If you own an investment property in Brisbane, you are likely aware that the property investment landscape is undergoing significant changes. The 2026 Federal Budget, unveiled on 12 May, has introduced important modifications that will reshape your approach to property investments in the near future.
To summarise, purchasing an established investment property after this date will result in losing negative gearing benefits starting from 1 July 2027. Conversely, if you choose to construct new properties, you will retain this advantage. This change stems from a government initiative aimed at boosting the supply of new housing. The government is actively promoting new builds, which come with tax benefits, while established properties will lose these advantages.
For investors who have historically focused on acquiring and holding established properties, this marks a major shift in strategy. If you are currently evaluating your next investment move, prioritising the construction of new properties is now more essential than ever.
Explore the Major Changes in Property Investment Regulations
Before 12 May 2026, the negative gearing mechanism applied to both new and established properties equally. If your rental income fell short of covering your expenses — including mortgage interest, rates, insurance, and maintenance costs — you could offset these losses against your total income, effectively lowering your tax liability. Many investors were familiar with this system, which greatly influenced their investment strategies.
Starting from 1 July 2027, this offset will be exclusive to new builds. If you buy an established property after 12 May 2026, your rental losses will only be able to offset other property income. This means you will no longer be able to reduce your taxable income from salary or other investments. The appealing tax benefits that made negatively geared properties attractive to higher-income earners will be eliminated for existing properties.
New builds will retain the full benefits of negative gearing. Investors in new builds can choose between a 50 percent capital gains tax (CGT) discount or opting for cost base indexation upon sale, depending on what best suits their financial circumstances.
For high-income individuals considering their next investment, the financial implications of new builds versus established properties have changed dramatically. If you have not yet discussed these changes with your accountant, make it a priority to initiate that conversation.
Clarifying What Constitutes a New Build
At this point, the specifics are crucial.
The government’s criteria for an eligible new build are clear: the property must contribute to increasing the housing supply. This includes:
- A dwelling constructed on vacant land qualifies. If it is a new construction on an empty block, it is eligible.
- A duplex or dual occupancy resulting from a knockdown rebuild qualifies, provided you are replacing one dwelling with multiple units. For example, demolishing a single house and building a duplex increases supply and meets the criteria.
- However, a knockdown rebuild that replaces one house with another single house does not qualify. 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.
- A granny flat added to an existing property does NOT qualify for negative gearing on the granny flat portion.
The implications for Brisbane investors are evident: if you possess a substantial block and are contemplating your next steps, choosing to build a duplex or dual occupancy instead of a single dwelling is no longer just a design decision. It now determines whether your build qualifies as a new build under the current regulations.
Why High-Value Investments Over $1 Million Are Now Particularly Appealing
The individuals most affected by these changes are high-income earners — those who previously benefitted from negative gearing by offsetting losses against income taxed at 47 cents on the dollar.
These are precisely the investors that Iconic seeks to attract for construction.
A duplex or dual occupancy project with Iconic typically commences at $1 million for the construction alone. This figure does not represent a standard project home price; it reflects a custom, architect-designed build featuring two fully independent dwellings tailored for the block and built to last.
At this price point, the tax implications are significant. The rental income generated from two dwellings is considerable, making the negative gearing advantage on a high-value build especially noteworthy. The CGT position for a quality new build held over the medium to long term, particularly 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 unique circumstances. The overall 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 surprises investors.
The time from your initial discussion with a builder to receiving the keys for a duplex or dual occupancy build typically spans at least 18 months. The design and approval process can take between 4 to 6 months, followed by construction, which generally lasts 10 to 14 months.
The new regulations will become effective on 1 July 2027, which is just 13 months away.
Investors aiming to have a completed, tenanted new build before the regulations change have likely already missed this window. The key perspective is this: those who want to be strategically positioned under the new rules — with a qualifying new build underway or contracted — must make decisions now, rather than delaying for six months.
You need to identify or already own the land. Your financing must be arranged. A feasibility assessment of what can be built is necessary. Each of these steps requires time and must proceed in a sequential manner.
If you are serious about this opportunity, it is time to discuss your plans. This is not about creating urgency; it’s about adhering to concrete timelines.
Identifying Optimal Investment Blocks in Brisbane
Not every block is suitable for a duplex or dual occupancy build, and some locations are not conducive to investments of this scale. Here are key factors to consider.
Size and zoning: Under the Brisbane City Plan 2014, a minimum of 600 square metres is generally required for dual occupancy. The Redlands have similar requirements under the Redland City Plan. Zoning is also critical — some zones permit dual occupancy, while others do not. Conducting a feasibility assessment before acquiring land is essential.
Slope: A flat or gently sloping block is significantly more economical to build on compared to 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 — demonstrate strong and consistent rental demand for well-designed dual occupancy and duplex properties. Investors must keep in mind that council rates in the Redlands are noticeably higher than those in the Brisbane City Council. This disparity can accumulate on a dual occupancy or duplex and must be included in your financial calculations prior to 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 are currently hotspots. 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 purchasing a block with an existing house, be sure to account for 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, whereas a one-for-one replacement does not.

Navigating the Construction Process for Investment Properties
The process of building a duplex or dual occupancy for investment purposes is not significantly different from constructing a custom home; however, several key considerations must be taken into account.
Financing differs. 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 receive 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 increased long-term capital value. Investing in design choices that create a quality standalone dwelling is worthwhile.
Fixed-price contracts are essential. For an investment build, a fixed-price contract is vital. It is what your lender will demand and what safeguards your budget. Variable cost contracts on investment properties can lead to budget overruns during critical moments. Ensure your builder provides a legitimate 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 surprises when presented to a builder. A builder with an in-house design team ensures that cost considerations remain central to every design decision, preserving the integrity of your investment model.

Understanding the Distinctions Between Dual Occupancy and Duplex for Investment Success
Both options can achieve success, but understanding the differences is crucial:
A duplex consists of two dwellings connected side by side or stacked, sharing a common wall. Generally, this is more efficient to build on a standard block. Subdivision into two separate titles is possible after construction.
A dual occupancy features two dwellings on one title, either attached or detached. A typical layout includes 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 allow.
For investors, key considerations include: what does your block permit, 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 essential discussions to have with your builder and accountant before finalising designs.

Do You Have Questions About Investment Properties?
Frequently Asked Questions
Does a knockdown rebuild qualify for negative gearing under the new regulations?
Only if it increases the number of dwellings. For instance, demolishing a single house and constructing a duplex qualifies, whereas replacing one house with another single house does not. The government’s policy is focused on 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 prior to the first sale. If you are buying a completed new build from a developer who constructed it as a development project, ensure you closely examine the occupancy history.
Must I have the build completed before 1 July 2027 to qualify?
No. The key factor is that the property must be a new build — not its completion date. What is important 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 influence this. Some zones do not permit dual occupancy regardless of block size. Conducting 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. The design and approval stages typically take 4 to 6 months, followed by construction lasting 10 to 14 months. Complications arising 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 assess whether the tax implications make sense for your specific income and investment structure. Your builder can evaluate whether your block is suitable and if your budget is realistic for a qualifying new build. Each conversation is brief but informative.
