Development Application Australia: What Property Developers Need to Know About DA Approval
You’ve found the site. The development concept looks promising. The feasibility shows a profit. Now you just get the architect to prepare some drawings and lodge a DA with the council.
That is where many developers underestimate the process.
A Development Application (DA) is not simply a collection of architectural drawings submitted for council approval. It is the formal planning process used to establish whether a particular development should be permitted on a particular piece of land, what impacts it may create, and what conditions should apply if it is approved.
For a property developer, that distinction is critical.
The development approval process can determine how many dwellings you can build, how much floor area you can achieve, where buildings can sit, how vehicles enter the site, how stormwater is managed and what additional infrastructure or environmental works may be required.
In other words:
The DA doesn’t just affect whether you can develop the site. It can determine whether the development remains financially viable.
There is another important point for developers operating across Australia: there is no single national DA system.
Planning legislation is largely administered at state and territory level. NSW, Queensland, Victoria, Western Australia and the other jurisdictions use different legislation, terminology, approval pathways and assessment processes.
So before asking:
“What do I need to do to lodge a DA?”
A developer should first ask:
“What approval pathway applies to this site, and what can realistically be approved?”
What Is a Development Application?
A Development Application is a formal request seeking consent or permission to undertake development on land.
Depending on the jurisdiction and proposed development, this can include:
Constructing houses, duplexes, townhouses or apartments;
Subdividing land;
Demolishing an existing building;
Undertaking alterations or additions;
Developing commercial or industrial premises;
Changing the approved use of a property; or
Carrying out other development requiring planning approval.
The assessment goes much further than deciding whether the proposed building looks acceptable.
Depending on the project, the planning authority may consider issues including traffic, access, privacy, overshadowing, noise, heritage, waste, environmental impacts and effects on neighbouring properties and the wider community.
This is why developers should stop thinking of a DA as:
Architectural Plans + Application Form + Council Fee
A more accurate description is:
Development Application = Planning Strategy + Design + Technical Evidence + Consultant Coordination + Statutory Assessment
The architectural drawings explain what you want to develop.
The rest of the application helps demonstrate why that development is appropriate for the site and how its impacts will be addressed.
Do You Actually Need a Development Application?
Before appointing an architect to prepare a complete DA package, establish which planning approval pathway applies.
Not every development requires a conventional Development Application.
NSW provides a good example.
Depending on the development and site, the planning system provides different approval pathways, including exempt development, complying development and development requiring consent through a DA.
Exempt Development
Certain low-impact development can proceed without formal planning approval where all relevant development standards are satisfied.
Depending on the circumstances, this can include minor works such as certain garden sheds, fences, decks and other small structures.
However, developers should be careful with the word “exempt.”
It does not mean that anything considered small can automatically be built without approval.
The development must satisfy the applicable standards, and site-specific constraints can affect eligibility.
Complying Development
NSW also has a streamlined approval pathway known as complying development.
Where a development and site satisfy strict predetermined requirements, a Complying Development Certificate (CDC) may provide a faster alternative to the conventional DA process.
A CDC combines planning and construction approval for eligible development and can be issued by council or a registered certifier.
Development Application
Where development requires consent and does not qualify for another pathway, a full Development Application may be necessary.
For property developers, the lesson is important:
Don’t decide to lodge a DA before determining whether a DA is actually the right approval pathway.
The approval strategy should form part of your initial development due diligence.
What Documents Are Required for a Development Application?
This is where many first-time developers significantly underestimate the work involved.
Architectural drawings are normally central to a Development Application, but they are rarely the entire application.
The documentation required depends on the development type, planning controls and physical constraints affecting the site.
A DA package may include:
Architectural plans, elevations and sections;
Feature and level survey;
Site analysis;
Planning report or Statement of Environmental Effects;
Landscape plans;
Civil and stormwater plans;
Traffic and parking assessment;
Waste management plan;
Sustainability documentation;
Cost estimate;
Geotechnical investigation;
Flood or hydraulic assessment;
Bushfire assessment;
Arborist report;
Acoustic assessment;
Heritage impact assessment;
Contamination investigation;
Ecological assessment;
Other specialist reports requested by the relevant authority.
