I’m often asked where “effective lives” come from, and the short answer is the Commissioner of Taxation. The long answer is a lot more complicated than that.
For those uninitiated in how depreciation rates are calculated for plant and equipment assets, the effective life is important because it drives the depreciation rate. Take, for example, the addition of carpet to a rental property. As at the time of writing, the depreciation rate under the diminishing method is 20%. This is calculated by dividing 200 by an effective life of 10. The commissioner is responsible for giving us the effective life of carpet at 10 years.
Effective lives are determined by the commissioner through estimating the period if can be used by any entity for a taxable purpose (within an investment property), assuming it is:
<ul>
<li> subject to wear and tear at a reasonable rate; and</li>
<li>maintained in good order and condition. </li>
</ul>
The commissioner determines the effective life based on historical information and future expectations. He or she specifically considers things such as those mentioned below.
1. The physical life of the asset
This relates to the period a depreciating asset can be used by an entity for the relevant purpose. The case may be put that as long as the asset physically exists and is not physically exhausted, then it is able to be used. In this case we’re looking at the outer limit of an assets life through historical evidence.
2. Engineering and manufacturers specifications
The estimate of an effective life will not always remain the same. Changes in technology and the quality of manufacture will result in an increase or decline in the usable life of an asset. Manufactures specs are a good guide to how long something will last. Warranty periods can also give an indication of the evolution of an assets effective life over time. If ceiling fans that have always had a five-year warranty but newer models are coming out with 10 years, there’s a case to the argument for an increase in the effective life.
 3. The way the asset is used by an industry
We touched previously on the past experience of users in the first point, but it’s interesting to note that not all industries use their assets in the same way. A perfect example exists in the different effective life of carpets. For example:
Residential property = 10 years
Commercial offices = 8 years
Accommodation providers = 7 years
Restaurants, pubs and the like = 5 years
Perhaps the most entertaining example is the difference between the effective life of furniture in a pub depending on whether it exists in a dining area (eight years) or a drinking area (a mere five years!) Clearly the furniture gets a much harder time where booze is involved!
In all seriousness, this is where property owners need to engage an experienced tax depreciation quantity surveyor, as knowing the difference between these effective lives can result in significant increases in tax deductions.
4. Levels of repairs and industry standards
Some plant and equipment items could in theory be repaired on an ongoing basis in order that they continue operating indefinitely. However, the legislation states that an asset only need be maintained in reasonably good order and condition. The term reasonably considers that it is not always reasonable to continue spending money on an asset where it would make more economic sense to dispose of it a purchase a new one.
5. Obsolescence, abandonment and scrapping
Plant and equipment assets can become obsolete either through technological or commercial reasons. For example, something may become commercially obsolete because the asset produces goods that are no longer required or current. Technological obsolescence is something we’re all familiar with. Anyone with a mobile phone understands that over time tools become available that perform the same tasks faster, more efficiently, and with more relevance to the greater marketplace. However. an asset’s life does not necessarily end because something newer has come along. Obsolescence is only considered when it prevents the continued use of the asset for the purpose it was designed.
Quantity surveyors are able to “scrap” assets that have reached the point of obsolescence, or the end of their productive life. Say for example you have owned a property for some time and are undertaking renovations. Assets like old blinds, carpets, cooktops and the like will have a residual value that can be written off, as the assets are being thrown away and replaced. Scrapping is a practice that I will elaborate upon further in another article.
6. Market values, economics and financial analysis
Lease periods can be a good indicator of the effective life of an asset as it is unlikely that an asset would be leased for a period longer than it is useful. In the same way, an effective life should be no shorter than the period it can be leased for. If a company leases a crane for 10 years, it clearly believes (and have historical evidence/manufacturers specifications) that demonstrate that it will last the whole of that time. This can be expanded into a financial analysis. If, for example, a large manufacturing plant and equipment item costs a certain amount to purchase, there must be an expectation that it will serve its purpose preparing or producing a certain quantity of products for a certain number of years.
In evaluating market values for the determination of effective lives, it can be seen that depreciating assets with a market value will decline in value over time. For example, a brand-new lawn mower might be $400 today, however in four years’ time its value will be closer to $200.
In analysing the decline in value over time, you can get a sense of the time it takes for the majority of its value to depreciate away.
In conclusion, there is a significant amount of analysis and empirical evidence that can be used to estimate the effective life of an asset, and I hope that this explanation of some of the tools at the commissioner’s disposal sheds some light on where an effective life comes from.
 It’s also important to remember that property owners are able to determine their own effective lives based on these factors, however it is best to contact a quantity surveyor or similarly qualified expert before doing so.
For more information you can search for the relevant taxation legislation on effective lives, such as TR 2011/2 (as at the time of writing), where you can find more information about the determination of effective lives. This legislation is normally updated for the beginning of each financial year.

