With nearly half of the world’s population living in the cities, many city and local governments are seeking to deploy smart solutions to their everyday city operations through the implementation of smart city services. However, the subject of smart city services has always been associated with trustworthiness of the services by its users due to security and privacy concerns. These issues may have a major impact on the smart city services adoption. The aim of this proposed research is to examine the technology, organisational, environment, and security determinants that influence stakeholders’ trust towards their intention to adopt smart city services in Australian regional cities. For this, Technology-Organisation- Environment framework together with security related factors for ensuring stakeholders’ trust will be tested using both quantitative and qualitative data. Structural equation modelling technique will be carried out using Smart PLS to test the presented hypotheses and the results will be finally discussed.