NSW guidance, for example, identifies architectural plans, owner consent, a Statement of Environmental Effects, survey information, site analysis and potentially landscape, drainage and specialist technical reports as part of the documentation that may be required.
That does not mean every project needs every consultant.
The correct consultant team should be determined by the development and site.
A flood-affected property may require hydraulic engineering.
A bushfire-prone site may require a bushfire assessment.
A development affecting significant trees may require an arborist.
A larger residential or commercial development may require a traffic engineer.
A site with difficult levels may require early geotechnical, structural and civil engineering input.
This is why property development due diligence should happen before detailed DA documentation begins.
Why the Town Planner Is Important
Developers sometimes assume the architect manages everything associated with obtaining approval.
In reality, architecture and town planning perform different functions.
The architect or building designer develops the physical design.
The town planner considers the statutory planning framework that determines whether that design can be supported.
Depending on the jurisdiction, this may involve investigating:
Building height;
Density or floor-space controls;
Setbacks;
Parking requirements;
Subdivision controls;
Heritage;
Environmental overlays;
Neighbourhood character;
State planning policies; and
Local planning requirements.
For more complicated developments, the planner may also prepare the planning justification supporting particular aspects of the proposal.
The distinction is fundamental:
A well-designed building is not necessarily an approvable development.
And an approvable development is not necessarily a financially viable development.
The developer needs to consider both.
Should You Have a Pre-Lodgement Meeting?
For larger or more complicated projects, a pre-lodgement meeting can be one of the most useful steps in the development approval process.
Before spending heavily on detailed documentation, the developer and consultant team can present the preliminary concept to the relevant authority and seek feedback.
Potential issues may include:
Density;
Building height;
Setbacks;
Vehicle access;
Parking;
Stormwater;
Flooding;
Heritage;
Landscaping;
Subdivision;
Environmental constraints; or
Additional technical reports.
Queensland treats pre-lodgement as sitting outside the formal DA Rules process, while Victoria similarly encourages early discussions with the relevant council planning department to establish whether a permit is required and what information should accompany the application.
From a development perspective, the commercial logic is straightforward:
Finding a major planning problem at concept stage is considerably cheaper than discovering it after completing the DA documentation.
What Happens After a Development Application Is Lodged?
The exact procedure differs between states, councils and development types, but a typical development assessment process may involve:
Lodgement → Initial Review → Assessment → Referrals → Information Requests → Public Notification → Determination
In NSW, for example, the process progresses through lodgement and assessment before determination, with council assessing the proposal against relevant planning controls and considering matters such as public submissions and agency referrals where applicable.
Queensland describes five key parts within its formal development assessment process:
Application;
Referral;
Information request;
Public notification; and
Decision.
Not every stage applies to every Queensland application.
For developers, one of the most important stages to understand is the information request.
What Is an Information Request?
An Information Request — sometimes referred to differently between jurisdictions — occurs when the assessing authority or another relevant agency requires additional information before completing its assessment.
This might require:
Amended architectural drawings;
Further flood modelling;
Traffic analysis;
Environmental assessment;
Clarification of planning issues;
Revised landscaping;
Additional stormwater information; or
Responses to issues identified during assessment.
Receiving an information request does not automatically mean the DA is heading towards refusal.
However, it can have significant commercial consequences.
Additional information can mean:
More design work.
More time.
More holding costs.
More interest.
And potentially a different development outcome.
This is why a coordinated and well-prepared DA submission matters.
What Happens if Neighbours Object to Your DA?
Neighbour objections are another area that property developers often misunderstand.
Public notification requirements vary according to the jurisdiction, development type and assessment pathway.
Some applications require formal public notification; others do not.
Queensland provides a useful example. Code assessable and impact assessable developments follow different assessment requirements, with public notification applying to impact assessment under the applicable process.
An objection also does not automatically mean the development will be refused.
The relevant authority assesses submissions as part of the broader statutory assessment process.