How to determine the effective life of a depreciating asset in your property

A luxury beachfront apartment at Rainbow Bay has more than doubled in value since it sold off the plan six years ago, setting a new local apartment record in the process.

The three-bedroom apartment in the Flow development on Petrie Street, the first of four new projects locally by Paul Gedoun's S&amp;S Projects, has sold for $7.4 million, after originally selling for $3.27 million when the project launched in 2020.

The seventh-floor apartment, comprising 187 sqm of internal living space and a 54 sqm balcony overlooking Froggies Beach and Snapper Rocks, was purchased by a local family.

The transaction was negotiated by Pezet Matheson director Kerry Pezet and equates to more than $30,000 per sqm.

Pezet said the sale reflected the limited opportunities to buy into the boutique beachfront development.

"The sale highlights the rarity of opportunities within the boutique beachfront development, where residences seldom become available," Pezet said.

"Flow is one of the Gold Coast's most tightly held buildings. Buyers from our database move quickly when residences become available, and achieving an off-market sale at $7.4 million demonstrates the depth of demand for property of this calibre."

<img alt="Flow" data-entity-type="file" data-entity-uuid="c585b206-2130-4eee-a50c-3f27c51a7c70" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-07-06%20at%208.33.25%E2%80%AFPM.png?VersionId=m3pHRDV62Y3fvN.XQuQHq.52ilTWpRLf" />

Flow was the first of four luxury apartment developments delivered by Paul Gedoun's S&amp;S Projects at Rainbow Bay and was completed in 2023.

Positioned on the beachfront overlooking Snapper Rocks, the residence includes three bedrooms, three bathrooms, a powder room and views stretching north along the coastline towards Surfers Paradise.

Pezet Matheson Residential principal Mitchell Lambert said buyers continued to prioritise quality beachfront apartments in tightly held locations.

"Flow Residences offers a rare combination of elevated beachfront positioning, architectural excellence, comprehensive resident amenity and premium finishes, which is exactly what discerning purchasers are seeking," Lambert said.

"The transaction further reinforces Rainbow Bay's reputation as one of Australia's premier coastal lifestyle destinations, where limited supply and growing demand continue to support strong market performance."

Pezet Matheson originally marketed and sold out Flow off the plan, making the latest transaction a return to one of the project's original buyers.

Paul Gedoun is selling his third project, <a href="https://www.apartments.com.au/new-apartments/radia-rainbow-bay-271-boundary-street-coolangatta-qld-4225">Radia Rainbow Bay</a>, after recently completing, and selling out, <a href="https://www.apartments.com.au/buildings/esprit-217-227-boundary-street-coolangatta-qld-4225">Esprit</a>.

The long-planned transformation of Brisbane's historic Shafston Estate has taken another major step, with Capella Hotel Group announced as the luxury hospitality partner behind what will become Brisbane's first branded residences.

The project, to be known as Capella Residences Brisbane, is being delivered by Verso Projects at the landmark Kangaroo Point riverfront estate, with completion targeted for 2029.

The announcement follows a series of planning changes to the project over recent years. The site was originally approved in 2023 for a 15-level, 37-apartment development designed by Rothelowman for Burgundy Group before Verso Projects took over the 10,070 sqm riverfront holding and lodged revised plans with Kerry Hill Architects to increase the development to a 25-level tower with 51 apartments.

The latest announcement confirms Capella Hotel Group will bring its branded residential offering to the project, marking just the second Capella Residences development globally after Seoul, and the group's first branded residential project in Australia.

The <a href="https://www.apartments.com.au/new-apartments/23-castlebar-street-kangaroo-point-qld-4169">Castlebar Street development</a> will centre around the restoration of the heritage-listed Shafston House, one of Brisbane's oldest residences, originally constructed in 1851 by Reverend Robert Creyke as a single-storey cottage known as Ravenscott.

