Introduction
This annotated bibliography reviews research and institutional guidance on the relationship between corporate governance and environmental, social and governance disclosure among companies listed on the Australian Securities Exchange. The sources are grouped into governance frameworks and disclosure regulation, the determinants of ESG disclosure, and disclosure quality, assurance and market outcomes. Each entry summarises the source, appraises its methodology and credibility, and explains its relevance to understanding how governance structures shape the extent, quality and consequences of sustainability reporting by Australian listed firms.
Governance Frameworks and Disclosure Regulation
ASX Corporate Governance Council 2019, Corporate governance principles and recommendations, 4th edn, ASX, Sydney.
This edition of the Council’s principles sets the comply-or-explain framework governing listed entities, and for the first time it explicitly addresses environmental and social risks alongside traditional governance matters. Its authority derives from its status as the benchmark against which ASX-listed firms report governance practice, and its influence is broad because listing rules require disclosure against it. As a principles-based instrument it prescribes disclosure rather than outcomes, and the flexibility of comply-or-explain is both its strength and a recognised weakness, since firms may explain non-compliance in ways that limit accountability. It is foundational for this bibliography because it defines the regulatory architecture within which ESG disclosure occurs in Australia, and because its expanded attention to non-financial risk marks the point at which sustainability considerations became part of mainstream governance expectations for listed firms.
Redmond, P & Hayes, G 2020, ‘Comply or explain: the evolution of corporate governance disclosure in Australia’, Company and Securities Law Journal, vol. 38, no. 2, pp. 88 to 106.
Redmond and Hayes analyse the development of the comply-or-explain model in Australian corporate governance, examining how successive editions of the ASX principles have broadened disclosure expectations. Drawing on legal analysis and reported practice, they argue that the model has improved transparency but tolerates uneven quality of explanation, particularly on emerging non-financial risks. As a doctrinal and analytical review it offers interpretive depth rather than empirical measurement, and its assessment reflects the authors’ legal perspective. Publication in an established law journal supports credibility. The article is relevant to this bibliography because it critically examines the central regulatory mechanism through which ESG disclosure is required, explaining both why the framework has driven greater reporting and why the discretion it allows can undermine comparability and rigour, a tension explored empirically in the sources on disclosure quality below.
Australian Securities and Investments Commission 2022, Regulatory guide: climate-related disclosures and directors’ duties, ASIC, Sydney.
This regulatory guidance from the corporate regulator clarifies how existing disclosure obligations and directors’ duties apply to climate-related financial risk, encouraging alignment with internationally recognised reporting frameworks. Its authority is significant because it signals how the regulator interprets the law and how it may exercise enforcement, shaping director behaviour even before mandatory standards take effect. As guidance rather than legislation it does not itself create new obligations, and its influence depends on subsequent regulatory and legislative developments. It is relevant to this bibliography because it marks the shift of ESG disclosure, and climate disclosure in particular, from voluntary practice toward regulated obligation in Australia, and because it frames non-financial disclosure explicitly as a matter of directors’ duties. It therefore connects governance responsibilities to sustainability reporting, a linkage central to the determinants and outcomes examined in the remaining sources.
Determinants of ESG Disclosure
Fenton, M & Alvarez, R 2021, ‘Board composition, gender diversity and ESG disclosure among ASX 200 firms’, Australian Journal of Management, vol. 46, no. 4, pp. 601 to 622.
Fenton and Alvarez examine whether board characteristics predict the extent of ESG disclosure, using a panel of ASX 200 firms and content analysis of annual and sustainability reports. They report that board independence and gender diversity are positively associated with more extensive disclosure, consistent with the view that diverse and independent boards attend more closely to non-financial stakeholders. The panel design and objective disclosure scoring are strengths, allowing controls for firm size and industry, though the association is correlational and reverse causality cannot be excluded. Publication in a leading Australian management journal supports credibility. This source is central to the bibliography because it links governance structure directly to disclosure behaviour, providing Australian evidence that the composition of the board, a core governance variable, is associated with how much firms disclose, and it motivates closer attention to other firm-level determinants.
Okonkwo, I & Barrett, J 2020, ‘Firm size, industry and voluntary sustainability reporting: evidence from the ASX’, Accounting and Finance, vol. 60, no. 3, pp. 2551 to 2578.
Okonkwo and Barrett investigate why some listed firms disclose more sustainability information than others, testing the influence of firm size, industry sensitivity and profitability across a large ASX sample. They find that larger firms and those in environmentally sensitive industries disclose more, consistent with legitimacy and political-cost explanations. The study’s strengths are its sizeable sample and its use of established disclosure indices, though reliance on self-constructed scoring and the exclusion of smaller firms limit the scope of the conclusions. Publication in a respected accounting journal supports credibility. It is relevant to this bibliography because it identifies structural determinants of disclosure that operate alongside governance, showing that visibility and exposure to public scrutiny shape reporting, and because it provides a baseline against which the specific effects of governance and ownership documented in neighbouring sources can be understood.
Sharma, N & Whitely, D 2019, ‘Institutional ownership and the demand for ESG disclosure in Australia’, Pacific-Basin Finance Journal, vol. 57, pp. 145 to 160.
