This report assesses the adoption of sustainability reporting and social accounting by companies listed on the Australian Securities Exchange (ASX). It examines the application of accounting theories such as agency theory, signalling theory, legitimacy theory, and stakeholder theory in the context of sustainability reporting. The research identifies regulatory, sustainability, and ethical issues related to this adoption, focusing on the risks and opportunities associated with these practices. The study aims to analyze annual reports and sustainability reports of ASX-listed companies like Wesfarmers, Woolworths, and Telstra to determine the extent of incorporation of sustainability reporting and social accounting in their business practices. The research employs a conceptual framework based on prior literature, a theoretical framework incorporating relevant accounting theories, a methodological framework involving data extraction from company reports, and an analytical framework for interpreting the collected data to answer key research questions about the prevalence, types, and frameworks used in sustainability reporting by ASX-listed firms. The data is sourced from annual reports, sustainability reports, and CSR reports of the selected companies.
