As a property investor in Brisbane, you may have observed considerable changes in the property investment environment. The 2026 Federal Budget, revealed on 12 May, has introduced significant modifications that will influence your future property investment strategies.
To summarise, if you acquire an established investment property after this date, you will forfeit the negative gearing benefits starting from 1 July 2027. Conversely, opting to build new properties allows you to retain these advantages. This shift is a deliberate government policy aimed at boosting the supply of new housing. The government is actively promoting new developments, which come with tax benefits, while established properties will lose these incentives.
For investors who have primarily focused on purchasing and holding established properties, this marks a pivotal change in investment strategy. If you are contemplating your next investment move, prioritising the construction of new properties is now more crucial than ever.
Discover the Essential Changes in Property Investment Regulations
Before 12 May 2026, the concept of negative gearing applied uniformly to both new and established properties. If your rental income fell short of covering expenses—such as mortgage interest, rates, insurance, and maintenance costs—you could offset those losses against your total income, effectively lowering your tax liability. This mechanism was well understood by most investors and significantly influenced their investment strategies.
Beginning on 1 July 2027, this offset will only apply to new builds. If you acquire an established property after 12 May 2026, your rental losses can only be offset against other property income. This change means you can no longer reduce your taxable income from salary or other investments. The appealing tax benefits that attracted higher-income earners to negatively geared properties will no longer be available for existing assets.
In contrast, new builds will retain the full advantages of negative gearing. Investors in new constructions will have the option of a 50 percent capital gains tax (CGT) discount or might choose cost base indexation upon sale, depending on their financial circumstances.
For high-income earners considering their next investment, the post-tax financial consequences of new builds compared to established properties have changed significantly. If you haven’t spoken with your accountant about these developments yet, make it a priority.
Understanding What Constitutes a New Build
It is crucial to grasp the specifics of the criteria.
The government stipulates clear requirements for an eligible new build: the property must contribute to an increase in the housing supply. This includes:
- A dwelling constructed on vacant land is eligible. Any new construction on an empty block qualifies.
- A duplex or dual occupancy resulting from a knockdown rebuild qualifies, provided you replace one dwelling with more than one. For instance, demolishing a single house to build a duplex increases supply and meets the criteria.
- However, a knockdown rebuild that replaces one house with another single house does not qualify. The government documentation explicitly states that a one-for-one replacement of free-standing houses is NOT an eligible new build for negative gearing purposes.
- A newly constructed apartment purchased off the plan qualifies as a new build.
- An added granny flat to an existing property does NOT qualify for negative gearing on the granny flat portion.
The implications for Brisbane investors are evident: if you own a sizeable block and are contemplating your next steps, choosing to develop a duplex or dual occupancy instead of a single dwelling is now more than just a design decision. It now dictates whether your build qualifies as a new build under the current regulations.
Why High-Value Investments Over $1 Million Are Especially Attractive Now
The changes will primarily impact high-income earners—those who previously benefitted from negative gearing by offsetting losses against income taxed at 47 cents to the dollar.
These are the investors that Iconic specifically targets for construction.
A duplex or dual occupancy project with Iconic typically begins at $1 million for construction alone. This figure does not reflect a typical project home price; it represents a custom, architect-designed build comprising two fully independent dwellings tailored for the block and built for longevity.
At this price point, the tax implications become substantial. The rental income generated from two dwellings is significant, making the negative gearing advantage on a high-value build considerable. The CGT position for a quality new build held over the medium to long term, especially in a Brisbane market facing genuine supply constraints, is promising.
This is not financial advice. Always consult your accountant for personalised guidance based on your individual circumstances. The case for a high-quality duplex or dual occupancy build in Brisbane has rarely been more compelling.
Comprehending the Timeline and Its Vital Importance
This aspect often catches investors off guard.
The timeline from your initial discussion with a builder to receiving the keys for a duplex or dual occupancy build typically spans at least 18 months. Design and approvals can take between 4 to 6 months, followed by construction, which generally lasts 10 to 14 months.
The new regulations will take effect on 1 July 2027, which is merely 13 months away.
Investors aiming to complete and rent out a new build before the regulations change may have already missed this opportunity. The perspective to adopt is this: those seeking to be strategically positioned under the new rules—with a qualifying new build either underway or contracted—must make decisions now instead of waiting six months.
It is essential to identify or already own the land. Your financing must be arranged. A feasibility assessment of the potential build must be completed. Each of these steps requires time and must be executed in sequence.
If you are serious about this opportunity, now is the time to discuss your plans. This is not about creating urgency; it’s about adhering to legitimate timelines.
Finding Suitable Investment Blocks in Brisbane
Not every block is suitable for a duplex or dual occupancy build, and some areas are not conducive to investments of this scale. Here are key factors to consider.
Size and zoning: According to the Brisbane City Plan 2014, a minimum of 600 square metres is generally required for dual occupancy. The Redlands have similar stipulations under the Redland City Plan. Zoning is also critical—some zones allow for dual occupancy, while others do not. Conducting a feasibility assessment before purchasing land is essential.
Slope: A flat or gently sloping block is significantly cheaper to build on than a steep one. Site costs for a sloping block can add between $50,000 to $150,000 or more to your overall project. Ensure to factor these expenses into your land purchase budget.
Location and demand: Areas such as the Redlands—including Cleveland, Thornlands, Victoria Point, and Capalaba—exhibit strong and consistent rental demand for well-designed dual occupancy and duplex properties. Investors should note that council rates in the Redlands are notably higher than those in the Brisbane City Council. This difference can accumulate on a dual occupancy or duplex and must be included in your financial calculations before acquiring a block.
For investors focusing on Brisbane City Council areas, medium-density suburbs like Wynnum, Manly, Carindale, Bulimba, Cannon Hill, Camp Hill, Morningside, and Coorparoo currently present abundant opportunities. These locations offer strong rental demand, good access to amenities, and zoning that typically supports dual occupancy and duplex development.
Existing dwelling: If you are acquiring a block with an existing house, be sure to factor in demolition costs, which start around $25,000 depending on size and whether asbestos is present. A knockdown rebuild that transitions from one dwelling to two qualifies as a new build under the 2026 budget regulations, while a one-for-one replacement does not.

