Smart City Tech: Navigating the Balance Between Innovation and Public Privacy

The Central Coast is increasingly defined by the intersection of traditional infrastructure and data-led technology. Through the Smart Central Coast Program, which ran from 2023 to 2025 with funding from the NSW Department of Planning, Housing and Infrastructure, the region has been testing how digital solutions can influence economic growth and regional equity. While proponents highlight the efficiency of these systems, the shift toward a data-integrated city creates new challenges regarding how public information is gathered and used.

Infrastructure and the Data Network

Local government is moving to embed the Internet of Things, big data, and smart grid technology into the regional landscape. Council strategic planning documents underscore the intent to use these tools to foster growth, though these systems require a robust framework for open data sharing and security. In the Gosford and Terrigal CBDs, the installation of 450 smart parking sensors-250 in Terrigal and 200 in Gosford-aims to reduce traffic congestion by helping drivers locate available parking via mobile apps. This effort to manage high-traffic zones reflects a broader reliance on real-time data to solve legacy urban problems.

Beyond transit, the push for smarter systems has reached commercial utility management. In June 2024, the Central Coast Council launched a smart metering programme. This initiative equipped 100 high-usage commercial businesses with digital water meters. By connecting these devices to the MyWater dashboard, the council enabled businesses to receive real-time alerts for leaks and consumption. While this provides tangible benefits for resource conservation, it also marks a transition where commercial usage patterns are tracked with higher precision than previously possible.

Safety, Surveillance, and Future Integration

The implementation of smart technology for safer cities presents perhaps the most sensitive ethical considerations. The region has trialled projects such as the 'Benchmark NSW' experimental outdoor smart seating initiative, developed in partnership with UNSW and MIT. These interventions aim to improve perceptions of safety for women and gender-diverse people in public spaces. Similarly, the Safer Cities: Her Way Program utilised sensor data monitoring and lighting upgrades, which reports indicate increased visitor numbers by 5-6 times during peak hours in Gosford.

As these technologies become more prevalent, the challenge for the Council remains in balancing the promise of improved safety and efficiency with the public’s expectation of privacy. Looking forward, the adoption of additional smart technologies, such as GPS-enabled wayfinding and Bluetooth-connected sensors, will likely continue to reshape the urban experience. The effectiveness of these programs will depend on whether the region can maintain transparency as it scales its use of big data and automated monitoring across its diverse commercial and public spaces.
