Cybersecurity Governance in Australian Corporate Disclosures
Research Focus: This project analyzes how Australian ASX-listed companies discuss cybersecurity in their earnings calls and investor communications. We examine board involvement, regulatory references, and the specificity of cybersecurity disclosures over time.
Using a hybrid pipeline (regex gating plus LLM labeling), we extract and classify cybersecurity-related statements from transcripts spanning 2015 to 2025.