<img alt="Capella" data-entity-type="file" data-entity-uuid="2b9f4ce5-638f-4d6b-8082-3ca7e4b75fca" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-07-09%20at%207.20.41%E2%80%AFAM.png?VersionId=f7aeqsW_DzOJI4FymWb3lD8NptSfsP7q" />

Capella said the project aligns with its focus on heritage-led developments, with the Brisbane estate combining the restored historic residence with a new luxury apartment tower and hospitality-inspired resident amenities.

Residents will have access to the Capella Living Room, a concierge-led communal space inspired by the group's luxury hotels, alongside landscaped gardens, six swimming pools, wellness and recreation facilities.

The broader estate will also include two riverfront homes, a six-berth private marina, porte cochère arrival experience, secure basement parking and a new section of public riverwalk along the Brisbane River frontage.

The heritage Postal Depot Building will also be retained and repurposed as a guest house, in line with the revised development plans.

The project represents another evolution for the site, which Kerry Hill Architects previously described as a rare opportunity to restore one of Brisbane's most significant heritage estates while creating a new benchmark for apartment living.

"The Shafston Estate provides a once-in-a-generation opportunity to restore one of Brisbane's finest heritage precincts and to reinstate residential use as a unique site perched on the edge of Kangaroo Point," Kerry Hill Architects said in its Urban Context Report accompanying the planning submission.

"The project will celebrate excellence in sub-tropical residential design, setting a new benchmark for vertical living in Brisbane."

Verso Projects, which now has an $8.5 billion development pipeline spanning more than 6,000 dwellings across apartments, townhouses, retail and commercial projects, said the partnership with Capella would elevate the development beyond a traditional residential project.

"We feel honoured to be restoring Shafston Estate to its former glory, elevating it to new heights of luxury and excellence underpinned by Capella's distinctive service ethos and design philosophy, and making it a standout landmark in Brisbane," Verso Projects CEO Steve Laffey said.

"By partnering with Capella, globally recognised for its refined approach to luxury hospitality and deep respect for cultural and historical context, we will elevate this project beyond a residential offering into a world-class destination."

Capella Hotel Group President Roland Fasel said Brisbane's emergence as a global city made it the right location for the company's Australian residential debut.

"Brisbane is a city on the cusp of something remarkable, and Capella Residences is our commitment to being part of that story," Fasel said.

"The Capella residential experience is more than luxury. It is about a sense of belonging to a place with deep meaning."

Private appointments have now opened for the project, with a display suite expected to open in late 2026 ahead of the planned 2029 completion.

Capella to launch Brisbane's first branded residences at Shafston House, Kangaroo Point

Lewis Land's latest apartment release within its <a href="https://www.apartments.com.au/new-apartments/harbour-shores-biggera-waters-564-oxley-drive-biggera-waters-qld-4216">Harbour Shores</a> masterplan is targeting one of the Gold Coast's fastest-growing buyer groups, with almost a third of apartments at Solis priced below $1 million.

The seven-storey building at Biggera Waters will comprise 91 apartments, including 24 one-bedroom residences starting from $778,000, a price point Lewis Land says is aimed squarely at first home buyers struggling to enter the Gold Coast market.

<img alt="Harbour Shires" data-entity-type="file" data-entity-uuid="e7486e37-22f6-4c92-b212-9b0622070b8f" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-07-08%20at%209.09.34%E2%80%AFAM.png?VersionId=W8MJwJUCf6HkIyl_EVSksnd.QI6MZryY" />

<a href="https://www.apartments.com.au/developers/lewis-land-group">Lewis Land</a> Head of Development Michael Long said the developer deliberately allocated a significant proportion of the project to more affordable apartment types.

"First home buyers have been priced out of many parts of the Gold Coast, and we saw a clear opportunity to address this and play our part in a longer-term housing solution," Long said.

"That's why 24 of the 91 apartments being delivered at Solis have been designed and priced for the city's next generation of homeowners, quality one-bedroom apartments, half of which include an additional multipurpose room to maximise space and flexibility.

"This approach places 30 per cent of apartments in Solis under $1 million, and with close proximity to Harbour Town's future light rail extension connecting residents to the city's major employment and knowledge hubs, it's a win for buyers looking to secure their first property."

<img alt="Sores" data-entity-type="file" data-entity-uuid="550526d3-73ba-4710-9739-c5f4294a30ef" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/Screenshot%202026-07-08%20at%209.09.29%E2%80%AFAM.png?VersionId=cQQdXHt9wS0UXwZEm5Py5bH_3kAmzyhu" />

Designed by BDA Architecture, Solis will deliver a mix of one, two and three-bedroom apartments, with residences ranging up to 232 sqm. Apartments feature generous balconies and contemporary finishes, while residents will have access to Harbour Shores' lagoon pool, clubhouse, tennis court, gym, yoga studio and sauna.

