Bendigo Deploys IoT Network While Privacy Advocates Raise Data Collection Concerns

Bendigo has spent years wiring itself into one of Australia’s most ambitious regional smart city experiments. Free Internet of Things networks. Garbage trucks mapping signal dead zones. Smart water stations that beam usage data straight to council servers. The technology works. The harder question, the one city hall, La Trobe University and partner agencies are still wrestling with, is what happens to all that data once the sensors are live.

The city’s Smart City Bendigo Alliance and its membership in the Global Smart City and Community Coalition were pitched as a large-scale proof of concept for regional policy. That was 2017. Nearly a decade later, the infrastructure is real. The ethical and privacy guardrails are still catching up.

Free Network, Real Trade-Offs

Bendigo operates a free LoRaWAN network built with La Trobe University. Signal-strength mapping was done by mounting sensors on garbage trucks and driving them through the city’s streets. Gateways sit at La Trobe University and Ulumbarra Theatre. For citizens, the pitch is straightforward: cheaper utilities, smarter traffic, cooler walking routes. The trade-off is that every device on that network, every water station, every environmental sensor, generates a data point tied to a location, a time and, increasingly, a person.

The city’s first smart water station, connected to the LoRaWAN network, collects live data on usage patterns, park behavior and safety. Coliban Water, which deployed the station, is the first water utility in Victoria to adopt the technology. The data helps manage drought and heat. But it also raises questions about who owns the behavioral information captured by a device sitting in a public park.

Satellites, Street View and the Limits of Consent

Researchers and the City of Greater Bendigo are using a digital platform that layers satellite heat imagery over Google Street View images. The goal is identifying cooler streets for pedestrians and cyclists. That project, led by RMIT University researchers, was announced in late 2019. It’s a clear public health benefit in a city that regularly hits 40-plus degrees Celsius in summer. Yet the methodology, scraping publicly available imagery and stitching it with satellite thermal data, is a reminder that smart city initiatives often gather information without explicit, informed consent from the people walking those streets.

The '100 Gig Bendigo' initiative, which partners with Bendigo Telco to promote the city's 100-gigabit broadband network, aims to close the digital divide and attract digital businesses. Faster internet can widen participation. It also creates a more attractive target for cyberattacks and raises the stakes on data-breach liability for a regional council that may lack the cybersecurity budget of a capital city.

Bendigo’s approach is being watched nationally and internationally precisely because it is a regional proof of concept. If the safeguards here hold, smaller cities across Australia may replicate the model. If they fail, if a network gateway is compromised, or if smart water station data is used for purposes residents never agreed to, the damage to public trust could be felt far beyond central Victoria.

The next step for the alliance and its partners is clearer data-governance frameworks: what gets collected, how long it is retained, who can access it and under what circumstances. Without those answers, Bendigo risks building a smart city that runs efficiently but ethically in the dark.
