Canberra's Duplicate Image Problem: What Happens Next and the Key Decisions Ahead

A growing backlog of duplicate and outdated images embedded across ACT government digital platforms is forcing decisions that administrators have deferred for years — and the window for inaction is closing fast. Planning portals, public-facing agency websites, and the ACT's digital land records system all carry layers of replicated imagery accumulated over more than a decade of piecemeal digital upgrades, creating storage costs, accessibility problems, and real confusion for Canberrans trying to navigate official systems.

The timing matters because the ACT government's broader digital transformation program, launched under the Digital Strategy 2025–2028, is now entering its implementation phase. Decisions made in the next six to twelve months about how to audit, consolidate, and replace duplicate imagery will shape how the strategy actually performs — and how much it costs. A protracted delay means remediation work compounds, particularly as new precincts at Gungahlin and the Molonglo Valley continue to generate fresh planning documents, suburb boundary maps, and development application imagery at scale.

Where the Problem Is Most Visible

Two institutions sit at the centre of the immediate debate. The ACT Planning directorate, headquartered on Constitution Avenue in Reid, maintains a public Development Application tracking portal used by hundreds of Canberrans each week. That portal pulls imagery from multiple legacy databases — some predating 2015 — and users regularly encounter duplicate site photos, mismatched aerial maps, and stale street-level images that no longer reflect completed construction. Separately, the Australian National University's library and open-access research repositories on Acton campus have flagged similar duplication problems in digitised collections, where the same images have been ingested multiple times across different cataloguing projects.

The ACT Land Titles Office, which operates under Access Canberra from its Dickson service centre, is also caught in the middle. Title documents increasingly reference imagery that exists in two or more versions across government servers, creating potential ambiguity in property transactions — a sensitivity Canberra's market, where median house prices remain above $900,000, can ill afford.

For residents in growth suburbs — Gungahlin town centre, Casey, and the expanding edges of Molonglo — the practical consequence is that DA portal searches sometimes surface imagery from earlier development stages, giving an incomplete or misleading picture of a site. Community councils in those areas have raised the issue at territory-level consultation sessions during the past year, though no formal resolution has been announced.

The Decisions That Cannot Wait

Three choices will define how this plays out. First, the ACT government must decide whether to run a centralised deduplication audit across all directorates simultaneously or phase the work directorate by directorate. A centralised approach is faster but requires cross-agency coordination that has historically proved difficult in the territory's relatively siloed public service structure. A phased model — starting with planning and land titles, given their public-facing stakes — would take longer but spreads cost.

Second, there is the question of who holds the canonical image. When two versions of the same aerial photograph of, say, the Belconnen town centre or a West Belconnen estate exist across different servers, someone must determine which is authoritative. That decision carries legal weight in planning and titling contexts, and it cannot be delegated to an automated deduplication algorithm alone.

Third, replacement imagery needs a funding source. Cloud storage and new aerial survey contracts are not cheap; commercial aerial photography over Canberra's urban footprint typically costs in the range of tens of thousands of dollars per survey cycle. The ACT's mid-year budget review, expected in late 2026, is the most realistic vehicle for a supplementary appropriation if the government decides to act decisively.

For Canberrans who interact with planning portals or land records, the practical advice is straightforward: cross-check any site imagery against the date stamp on the document, and where currency of imagery matters — particularly for purchase decisions or development planning — contact the relevant directorate directly rather than relying on portal thumbnails. The ACT Planning directorate's public counter on Constitution Avenue in Reid can be reached during business hours. The current situation is workable, but the decisions being made now will determine whether it stays that way.
