As an investment property owner in Brisbane, you may have noticed the significant transformations within the property investment landscape. The 2026 Federal Budget, unveiled on 12 May, has brought forth considerable changes that will alter your approach to property investments moving forward.
In summary, acquiring an established investment property after this date means you will lose the negative gearing benefits starting from 1 July 2027. On the other hand, if you decide to build new properties, you will maintain these advantages. This adjustment is not just a loophole; it results from government policy aimed at enhancing the supply of new housing. The government actively encourages new builds, which come with tax benefits, while established properties will forfeit these incentives.
For investors who have typically concentrated on buying and holding established properties, this represents a significant shift in strategy. If you are currently pondering your next investment decision, the focus on constructing new properties has never been more critical.
Understand the Key Changes in Property Investment Regulations
Prior to 12 May 2026, the mechanism of negative gearing applied equally to both new and established properties. If your rental income did not cover your expenses — including mortgage interest, rates, insurance, and maintenance costs — you could offset those losses against your total income, thereby reducing your tax liability. Most investors understood this mechanism, which significantly affected their investment strategies.
Starting from 1 July 2027, this offset will be limited to new builds. If you purchase an established property after 12 May 2026, your rental losses can only be offset against other property income. This means you will no longer be able to diminish your taxable income from salary or other investments. The attractive tax advantages that made negatively geared properties appealing to higher-income earners will no longer apply to existing stock.
On the contrary, new builds will continue to offer the full benefits of negative gearing. Investors in new constructions can opt for a 50 percent capital gains tax (CGT) discount or choose cost base indexation upon sale, depending on what aligns best with their financial situations.
For high-income individuals contemplating their next investment, the post-tax financial implications of new builds versus established properties have shifted dramatically. If you have not yet consulted with your accountant about these changes, make this a priority.
Defining What Qualifies as a New Build
The specifics of the criteria are critically important.
The government’s requirements for an eligible new build are precise: the property must contribute to an increase in the housing supply. This includes:
- A dwelling built on vacant land is eligible. A new construction on an empty block qualifies.
- A duplex or dual occupancy resulting from a knockdown rebuild qualifies, as long as 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.
- 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 clear: if you possess a sizeable block and are contemplating your next steps, opting for a duplex or dual occupancy instead of a single dwelling is now more than just a design choice. It now determines whether your build qualifies as a new build under the current regulations.
Why High-Value Investments Over $1 Million Are Particularly Attractive Now
The changes will predominantly affect high-income earners — those who previously benefited 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 is not a typical project home price; it represents a custom, architect-designed build featuring two fully independent dwellings that are tailored for the block and built for longevity.
At this price point, the tax implications become significant. The rental income generated from two dwellings is substantial, 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, particularly in a Brisbane market facing genuine supply constraints, is promising.
This is not financial advice. Always consult your accountant for tailored guidance based on your individual circumstances. The case for a high-quality duplex or dual occupancy build in Brisbane has rarely been more compelling.
Recognising the Timeline and Its Critical Importance
This aspect often surprises investors.
The duration from your initial discussion with a builder to receiving the keys for a duplex or dual occupancy build is typically 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 only 13 months away.
Investors hoping to have a completed, tenanted new build before the regulations change may have already missed this opportunity. The right perspective is this: those who want to be strategically positioned under the new rules — with a qualifying new build either underway or contracted — must make decisions now rather than waiting six months.
You need to identify or already own the land. Your financing needs to be arranged. A feasibility assessment of what can be built must be conducted. Each of these steps requires time and must be completed 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 genuine timelines.
Identifying Suitable Investment Blocks in Brisbane
Not every block is appropriate 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 vital — some zones permit dual occupancy, while others do not. Conducting a feasibility assessment before purchasing land is essential.
Slope: A flat or gently sloping block is considerably cheaper 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 be aware 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 targeting Brisbane City Council areas, medium-density suburbs like Wynnum, Manly, Carindale, Bulimba, Cannon Hill, Camp Hill, Morningside, and Coorparoo are currently where opportunities abound. These locations offer strong rental demand, good access to amenities, and zoning that generally 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, while a one-for-one replacement does not.

Optimising 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, there are several key considerations to keep in mind.
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 knowledgeable about 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 perceive. Thoughtful design leads to better tenants, lower vacancy rates, and increased long-term capital value. Investing in design choices that make a property feel like a quality standalone dwelling is worthwhile.
Fixed-price contracts are essential. For an investment build, a fixed-price contract is crucial. 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 moments. 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 particularly 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 Distinction Between Dual Occupancy and Duplex for Investment Success
Both options can be successful, but recognising the differences is essential:
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 vital discussions to have with your builder and accountant before finalising designs.

Do You Have a Question?
Addressing Common Questions
Does a knockdown rebuild qualify for negative gearing under the new regulations?
Only if it increases the number of dwellings. For example, 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, as long as the property has not been occupied for more than 12 months before the first sale. If you are purchasing a completed new build from a developer who constructed it as a development project, ensure you review the occupancy history carefully.
Must I have the build completed before 1 July 2027 to qualify?
No. The critical 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 play. Some zones do not permit dual occupancy regardless of block size. A feasibility assessment of your specific block prior to purchase is crucial.
How long does it take to build a duplex or dual occupancy?
From the initial consultation to handover, you should budget for a minimum of 18 months. Design and approvals usually take 4 to 6 months, followed by construction which 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 occur now. Your accountant can assess whether the tax implications make sense for your particular 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.