Nevertheless, developers should anticipate common issues such as:
Privacy;
Overlooking;
Overshadowing;
Traffic;
Parking;
Noise;
Building bulk; and
Neighbourhood character.
Where possible, these matters should be considered during the design process rather than discovered after notification begins.
DA Approval Does Not Always Mean You Can Start Construction
This is one of the most important distinctions for new developers.
Planning approval and construction approval are not necessarily the same thing.
In NSW, development consent obtained through the DA process is generally followed by further approval steps before building work commences, including obtaining the appropriate Construction Certificate.
The process can ultimately extend through to the Occupation Certificate before the completed building can be occupied.
Victoria makes the distinction particularly clear: a planning permit is not a building permit, and a development may require both.
South Australia has another structure again, where development approval may involve planning consent, building consent and/or land division consent depending on the proposal.
For developers preparing programmes and finance models, this distinction matters enormously.
“DA approved” does not necessarily mean “construction starts next week.”
There may still be substantial design, certification and consent conditions to satisfy.
How Development Approval Differs Across Australia
There is no single Australian Development Application process.
While the general objective of land-use planning is similar, each jurisdiction has its own planning legislation, terminology and assessment framework.
State/Territory | Common terminology | What property developers should understand |
New South Wales | Development Application / Development Consent | Multiple approval pathways exist, including exempt and complying development. A full DA is not always required. |
Victoria | Planning Permit | A planning permit is separate from a building permit. VicSmart provides a streamlined process for eligible applications. |
Queensland | Development Application / Development Approval | Development can be accepted, assessable or prohibited, with different assessment requirements applying to different development. |
Western Australia | Development / Planning Approval | Local planning schemes play an important role, while different assessment and decision-making pathways may apply to particular developments. |
South Australia | Development Application / Development Approval | Development approval can involve planning consent, building consent and/or land division consent. |
Tasmania | Development Application / Planning Permit | Requirements are influenced by the applicable planning scheme and the particular development and site. |
ACT | Development Application | Development assessment operates through the Territory planning framework rather than the conventional council structure found in many states. |
Northern Territory | Development Application / Development Permit | Development applications operate under the Territory planning system, with the relevant decision-maker depending on the proposal and location. |
The practical lesson is simple:
Knowing how to obtain development approval in Sydney does not mean you automatically understand the process in Brisbane, Melbourne, Perth or Adelaide.
Always investigate the planning framework applying to the actual property.
How Can a Development Application Affect Your Feasibility?
This is where the DA becomes particularly important for property developers.
Planning is not simply a compliance issue.
Planning can fundamentally change your development feasibility.
Imagine purchasing a site based on a preliminary feasibility for six townhouses.
Your assumptions are:
6 townhouses × $1.5 million = $9 million GRV
But during planning and technical investigations, you discover that site constraints and planning requirements make the original scheme unrealistic.
The viable design becomes five townhouses.
You haven't necessarily lost the ability to develop the property.
But you may have lost $1.5 million of assumed gross realisation value before construction has even started.
Now imagine the revised development also requires:
Substantial retaining walls;
Additional stormwater infrastructure;
Road upgrades;
Flood mitigation;
Additional consultant reports; and
Another six months to obtain approval.
Revenue has decreased.
Costs have increased.
Finance costs have increased.
The development programme has extended.
Your original feasibility may no longer represent the project you are actually delivering.
The development approval determines what you can build. The feasibility determines whether it is worth building.
The two should never be considered independently.
The Conditions of Development Consent Matter Too
Developers understandably focus on one question:
“Did we get the DA?”
But an approval can contain numerous conditions.
Those conditions may require additional engineering, consultant documentation, infrastructure works, contributions, environmental measures, service upgrades or other requirements before particular stages of the project can proceed.
Some approvals can also require specific matters to be resolved before the consent becomes operative.
The better question is therefore:
“What exactly has been approved, what conditions apply, and what will satisfying those conditions cost?”
The answer should feed directly back into the development feasibility, programme and construction budget.
Who Coordinates the Development Application?
As projects become larger, consultant coordination becomes increasingly important.
