Thousands of duplicate images are sitting inside ACT government and federal agency databases right now, quietly inflating storage costs, slowing down service portals and — in some cases — causing residents to receive contradictory information about their own records. The problem is mundane, unglamorous and, according to digital records specialists, almost entirely preventable.
The issue has surfaced again this week as the ACT Government's Service Canberra continues a multi-year digital transformation program that touches everything from rates notices to planning approvals. When the same scanned document, photograph or form image gets uploaded twice — or migrated from a legacy system without deduplication — the downstream effects ripple out in ways most residents never see until something goes wrong.
The Australian National University's College of Engineering and Computer Science has produced research in recent years examining how data redundancy in public sector systems affects service delivery speed. The broader academic consensus, reflected in guidance from the Australian Digital Health Agency and the Digital Transformation Agency in Canberra's Nishi building on New Acton's Constitution Avenue, is that unmanaged image duplication is among the cheapest problems to fix yet one of the last to get funded.
At the federal level, Services Australia — headquartered on Hobart Place in the city centre — processes millions of document images each year tied to welfare, Medicare and aged care claims. When duplicate images persist in a claimant's file, staff can spend additional minutes per case resolving discrepancies. Across a workforce of tens of thousands of processing officers, those minutes compound.
What the Cleanup Actually Involves
Deduplication software compares image files using hash matching — a process that identifies byte-for-byte identical copies — and flags near-duplicates for human review. The technology is not new. What's changed is the sheer volume of scanned material held by agencies following pandemic-era digitisation drives between 2020 and 2022, when ACT government offices and federal departments accelerated document scanning to support remote workforces.
The ACT Government's digital records framework, updated in 2023 under the Territory Records Act 2002, requires agencies to maintain accurate and accessible records — but it does not prescribe specific technical standards for image deduplication. That gap is where problems accumulate. Storage costs for unoptimised government cloud environments are not trivial: industry benchmarks suggest duplicate content can account for between 20 and 40 percent of total stored data in organisations that have undergone rapid digitisation without accompanying cleanup protocols.
For Canberra residents, the practical stakes are highest when records underpin time-sensitive decisions. A duplicate passport photo in an ACT driver licence application, a doubled rates assessment scan, a duplicated development application image in the Environment, Planning and Sustainable Development Directorate's systems — each represents a small but real friction point that erodes public confidence in digital government.
The ACT Library and Archives, based in Parkes, has been working through a backlog of digitised historical records where duplication is a known issue, particularly in collections migrated from earlier platforms.
Residents who suspect their records contain errors — including possible duplicate documents — can lodge a request through Access Canberra or contact the relevant agency directly. For federal records, the Office of the Australian Information Commissioner on Marcus Clarke Street in the city handles complaints about record accuracy under the Privacy Act 1988. Checking your MyGov document history periodically is a low-effort way to catch obvious duplications before they affect a claim or application. The fix, when it comes, starts with someone noticing the problem exists.
