Artificial intelligence is not only disrupting industries and businesses, particularly the ones have fallen behind the adoption, but also significantly impacting public life as well. This calls for government authorities pay attention to public opinions and sentiments towards AI. Nonetheless, there is limited knowledge on what the drivers behind the public perception of AI are. Bridging this gap is the rationale of this paper. As the methodological approach, the study conducts an online public perception survey with the residents of Sydney, (...) Melbourne, and Brisbane, and explores the collected survey data through statistical analysis. The analysis reveals that: the public is concerned of AI invading their privacy, but not much concerned of AI becoming more intelligent than humans; the public trusts AI in their lifestyle, but the trust is lower for companies and government deploying AI; the public appreciates the benefits of AI in urban services and disaster management; depending on the local context, public perceptions vary; and the drivers behind the public perception include gender, age, AI knowledge, and AI experience. The findings inform authorities in developing policies to minimise public concerns and maximise AI awareness. (shrink)
