During the first year of the COVID-19 pandemic, the state of Queensland, Australia, had relative success in containing viral transmission, presenting a unique case for potential insights into effective crisis management. Limited research exists into the communication style and effectiveness of Chief Health Officers (CHOs) throughout pandemic scenarios. Using an adapted Crisis Emergency and Risk Communication (CERC) framework based on 12 themes which indirectly assess domains of trust, credibility, transparency, and accountability. A content analysis of 107 press conferences dating from January 30th to December 24th, 2020 was conducted to analyze crisis communication style delivered by the Queensland CHO and guest speakers. Our analysis found that most communication aligned with the CERC framework, suggesting that adherence to CERC themes in crisis communication may have played an important role in the state’s success. However, areas which were lacking included themes relating to efforts to address, search and gather knowledge. Analysis also revealed that some CERC themes overlapped or were missing, thus triggering the development of a modified framework to provide a more succinct coding model. Our findings demonstrate the importance communication plays in successful crisis management and the modified framework can be applied to analyze communication at national and sub-national levels.