The focus on first home buyers resonated with purchaser Holly Humphreys, who said she and her boyfriend spent more than a year searching for their first property before shifting their attention from houses to apartments.

"We fell in love with the first house we bid on and got our hopes up, but after repeated knockbacks we learned not to get too attached," Humphreys said.

"We offered at the high end of price guides, but sales kept going even higher. That's where we really struggled and we needed to re-evaluate our budget and our expectations. Standalone houses were off the table, and we pivoted to apartments and townhouses."

Humphreys said it was encouraging to see developers recognising the growing demand from first home buyers.

"There's a growing number of young buyers looking to enter the market earlier because they understand that getting in now can make a real difference as prices continue to rise," she said.

"It's fantastic to see a developer recognise this and then actively take measures to deliver an apartment with us in mind."

Solis is the first development planned within the second stage of the Harbour Shores masterplan, with early works expected to commence in September 2026.

Lewis Land targets first home buyers at latest Harbour Shores release, Solis

Luxury apartment developer Abadeen has recorded $19.25 million in apartment sales across two of its Lower North Shore developments in the lead-up to the end of the financial year, headlined by the sale of a $6.75 million penthouse at <a href="https://www.apartments.com.au/buildings/koyo-crows-nest-5-rodborough-avenue-crows-nest-nsw-2065">KOYO in Crows Nest.</a>

The transactions also included the sale of a newly completed three-bedroom apartment at <a href="https://www.apartments.com.au/buildings/park-residences-cremorne-2-sutherland-street-cremorne-nsw-2090">Park Residences in Cremorne</a> for $6.35 million, with the residence selling shortly after the project's first public inspections following completion.

The sales come as completed, owner-occupier-focused apartments continue to attract strong demand across Sydney's Lower North Shore, particularly from buyers looking for certainty and immediate occupancy.

The penthouse at KOYO spans 491 sqm across a single level and was designed by architect Koichi Takada. The development is one of Abadeen's flagship boutique projects in Crows Nest.

[smartcode_project:default project_id=108800 project_image_fid=370093]

Abadeen Executive Chairman and Founder Justin Brown said buyer activity lifted noticeably in the lead-up to the end of the financial year.

"We saw a clear increase in enquiry levels, inspection numbers and buyer engagement across our completed projects leading into the end of the financial year," Brown said.

"Buyers have become far more decisive over the past six months. The combination of improving confidence, limited supply and the ability to physically inspect completed residences is creating strong competition for premium apartments in the best locations."

Brown says the&nbsp;response to Park Residences following completion has been particularly strong.

"Buyers want certainty and are responding positively to the opportunity to walk through a finished product, inspect the quality firsthand and move in immediately," Brown suggested.

"Projects such as Park Residences and KOYO demonstrate that when the product is exceptional and the location is irreplaceable, buyers are prepared to act quickly."

[smartcode_project:default project_id=114246 project_image_fid=370116]

Abadeen CEO Joe Tack said quality continued to differentiate projects in the current market.

"Today's buyers are incredibly discerning," Tack said.

"They are seeking larger floorplans, premium finishes, walkability, lifestyle amenity and confidence in the developer delivering the project. Well-designed boutique developments continue to outperform because they offer something genuinely difficult to replace.

"The enquiry we are seeing across our completed and recently completed Lower North Shore portfolio is very encouraging, and we expect this momentum to continue into spring."

The sales follow increased enquiry across Abadeen's Lower North Shore portfolio which also includes <a href="https://www.apartments.com.au/buildings/northcote-collective-naremburn-2-northcote-street-naremburn-nsw-2065">Northcote Collective in Naremburn</a> which also completed recently.