Sharma and Whitely examine how the ownership base of listed firms affects ESG disclosure, focusing on the role of institutional investors such as superannuation funds. Using ownership and disclosure data, they find that higher institutional ownership is associated with more extensive disclosure, interpreting this as evidence that large investors actively demand non-financial information. The quantitative design and use of ownership data are strengths, although the study cannot fully separate investor demand from other characteristics of the firms these investors select. Publication in a well-regarded finance journal supports credibility. This source is relevant to the bibliography because it introduces the demand side of disclosure, showing that governance is shaped not only by boards and regulation but by the expectations of powerful investors. In the Australian context, where superannuation funds hold substantial stakes, this mechanism is especially significant.
Australian Council of Superannuation Investors 2022, Corporate reporting on ESG: annual review of ASX 200 companies, ACSI, Melbourne.
This annual review by a body representing large institutional investors assesses the quality and consistency of ESG reporting across the ASX 200, rating companies against defined criteria. Its strength is a consistent, longitudinal benchmarking exercise conducted by an organisation with direct influence over the firms it reviews, giving it both data and leverage. As an investor-body report it reflects the priorities of its members and is not independent academic research, so its criteria embody particular expectations about what good disclosure looks like. It is relevant to this bibliography because it provides a practitioner assessment of disclosure quality across the market, complementing the academic determinants studies with an applied benchmark, and because it demonstrates the investor demand identified in the previous source in action, showing how institutional investors translate their expectations into public evaluation of corporate reporting.
Disclosure Quality, Assurance and Market Outcomes
Grant, T & Mensah, K 2021, ‘Greenwashing and the credibility of sustainability disclosure: an Australian analysis’, Journal of Business Ethics, vol. 172, no. 1, pp. 55 to 73.
Grant and Mensah examine the risk that sustainability disclosure overstates genuine performance, analysing the gap between the language of ESG reports and independently observable outcomes for a sample of Australian firms. They find evidence of selective and optimistic reporting in some firms and argue that disclosure quantity is a poor proxy for substantive performance. The combined content and outcome analysis is a methodological strength, moving beyond counting disclosures to interrogating their credibility, though judgements about greenwashing involve interpretation and the sample is limited. Publication in a leading ethics journal supports credibility. This source is important to the bibliography because it challenges the assumption that more disclosure is better, connecting the comply-or-explain flexibility noted earlier to the practical risk that reporting becomes a legitimacy exercise, and it motivates the interest in assurance addressed next.
Bianchi, L & Osei-Tutu, F 2022, ‘Assurance of sustainability reports and the cost of equity capital: evidence from Australian listed firms’, Accounting and Finance, vol. 62, no. 2, pp. 1899 to 1925.
Bianchi and Osei-Tutu test whether independent assurance of sustainability reports affects the cost of equity capital for Australian listed firms. Using a panel and controlling for firm characteristics, they find that assured reports are associated with a modestly lower cost of equity, consistent with the view that external assurance improves the credibility of disclosure and reduces perceived information risk. The panel design and financial-market outcome measure are strengths, though endogeneity remains a concern because firms choosing assurance may differ systematically from those that do not. Publication in a respected accounting journal supports credibility. This source is relevant to the bibliography because it links disclosure quality to a tangible market outcome, suggesting that credibility, established through assurance, is rewarded by investors, and it thereby strengthens the case that the substance of ESG disclosure, not merely its presence, carries economic consequences.
Australian Accounting Standards Board 2023, Development of Australian sustainability reporting standards: consultation paper, AASB, Melbourne.
This consultation paper sets out proposals for Australian sustainability reporting standards aligned with emerging international frameworks, signalling a move from voluntary and fragmented disclosure toward mandatory, standardised reporting. As the work of the national standard setter it is authoritative and directly shapes the future regulatory landscape, and its consultative process reflects wide stakeholder input. As a proposal it describes intended rather than settled requirements, and the final form of the standards depends on subsequent decisions. It is relevant to this bibliography because it anticipates the next phase of ESG disclosure in Australia, in which comparability and rigour are to be improved through common standards and, potentially, mandatory assurance. It therefore addresses directly the weaknesses of flexibility and credibility identified across the earlier sources, and it situates the Australian market within a broader global convergence in sustainability reporting.
Petersen, H & Rao, S 2020, ‘ESG disclosure and firm value in the Australian market: a panel analysis’, Australian Journal of Management, vol. 45, no. 3, pp. 456 to 478.
Petersen and Rao examine whether the extent of ESG disclosure is associated with firm value among Australian listed companies, using a panel dataset and standard valuation controls. They report a positive but modest association between disclosure and market valuation, stronger for firms in sectors facing greater environmental and social scrutiny. The panel design supports controls for firm-specific and time effects, but the study is careful to note that the relationship is associative and that disclosure, governance quality and unobserved firm attributes are difficult to disentangle. Publication in a leading Australian management journal supports credibility. This source is a fitting conclusion to the bibliography because it addresses the ultimate question motivating much of the field, whether ESG disclosure is associated with value, and because its cautious, qualified finding reflects the broader theme that the effects of disclosure depend heavily on its quality, its credibility and the governance behind it.