A townhouse or apartment development could involve:
Architect;
Town planner;
Surveyor;
Structural engineer;
Hydraulic engineer;
Landscape architect;
Traffic engineer;
Arborist;
Geotechnical engineer;
Acoustic consultant; and
Other specialists.
Each consultant may be competent in their own discipline.
But somebody still needs to ensure they are all designing and reporting on the same project.
Consider what happens when:
The architect changes the basement configuration.
The traffic engineer is still assessing the previous parking layout.
The civil engineer is working from an outdated site plan.
The landscape architect proposes trees over stormwater infrastructure.
The planner's report refers to superseded dwelling numbers.
Council then receives an application containing conflicting information.
This is not necessarily a consultant competency problem.
It is a development management problem.
How OwnerDeveloper Approaches Development Applications
At OwnerDeveloper, we don't view the DA as an isolated council approval exercise.
It forms part of the broader property development strategy.
Our Development Management approach considers the relationship between:
Site Acquisition → Due Diligence → Feasibility → Planning Strategy → Design → Development Approval → Procurement → Construction → Completion
Before committing significant capital to design and consultant documentation, developers should understand:
What can realistically be developed on the site?
What approval pathway applies?
What planning controls affect the property?
What physical and environmental constraints exist?
What specialist consultants are required?
What infrastructure may be necessary?
What could delay the approval?
What could the consent conditions add to the project cost?
Does the proposed development still support the original feasibility?
Most importantly:
Does the development still make commercial sense?
Because the objective is not simply to obtain an approval.
The objective is to obtain an approval for a development that can be financed, constructed, marketed and delivered profitably.
Don't Start With the DA. Start With the Development Strategy.
A Development Application is one of the most important milestones in property development.
But it should not be the point where you first discover what your site can actually accommodate.
Before purchasing or committing significant capital to a development property, investigate the planning controls, approval pathway, physical constraints, infrastructure requirements and realistic development yield.
Then test those assumptions through a proper development feasibility.
Then progress the design.
Then assemble the right consultant team.
Then prepare the planning application.
And when approval is finally received, review the conditions and update the feasibility again before proceeding into construction.
Because:
A DA isn't just a set of drawings. It's the case for why your development should be allowed to proceed.
And for a property developer, the most important question isn't simply:
“Can I get this development approved?”
It is:
“Can I get the right development approved — and will it still make money?”
Planning a property development? OwnerDeveloper can help assess the site's development potential, test the feasibility, establish the approval strategy and coordinate the consultant team through planning and project delivery.
Don't spend thousands designing the wrong development. Understand the site, approval pathway and numbers before you commit.
Frequently Asked Questions
What is a Development Application (DA)?
A Development Application is a formal request seeking approval to carry out development on a particular property. Depending on the project, it may include architectural plans, planning reports, surveys, engineering documentation and specialist assessments demonstrating how the proposed development responds to applicable planning requirements and site constraints.
Do all property developments require a DA?
No. The approval pathway depends on the state or territory, the proposed development and the property itself. In NSW, for example, some projects may qualify as exempt development or complying development, while others require development consent through a full DA.
What documents are normally required for a Development Application?
Requirements vary considerably, but a DA may include architectural drawings, a site survey, planning report or Statement of Environmental Effects, stormwater plans, landscape plans and specialist reports covering matters such as traffic, flooding, bushfire, heritage, trees, contamination, acoustics or geotechnical conditions.
Is a Development Application the same across every Australian state?
No. Australia does not have one national DA system. NSW commonly uses Development Applications and Development Consent, Victoria generally refers to Planning Permits, while Queensland uses its own Development Application and Development Approval framework. Each state and territory has different legislation, terminology, assessment procedures and approval pathways.
Can a Development Application affect the profitability of a property development?
Absolutely. The approval process may change dwelling yield, floor area, parking, setbacks or infrastructure requirements, while conditions of consent can introduce additional costs. These changes can affect GRV, construction costs, finance costs, programme and ultimately development profit, which is why planning strategy and development feasibility should be considered together.