Streamlining the Build Process for Investment Properties
The process of constructing a duplex or dual occupancy for investment purposes is not dramatically different from building a custom home; however, several key considerations should be kept in mind.
Financing is distinct. A construction loan for an investment build releases funds in stages as construction progresses, rather than as a lump sum. Your broker should be well-versed in construction finance, and your borrowing structure must reflect the understanding that you won’t have rental income during the construction phase. Ensure your financing is organised before proceeding with any other steps—it influences every subsequent decision. For a detailed order of operations, refer to our Brisbane new build guide →
Design impacts yield. A duplex or dual occupancy designed solely to minimise construction costs may result in two dwellings that feel subpar, which tenants will notice. Thoughtful design leads to better tenants, lower vacancy rates, and greater long-term capital value. Investing in design choices that enhance a property’s appeal is worthwhile.
Fixed-price contracts are crucial. For an investment build, a fixed-price contract is essential. It is what your lender will require and what safeguards your budget. Variable cost contracts on investment properties can lead to budget overruns at critical times. Ensure your builder provides a genuine fixed-price contract and clarify what is included—and what is excluded—before signing.
Engage a builder with in-house design capabilities. This is especially important for investors compared to owner-occupiers. An independent architect or designer may create beautiful plans without considering costs, leading to unexpected surprises when presented to a builder. A builder with an in-house design team ensures that cost considerations remain central to every design decision, maintaining the integrity of your investment model.

Understanding the Differences Between Dual Occupancy and Duplex for Investment Success
Both options can be profitable, but understanding the distinctions is key:
A duplex consists of two dwellings connected side by side or stacked, sharing a common wall. This design is generally more efficient to build on a standard block. Subdivision into two separate titles is possible post-construction.
A dual occupancy features two dwellings on one title, either attached or detached. A typical layout features a house at the front and a second home at the rear. This arrangement can also be subdivided later if the block size and zoning permit.
For investors, key considerations include: what does your block allow, how does the local rental market respond, and what is the best strategy—maintaining both dwellings on one title or subdividing for potential separate sale or financing flexibility later? These are crucial discussions to have with your builder and accountant before finalising designs.

Do You Have Any Questions?
Addressing Frequently Asked Questions
Does a knockdown rebuild qualify for negative gearing under the new regulations?
Only if it results in an increase in the number of dwellings. For instance, demolishing a single house and building a duplex qualifies, whereas replacing one house with another single house does not. The government’s policy specifically targets new supply rather than replacement supply.
Can I negatively gear a new build duplex purchased from a developer?
Only the first buyer from the builder qualifies, provided the property has not been occupied for more than 12 months before the first sale. If you are acquiring a completed new build from a developer who constructed it as a development project, ensure you thoroughly review the occupancy history.
Must I have the build completed before 1 July 2027 to qualify?
No. The crucial factor is that the property is a new build—not its completion date. What matters is that you do not purchase an established property after 12 May 2026. A new build that is contracted and under construction after this date still qualifies.
What is the minimum block size for a duplex in Brisbane?
Typically, 600 square metres is required under the Brisbane City Plan 2014, but zoning and overlays also come into consideration. Some zones do not allow dual occupancy regardless of block size. A feasibility assessment of your specific block prior to purchase is essential.
How long does it take to build a duplex or dual occupancy?
From the initial consultation to handover, you should plan for a minimum of 18 months. Design and approvals typically take 4 to 6 months, followed by construction that lasts 10 to 14 months. Complications from site conditions or council assessments can extend this timeline.
Should I consult with my accountant or builder first?
Both discussions are valuable and should happen now. Your accountant can evaluate whether the tax implications align with your specific income and investment structure. Your builder can assess whether your block is suitable and if your budget is realistic for a qualifying new build. Each conversation is brief yet informative.
