ACT Government's Duplicate Image Problem: The Key Decisions That Will Define What Comes Next

The ACT Government's digital records management program is facing a reckoning. Auditors reviewing the territory's asset and property databases have identified widespread duplication of imagery files across multiple directorates — a technical mess that is inflating storage costs, slowing down planning approvals, and complicating the land release pipeline at a moment when Canberra's housing supply has never mattered more.

The problem did not emerge overnight. Years of siloed IT purchasing across directorates — from the Environment, Planning and Sustainable Development Directorate on Constitution Avenue to Transport Canberra and City Services — meant that departments built separate image libraries using incompatible tagging systems. When those systems were partially merged after 2021, duplicate files were carried across rather than resolved. The result, according to a review process now underway inside the directorate, is redundant image sets clogging servers that also handle time-sensitive documents tied to developments in Gungahlin and Belconnen.

Why This Matters for Housing and Planning

The timing is particularly awkward. The ACT Government is under sustained pressure to accelerate land releases across the territory's north and northwest growth corridors. Development applications in Gungahlin's Kenny and Jacka precincts, along with infill projects near the Dickson group centre, require clean, accurately indexed imagery to move through the planning system efficiently. When duplicate or mislabelled images attach to the wrong parcel record, planning officers must manually verify before approving — a step that can add days or weeks to each application cycle.

The ACT's 2024-25 Budget allocated approximately $18.7 million to the territory's broader digital transformation agenda, a portion of which was earmarked for records modernisation across planning and land management functions. Duplicate image remediation was not originally a line item in that program, which means the directorate must now decide whether to absorb the cost within existing allocations or seek a supplementary appropriation in the 2026-27 Budget, due to be handed down in August.

At the Australian National University's 3A Institute on the Acton campus, researchers have spent several years examining exactly this kind of technical debt in government data systems. The broader academic literature on public sector data quality consistently points to deduplication as one of the highest-return digital investments available — but only when organisations commit to a governance framework that prevents the problem recurring. Without that framework, remediation exercises become a recurring expense rather than a one-time fix.

The Decisions That Will Shape the Outcome

Three choices are now sitting with senior officials. First, the directorate must decide whether to run a bulk automated deduplication sweep — fast, cheap, but carrying a real risk of deleting images that appear identical but relate to different property records — or a slower manual-and-machine hybrid process with human sign-off at each stage. The hybrid approach is estimated to take up to nine months if applied to the full database, pushing completion into mid-2027.

Second, officials must determine which external procurement pathway to use. The ACT Government's whole-of-government digital panel, established under the Digital Strategy 2025-2030, includes several vendors with deduplication tooling. Selecting from that panel avoids a fresh procurement process but limits the field. Going to open tender could yield a better technical fit but would add at least three months before a contract is signed.

Third, and most consequentially for Canberrans dealing with the planning system day to day, the directorate must decide whether to pause certain Gungahlin and Belconnen development application streams while remediation runs, or to continue processing applications on the existing — flawed — database and reconcile records afterwards. Pausing protects data integrity but risks deepening the housing supply lag. Continuing risks compounding errors that will need untangling at settlement.

A decision on the approach is expected before the end of July, ahead of the August Budget process. Residents and developers with active applications in affected precincts — particularly those referencing land parcels in Kenny, Jacka, and the Northbourne Avenue corridor — should contact the planning directorate directly to confirm their application's status is unaffected. The ACT Civil and Administrative Tribunal also handles disputes where planning delays cause demonstrable harm, an avenue that applicants' solicitors in Civic have already flagged as a contingency if timelines slip significantly.
