Every council keeps a public record of what it has approved, refused and conditioned on other people's land. In Ipswich that record sits in Development.i, the council's public development application register. A decided DA on the same street, or on a similarly zoned lot nearby, tells you something a zoning map alone cannot: what council actually approved, and what it made the applicant do to get there. This page is a plain workflow for finding and reading one, not a planning-rules page. It does not tell you what your own site can do; a site-specific check or a town planner does that.
What Development.i is
Development.i is Ipswich City Council's public register of development applications, from lodgement through to decision, reachable directly at developmenti.ipswich.qld.gov.au. Every application lodged with council, whether it is eventually approved, refused, or withdrawn, is recorded there with a reference number, a short description of what was proposed, and a status.
The register covers material change of use applications (a new or changed use, such as a dual occupancy or a multiple dwelling), reconfiguring a lot (subdividing, consolidating or realigning boundaries), and other assessable work such as operational works or building work assessed against the planning scheme. It does not cover every building approval a private certifier issues without council assessment; those sit outside this register.
Searching by address or application number
The register's address search is the normal starting point: enter the street address, or the suburb if you are scanning an area rather than one lot, and it returns the applications recorded against that land. If you already have a specific reference, from a listing, a neighbour, or a council notification, searching by that application number goes straight to the one record.
Most registers, Development.i included, let you narrow results to decided applications rather than everything ever lodged. That filter matters: a live, undecided application tells you what has been asked for, not what council has agreed to. For understanding a precedent, it is the decided applications, approved or refused, that carry the finished decision and its conditions.
Reading the application number
Ipswich application numbers follow a consistent pattern once you know what to look for: a sequence number, the year, and a type suffix, for example 8005/2023/RAL or 12623/2025/MCU. The suffix tells you what kind of application it is:
- MCU, material change of use, a new or different use of the land (a dual occupancy, a multiple dwelling, a home business, and similar).
- RAL (sometimes shown as RaL), reconfiguring a lot, meaning a subdivision, a lot consolidation, or a boundary realignment.
- OD, an assessable operational or building works application, for example works or building elements that fall outside a standard house build and need assessment against the scheme.
You may see the same number written with slashes or with hyphens depending on which part of the system displays it (8005/2023/RAL and 8005-2023-RAL refer to the same application). Knowing the suffix before you open a record tells you, at a glance, what kind of application it is, without reading the full description first.
Which documents to open first
Once you have an application open, most registers list its documents rather than showing them inline, and Development.i is no different: expect a documents list attached to the record. Two documents matter more than the rest combined. The decision notice is council's formal outcome, approved, approved with conditions, or refused, plus the reasons, and it is the single document that tells you what was actually decided rather than merely proposed. The approved plans and conditions carry the real detail: stormwater and drainage requirements, road or access works, setbacks, landscaping, staging, and infrastructure contributions. Two similar-sounding proposals can carry very different conditions depending on the lot's own constraints.
Beyond those two, the information request correspondence (Ipswich records this as a "Further Advice" request and response) is worth reading. This is where council asks the applicant to fix, clarify or justify something before it will decide, and it shows exactly what council queried on that site, stormwater, access geometry, lot dimensions, ecology, or something specific to that block, often more revealing than the final conditions because it shows the sticking points along the way, not just the resolved outcome.
What a decided DA tells you, and what it does not
A decided DA near your block is real evidence of how council has treated a similar proposal on similarly constrained land: what it approved, what it refused, and what it demanded by way of conditions. That is useful, grounded information, not a guess about the scheme. What it does not do is answer your question automatically. Every lot carries its own zoning, overlays and dimensions, and a precedent from one lot does not transfer whole to another; reading what a nearby decision means for your specific block is the site-specific work a report or a town planner does, not something a register search resolves by itself. Treat a decided DA as a data point to bring into that conversation, not as the answer to it.
This page is general information about how to use a public register, not advice about your property. Register interfaces and the documents attached to any one application can change. Do not rely on this page for a specific property. Get a site-specific report or independent professional advice before acting. We work with town planners, not in place of them: where a pathway depends on design or professional judgement, a town planner or the relevant qualified professional confirms it for your specific proposal.
Want the answer for your block, not just the register listing? Our $690 site-specific report reads the zone, every overlay mapped on the property and the surviving development pathways for one property, with every figure cited to the scheme. Not ready for that?
