Canberra's Digital Archives Are Drowning in Duplicate Images — and the Numbers Show Why It's Getting Worse

ACT government agencies and Canberra-based federal departments are sitting on digital asset libraries bloated with duplicate images, with industry benchmarks suggesting that between 30 and 40 per cent of files stored in unmanaged media repositories are redundant copies of the same original. For a public-sector city that runs on documentation, the cost is not trivial.

The issue is coming to a head in mid-2026 partly because of storage pricing. Enterprise cloud storage contracts — the kind that anchor the digital operations of agencies along London Circuit and across the Barton precinct — have been repriced upward over the past 18 months as global data centre demand has surged. That makes every redundant gigabyte more expensive to hold than it was two years ago, and internal IT teams are under pressure to clean house before the next budget cycle.

What the Data Actually Looks Like

Digital asset management specialists who work with large organisations describe a recognisable pattern: an original photograph is downloaded, renamed, re-cropped, re-exported, and then stored again — often in multiple shared drives — by different staff members who have no visibility over what their colleagues already hold. Multiply that workflow across a team of 200 public servants over three years and the duplicate count compounds rapidly.

The Australian National University's IT services division, which manages digital assets for research outputs, communications, and administrative records across its Acton campus, has previously flagged deduplication as a priority in its internal infrastructure reviews. The University of Canberra, operating out of Bruce, faces similar pressures given the volume of marketing imagery, research photography, and event documentation it generates each year.

Industry figures from digital asset management vendors place the average cost of storing one terabyte of enterprise cloud data in the Australian market at roughly $25 to $40 per month, depending on redundancy tiers and retrieval speeds. For an agency holding, say, 20 terabytes of largely unaudited media files — a modest figure for a mid-sized federal department — the annual storage bill for files that include 35 per cent duplicates could mean $3,000 to $5,000 per year spent on data that serves no operational purpose.

The ACT Government's whole-of-government digital strategy, anchored through the Digital Strategy 2030 framework released in 2022, identifies data quality and asset governance as priority areas. Duplicate content is a data quality problem — it inflates apparent holdings, distorts metadata search results, and creates version-control confusion when communications teams are trying to source approved imagery quickly.

Deduplication Tools and What Comes Next

The mechanics of fixing the problem are well understood, even if the political will to allocate staff time to the task is harder to find. Automated deduplication tools — software that scans a repository using perceptual hashing algorithms to identify visually identical or near-identical images regardless of filename or format — can process a 10-terabyte library in a matter of hours. The challenge is not technical. It is governance: deciding which version of a duplicated image is the master copy, who has authority to delete the others, and how to prevent the same fragmented workflows from recreating the problem within 12 months.

Organisations that have run structured deduplication programs typically report reducing their active image libraries by 25 to 45 per cent in the first pass. For agencies that pay per-seat licensing fees for digital asset management platforms — common in the federal government precinct around Kings Avenue and Constitution Avenue — a smaller, cleaner library can also reduce licensing costs if those platforms tier their pricing by asset count or storage volume.

For Canberra's public servants sitting on shared drives stuffed with five variations of the same ministerial headshot or six slightly different crops of a Gungahlin Town Centre development photo, the practical advice is straightforward: run a deduplication audit before the next storage contract renewal, establish a single named owner for each image collection, and build a naming convention that makes version history visible at a glance. The numbers make the case without needing much argument — storing the same file four times costs four times as much, and in a tightening fiscal environment, that is a number that tends to get attention.
