How Hobart Is Tackling the Digital Duplicate Problem, and Where It Sits Against Cities Doing It Better

Hobart City Council's digital asset registers contain thousands of duplicated images, redundant photographs of streetscapes, heritage buildings, and infrastructure sites that clog planning portals, slow environmental assessments, and cost staff hours to manually reconcile. The problem is not unique to Hobart, but the pace at which the city is addressing it puts it behind comparable mid-sized cities in Europe and Canada that have already deployed automated deduplication systems across municipal platforms.

The timing matters. Tasmania's planning and regulatory environment is under unusual strain right now. The Marinus Link undersea cable project, the prolonged AFL stadium debate at Macquarie Point, and ongoing disputes over salmon aquaculture licensing have all generated enormous volumes of photographic and geospatial documentation lodged with state and local agencies. When image libraries are bloated with duplicates, planners and decision-makers working from those systems are slower to respond, and more prone to referencing outdated or mismatched visual records.

What Hobart Is Actually Doing

The council's Digital Infrastructure Renewal Program, flagged in its 2025-26 budget cycle, allocated funding toward an audit of the city's document and media management systems. That audit, understood to be ongoing as of mid-2026, covers council-managed repositories including those used by planners working on developments along Macquarie Street, Elizabeth Street, and the waterfront precinct between Franklin Wharf and Brooke Street Pier. The Libraries Tasmania network, headquartered in Murray Street, has separately been running a heritage image deduplication project since early 2025, targeting digitised collections from the State Library of Tasmania that contain significant numbers of near-identical photographic scans.

Automated deduplication, where software identifies and flags visually identical or near-identical image files without requiring manual review, is now standard practice in cities like Amsterdam, where the municipality's open-data portal processed more than 1.2 million images through automated systems between 2022 and 2024, according to the Amsterdam Digital City programme's published annual report. Calgary, Alberta, completed a comparable overhaul of its civic media library in 2023, cutting redundant storage by 34 percent across municipal departments. Hobart, by contrast, has not yet publicly reported equivalent metrics from its own audit.

Wellington, New Zealand, a city of similar size to Hobart and facing analogous heritage documentation pressures, completed a full transition to hash-based deduplication software across its city council systems in March 2025. Wellington's digital records team has publicly credited the shift with reducing image processing time for resource consent applications by roughly 20 percent. Hobart planning staff dealing with the volume of documentation attached to the Macquarie Point Development Corporation's stadium proposal alone would recognise why that kind of efficiency gain matters.

The Practical Stakes for Tasmanians

This is not purely a back-office IT issue. When a heritage property owner in Battery Point lodges a development application, the images attached to that application pass through council systems where duplicates, sometimes dozens of near-identical photographs from different submission stages, can delay automated processing and trigger manual review queues. Community groups opposing or supporting projects near Sullivan's Cove have previously raised concerns, at public meetings, about response times from planning authorities. Streamlined image management is one lever, rarely discussed publicly, that directly affects those timelines.

The Tasmanian state government, under the current Liberal administration, has broadly supported digital modernisation across service delivery, though specific commitments to deduplication tooling within planning infrastructure have not been outlined in any public budget paper reviewed by The Daily Tasmania. A tender for document management system upgrades was listed on the Tenders Tasmania portal earlier this year, with a closing date of 28 February 2026; the outcome of that process has not been publicly announced.

What comes next will likely depend on whether the council's digital audit produces a public-facing report with measurable targets, something Wellington and Calgary both did before committing to vendor contracts. Without that transparency, Hobart risks continuing to fall behind cities that moved earlier and published their results. Residents and community organisations with business before the planning system would do well to ask, at the next round of council budget consultations, exactly where that audit stands.