The City of Sydney has approved plans for <a href="https://www.apartments.com.au/developers/billbergia">Billbergia Group</a> and Metrics Credit Partners’ $3.5 billion Castlereagh Place project in the heart of the Sydney CBD

The towers will be among the tallest in <a href="https://www.apartments.com.au/developments/sydney-nsw-2000">Sydney</a>'s CBD, with more floors than any other residential tower in the city.&nbsp;

The 6,000 sqm site was acquired by the joint venture partners in 2024. It is the largest amalgamated land parcel in the Sydney CBD and comprises eight individual sites fronting Castlereagh, Pitt and Liverpool Streets.&nbsp;

<a href="https://www.apartments.com.au/new-apartments/castlereagh-place-sydney-324-348-pitt-street-sydney-nsw-2000">Castlereagh Place</a> will transform an underutilised city block into a landmark mixed-use destination, anchored by two 82-storey towers comprising 607 luxury residences above an 8-level podium housing a 209-room luxury hotel. A 1,000 square metre civic park on ground level features a curated mix of food, beverage and retail.

The plans have been refined over the past year to rebalance the residential and hotel offering, and reconfigure the retail footprint to create a stronger, more dynamic dining experience.

A three-level flagship building on the prominent corner of Pitt and Liverpool Streets will be the gateway to the Castlereagh Place lifestyle precinct. Set to become a Sydney icon, the building is capable of housing multiple hospitality venues.

“Castlereagh Place is designed to be the City's next great urban oasis - an energetic mixed-use precinct that pulses with life, day and night,"&nbsp;said Joseph Kinsella, Group Director of Billbergia.

"It will bring the vibrancy of places like Barangaroo and Darling Quarter into a more accessible, central destination at the very heart of Sydney."

Kinsella said the project will build on&nbsp;Sydney’s growing laneway culture with the City’s largest network of new activated lanes - an expanded, next-generation take on precincts like Angel Place, Palings Lane and Ash Street in Wynyard.

[smartcode_project:default project_id=134477 project_image_fid=374401]

Castlereagh Place has been designed by architects <a href="https://www.apartments.com.au/architects/fjc-studio">fjcstudio</a> in collaboration with Trias Studio, Aileen Sage and Polly Harbison Design, joint winners of an international design competition in 2018.&nbsp;

Signature design elements from the original scheme remain unchanged, while the public domain has been significantly enhanced, delivering 60 per cent more open-to-sky space.

Pedestrian access will also be enhanced through new laneways linking Pitt, Liverpool and Castlereagh Streets, drawing people into a new civic park with outdoor seating, landscaping and integrated public art.

With activated laneways supported by strong hospitality offerings, Castlereagh Place is tipped to become a vibrant new dining destination in the heart of Sydney’s CBD.

It marks the largest undertaking to date for the Billbergia and Metrics Credit Partners partnership. Together they are developing other underutilised Sydney sites into mixed-use precincts, including the $2.2 billion Concord Central and the $1.3 billion Chatswood Grand Residences.

Metrics Managing Partner and Group CEO Andrew Lockhart said Castlereagh Place is a landmark project that will redefine Sydney’s skyline.

"As the tallest residential high-rise development, the revitalised site will offer panoramic views across the CBD and surrounds. We are excited to partner with Billbergia to reinvigorate an underutilised site and create a sophisticated and contemporary mixed-use offering situated in the heart of Sydney.”

Total apartments within the towers have increased to 607 dwellings, with a focus on larger floorplans. Aligned to growing market demand, Castlereagh Place now comprises 299 three-plus-bedroom apartments, 198 two-bedroom units and 110 one-bedroom configurations.

[smartcode_project:default project_id=134477 project_image_fid=374402]

Resident amenities will include an exclusive residents club containing a gym, rooftop pool, dining rooms, co-working spaces, library, golf simulator, games room, cinema room, and access to an exclusive concierge service. There will be around 500 basement car spaces below the towers.

The development will also include a state-of-the-art wellness centre, set to feature a bathhouse with magnesium pools, hot/cold plunge pools and premium amenities.

&nbsp;

According to fjcstudio, the towers will feature distinctive yet elegant architectural design reflecting Sydney’s geometry and urban character, with a network of through-site links and intimate public spaces activating the streetscape.

"Castlereagh Place is a city-making project of significant scale and ambition," said Richard Francis-Jones, Design Director at fjcstudio.

"It will create a rich urban complex of public open spaces, landscaped gardens, and vibrant laneways. Defining these new public spaces and the important streetscape of Castlereagh Street is a sequence of fine-grained, diverse retail and hotel architecture designed in collaboration with Aileen Sage, Polly Harbison Design and Trias.

“Rising above the tree-lined, human-scale streetscape are two slender residential towers that will transform the city skyline and look towards the Harbour, Hyde Park, and the Royal Botanic Garden.”

Demolition and early construction works have commenced onsite at Castlereagh Place.
