-nsw-2069">Roseville</a> has long been one of the North Shore's most tightly held and desirable suburbs, offering a unique combination of village charm, established greenery, excellent transport connections, and proximity to some of Sydney's best schools and lifestyle amenities," Hyecorp said.

"We recognised a growing demand from local homeowners seeking to downsize without leaving the community they have built their lives around. The location presented a rare opportunity to create homes that cater specifically to that buyer profile."

[smartcode_project:default project_id=7395 project_image_fid=278196]

The six-level development has been designed by <a href="https://www.apartments.com.au/architects/pbd-architects">PBD Architects</a> as a collection of residences that feel more like homes than apartments. The brief centred generous floorplans, abundant natural light, quality finishes, and strong connections to outdoor space.

PBD Architects drew inspiration from Roseville's established garden suburb character, creating a building that sits comfortably within its surroundings rather than dominating them. The architecture incorporates natural materials, soft forms, layered landscaping, expansive balconies, and generous setbacks to strengthen the connection between residents and the suburb's leafy environment.

"The focus was on designing spacious, house-like residences for discerning owner-occupiers and downsizers who wanted to remain on the North Shore without compromising on comfort, privacy, or design," PBD said.&nbsp;

"Every apartment was to feel considered, timeless, and highly functional."

[smartcode_project:default project_id=7395 project_image_fid=278195]

Inside, residences feature engineered timber flooring, stone kitchen benchtops and splashbacks, integrated Fisher &amp; Paykel appliances, ducted air conditioning, and large outdoor entertaining areas designed to take advantage of district and treetop views.

Residents will also have access to a rooftop barbecue and lounge area, alongside practical amenities including parcel lockers, EV charging capability, bicycle storage, a dog wash bay, and a basement car wash facility.

The majority of purchasers so far have been local owner-occupiers from Roseville, Lindfield, Chatswood, Killara, and the broader Upper North Shore, many of whom are transitioning from larger family homes.

"Buyers are looking for spacious, house-like apartments that allow them to downsize without feeling like they are sacrificing comfort or functionality," Hyecorp noted.

"They value large kitchens, generous living areas, ample storage, quality finishes, secure parking, lift access, and low-maintenance living."

[smartcode_project:default project_id=7395 project_image_fid=278204]

Juliet sits directly opposite Roseville Train Station and within walking distance of Roseville Village, while Chatswood's retail and dining precinct is only minutes away. The development is also surrounded by some of Sydney's most established schools, including Roseville College, Ravenswood, Pymble Ladies' College, and Knox Grammar, as well as nearby parklands and golf courses.

Juliet is currently more than 75 per cent sold ahead of its anticipated completion in late 2026.

Sherpa Property Group has unveiled the third instalment of its Flourish series, securing full approval for the two-tower, $500 million Flourish Soleira development in Palm Beach.

<a href="https://www.apartments.com.au/new-apartments/flourish-soleira-1150-1154-gold-coast-highway-palm-beach-qld-4221">Flourish Soleira</a> will rise from a prominent site in the commercial heart of Palm Beach, the long-time home of Cash Converters and a range of local retailers.

The project will introduce a new retail and dining precinct at ground level, beneath 286 apartments.

[smartcode_project:default project_id=150017 project_image_fid=370959]

“We’re very committed to not only providing affordable residential offerings that are much needed in Palm Beach, but also delivering a vibrant new commercial heart that complements the extraordinary growth of the southern Gold Coast,” Sherpa Property Group founder Christie Leet said.

The development will sit under Sherpa's Flourish brand, which is aimed at providing a pathway into the beachside suburb for locals, first-home buyers and downsizers. In a move designed to assist first-home buyers entering the market, Sherpa has reserved all one and two-bedroom, one-bathroom apartments exclusively for eligible first-home buyers.

[smartcode_project:default project_id=150017 project_image_fid=370964]

“Our vision through Flourish is to create a vibrant retail and lifestyle focal point within the Palm Beach centre zone, delivering thriving communities underpinned by lifestyle-rich locations,” Leet said.

“So far, Flourish has been an incredible success, and we hope to carry this momentum as we progress the next two Flourish projects in Palm Beach.”

[smartcode_project:default project_id=150017 project_image_fid=371430]

Located across 1150-1164 Gold Coast Highway and 3 Sixth Avenue, the development will comprise two towers. The northern tower will deliver 154 apartments, while the southern tower will add a further 132 residences, helping address ongoing demand for new apartments in the tightly held coastal suburb.

Flourish Soleira will also feature the most extensive rooftop amenity offering ever delivered in Palm Beach.

The two towers will be connected by a skybridge, with residents gaining access to a rooftop recreation deck featuring a full-width swimming pool, hot and cold plunge pools, wellness spaces, a gymnasium, private dining facilities, massage treatment rooms, barbecue areas, a basketball court, golf simulator, indoor and outdoor dining spaces, sun lounges and extensive landscaping.

LPS Group is expected to start construction later this year.

Sherpa is already well advanced on construction of its debut Flourish project, Flourish Amargo, located just around the corner from Soleira. Meanwhile, Flourish Oasis, positioned opposite Amargo, recently commenced construction and has nearly sold out its collection of 47 apartments.

Are mortgage holders set to get a reprieve from the RBA in 2026?

Big Four bank NAB believes so. They are now expecting the next move from the RBA to be a cut, rather than a hike, which they had pencilled in for August. They are unsure of the timing of the cut however, they note in their latest&nbsp;NAB Economics RBA Watch.

NAB Chief Economist, Dr Sally Auld, said recent data suggests the economy has lost momentum and the outlook for rates has shifted, noting that the broader economic backdrop has changed since earlier in the year.

“The next move in the cash rate is likely to be down, but the timing is uncertain," Dr Auld said.

"In February, growth was above trend, the economy was operating above capacity and there was uncertainty over the restrictiveness of rates. None of these conditions exist today,” she outlined.

Dr Auld said recent data pointed to softer momentum across the economy while acknowledging that at the same time, uncertainty remains a key feature of the outlook.

“Both Q1 GDP data and the NAB business survey suggest momentum in the economy has slowed, meaning that growth has likely peaked for the cycle. That said, we are cognisant there is still considerable uncertainty around the outlook, both with respect to activity and inflation.”

Dr Auld said inflation risks and labour market outcomes would be important to watch.

“On the prices side, we are still forecasting above target core inflation through to mid-2027. Margins will compress and weaker labour market outcomes are a risk.”

She said tighter financial conditions are expected to weigh on housing and activity.

“Tighter financial conditions will be reflected in a slowing in house price growth and housing credit growth. In summary, we have greater conviction that the next move in rates is down, but less conviction on the timing.”

Mortgage relief? NAB forecasts RBA rate cut, not hike, after softer economic conditions

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.”

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.
