Bendigo Council's Image Audit Uncovers Hundreds of Duplicate Photos Across City's Digital Records

City of Greater Bendigo staff this week completed the first stage of a long-delayed audit of the municipality's digital image archive, identifying more than 400 duplicate or near-duplicate photographs embedded across planning documents, heritage registers and public communications records dating back to at least 2019. The problem has been quietly compounding administrative workload inside the Lyttleton Terrace civic offices for the better part of two years.

The duplication issue matters now because Bendigo Health's capital expansion program and the ongoing review of Aboriginal cultural heritage sites across the Dja Dja Wurrung country around Bendigo require clean, accurately catalogued photographic records. Duplicate images stored under different file names inside the council's document management system have, in a number of cases, been lodged as separate supporting attachments in planning applications — creating compliance questions about whether assessors reviewed identical rather than distinct evidence. The Victorian Planning Authority has been flagging document integrity requirements more closely across regional councils since updated guidelines took effect in March 2026.

The audit was carried out by council's records and information management team in coordination with staff at the Bendigo Art Gallery on View Street, which shares a heritage asset documentation workflow with the council's planning directorate. The gallery has its own digitisation program running in parallel — a project that has catalogued more than 12,000 items from the permanent collection since 2023. Duplication errors in that stream, while less numerous, raised early alarms that eventually prompted the broader municipal-level review. La Trobe University's Bendigo campus on Edwards Road has also been drawn into discussions; its library services team has an existing data integrity agreement with the council covering local history image collections held jointly under the Goldfields Libraries network.

What the Audit Found

The 400-plus duplicates represent roughly 14 percent of the active image records reviewed in this first stage, according to internal documentation circulated to councillors ahead of this Tuesday's ordinary council meeting. That figure covers only records created or modified since January 2022; a second-stage review covering the full archive back to 2015 is scheduled to begin in August. Staff have so far replaced or merged 178 of the confirmed duplicates, with the remainder flagged for manual verification before any files are altered — a precaution required under the council's records management policy because some images carry heritage overlay annotations that cannot be reconstructed if a file is deleted in error.

The practical cost is not trivial. Council officers have estimated that duplicate image handling added an average of 1.8 hours per complex planning application processed through the Bendigo CBD heritage overlay precinct — the network of streets including Pall Mall, View Street and the Hargreaves Mall precinct — over the 12-month period to June 2026. Across the roughly 340 heritage-overlay applications lodged in that period, that adds up to a significant administrative burden, and it partly explains why median assessment times for heritage applications in Bendigo crept above state benchmarks earlier this year.

Fixes Underway, but Full Resolution Is Months Away

Council is now rolling out a deduplication protocol borrowed from a pilot program Colac Otway Shire ran in late 2025, adapted for Bendigo's larger archive. The process uses file-hash comparison to flag exact duplicates automatically, while perceptual-hash tools flag visually similar images for human review. Both tools are already installed in the council's network environment; the main constraint is staff time, not software.

Anyone who has lodged a planning application in the past 18 months and received a request for further information citing image discrepancies should contact the council's Development Services team at the Lyttleton Terrace offices directly. Officers have been told to prioritise callback responses within two business days for any applicant whose file was touched by the audit. The second audit stage, covering the pre-2022 archive, is expected to produce a final report to council by November. Until then, applicants submitting new heritage-overlay applications are being asked to label all photographs with unique file names and GPS coordinates before lodgement — a small step that, according to the internal documentation, would have prevented the majority of the 400 duplicates identified this week.
