The Numbers Behind Brisbane's Duplicate Image Problem: What the Data Actually Shows

Brisbane City Council's digital asset register now holds more than 340,000 image files across its planning, infrastructure and communications departments, according to internal procurement documents reviewed by The Daily Brisbane. Roughly 22 per cent of those files — around 75,000 images — are estimated to be functional duplicates: the same photograph stored under multiple filenames, in multiple folders, sometimes across multiple platforms simultaneously.

The figure matters because storage is not free. Enterprise-grade cloud storage contracts used by Queensland local governments typically run between $18,000 and $60,000 annually per terabyte at scale, depending on redundancy requirements and vendor agreements. Duplicate images inflate those costs directly and silently, buried inside procurement line items that rarely attract scrutiny at budget review time.

Why This Is Landing Now

The timing is not coincidental. The state's 2032 Olympics preparation machine has put an extraordinary volume of new photography, render imagery and construction documentation into circulation across agencies. Projects connected to the Cross River Rail delivery authority, the Gabba precinct rebuild and the Olympic Venues Precinct Authority are each generating fresh digital asset libraries. The Queensland Government's procurement framework requires documentation at multiple project milestones, meaning the same site photograph taken on the same day can legally end up filed under a construction report, a communications brief and a ministerial briefing pack — three separate repositories, one image.

At the same time, the South East Queensland population boom is driving similar pressure at the local government level in Logan and Ipswich. Logan City Council's planning department processed more than 8,400 development applications in the 2024–25 financial year, each requiring photographic evidence of site conditions. Ipswich City Council faces comparable volumes along its Ripley Valley and Yamanto development corridors, where subdivision activity has not slowed. Both councils have told developers to submit site images digitally via online portals — a workflow that systematically produces duplicates when applicants re-upload corrected submissions without deleting the originals.

At the state level, the Department of Housing and Public Works flagged digital asset duplication as a cost-efficiency concern in its 2025 Digital Infrastructure Review, a publicly available document tabled in the Legislative Assembly in November 2025. That review did not attach a dollar figure to the problem statewide, but it recommended that agencies adopt automated deduplication tools by July 2027 as part of the broader Queensland Digital Strategy.

What Deduplication Actually Costs — and Saves

Deduplication software is not expensive relative to the problem it solves. Platforms commonly used in Australian government environments, including tools integrated with SharePoint and Microsoft Azure, are typically licensed at between $8 and $15 per user per month at government-volume pricing. For a mid-sized council with 200 active digital asset users, that is a maximum annual outlay of around $36,000. Against a storage bill inflated by tens of thousands of redundant files, the return on investment is typically positive within one financial year.

Brisbane-based digital records firm Veridian Archives, which holds contracts with several South East Queensland local governments, has previously published case study data on its website showing a 19 per cent reduction in active storage consumption for one unnamed Queensland council client after a 90-day deduplication project. The firm operates from offices on Creek Street in the CBD and has worked on records management projects connected to the Queen's Wharf precinct transition.

The practical upshot for councils and agencies still sitting on the problem is straightforward. The Queensland State Archives updated its General Retention and Disposal Schedule for administrative records in 2024, and the new schedule explicitly addresses digital image assets for the first time, requiring agencies to conduct a records audit before the end of each financial year. For Brisbane City Council, Logan and Ipswich, that deadline falls on 30 June 2027. Agencies that have not begun an audit process by late 2026 will face a compressed timeline — and potentially a rushed, more expensive cleanup — in an Olympic preparation period when IT resources are already stretched thin.
