Proxy Advisory Firms: Should Australian Investors Take These Quiet Powerbrokers Seriously?

Proxy advisory firms occupy an unusual position in Australian markets being amongst arguably the most influential powerbrokers but are neither regulators nor shareholders. They are peculiar to say the least

How are they influential?  Their recommendations can swing AGM outcomes, shape board behaviour, and influence the fate of multi‑billion‑dollar transactions. They sit in the background of every proxy season, issuing voting guidance, dissecting governance failures, and occasionally triggering boardroom upheaval. The question for investors is whether these firms deserve the weight they are given, or whether their influence reflects a market structure that has outsourced too much judgement to a handful of private actors.

Australia’s most prominent proxy advisory firm, Ownership Matters, is the clearest case study. Its research, voting guidelines, and governance scoring models are widely read by institutional investors, and its commentary often sets the tone for governance debates. The firm positions itself as a commercially savvy governance adviser with more than 20 years of corporate memory, offering services that help investors “promote an intelligent, evidence‑based public debate,” “use shareholder rights to their advantage,” and “identify governance risk” across the ASX300.

But the real test of a proxy adviser’s relevance is not its mission statement. It is whether its work has meaningfully shaped outcomes. And in Australia, the answer is increasingly yes.

Proxy Advisory Firms

Proxy advisers emerged to solve the dilemma that institutional investors (i.e. big super funds and other money managers like Wilson and Regal) hold hundreds of positions and cannot individually analyse every resolution at every AGM…but each and everyone of them can matter and so outsourcing the research to specialists became efficient. Over time, however, the dynamic shifted. Proxy advisers became not just researchers but de facto governance arbiters. Their recommendations influence how super funds vote, and super funds collectively hold enough of the market to matter.

Ownership Matters’ governance research illustrates this influence. Its Governance Concerns Index (GCI), which scores ASX300 companies across seven governance risk factors (including accounting risk, board quality, related‑party risk, dilution risk, and executive pay structure) feeds directly into institutional voting decisions.

When a company scores poorly, boards know it. When a remuneration report is flagged as problematic, dissent follows. And when a major transaction raises governance concerns, proxy advisers can catalyse shareholder backlash.

The 2025 proxy season demonstrated how sensitive the market has become to governance signals. Although average support for management remained high at 93.5%, the year was defined by a dramatic shareholder revolt at James Hardie Industries. Investors voted down three directors, rejected the remuneration report, and opposed an increase in non‑executive director fees—largely in response to the company’s US$8.8bn acquisition of AZEK, completed without shareholder approval after an ASX waiver.

Proxy advisers did not cause the revolt, but their analysis amplified it. Their scrutiny of governance processes, transaction structures, and board accountability helped crystallise investor concerns. The episode was significant enough to prompt the ASX to review its listing rules on shareholder approval requirements.

This is the kind of structural influence that makes proxy advisers impossible to ignore.

Who are the top proxy advisory firms?

Australia’s proxy advisory market is relatively concentrated. We already mentioned Ownership Matters which is most locally focused of the group we will mention, with deep ASX expertise and a strong emphasis on governance risk identification. Its research program is underwritten by subscribers and includes analysis of capital raisings, board composition, audit matters, and takeover practices.

We’ll note 3 more. The first of which is CGI Glass Lewis which is Australian arm of global proxy adviser Glass Lewis. It provides voting recommendations to many large super funds and has a strong influence on remuneration and ESG‑related resolutions.

Secondly, ISS (Institutional Shareholder Services) which is another global heavyweight with an arm downunder. ISS provides governance ratings, ESG scoring, and voting recommendations. Its global methodology sometimes clashes with local norms, but its reach is extensive.

And finally, the ACSI (Australian Council of Superannuation Investors). Now, it is not a proxy adviser in the commercial sense, but a governance body representing major super funds so it makes the list because it acts similar to the way others would. ACSI issues voting recommendations and engages directly with boards on ESG and governance issues.

For all these firms, their influence is magnified by the structure of Australia’s superannuation system: compulsory contributions create large, professionally managed pools of capital that rely on external research.

Have proxy advisory firms achieved anything, ever?

Of course. Look no further than the James Hardie revolt. No it did not stop James Hardie going ahead with the Azek acquisition but the episode forced the ASX to review its listing rules, demonstrating how governance pressure (supported by proxy analysis) can reshape regulatory settings. We’d argue if it weren’t for the proxy advisory firms, our regulators would not have responded.

History is littered with other examples and not just restricted to takeover deals. Ownership Matters has a long history of scrutinising capital raisings, particularly placements that dilute existing shareholders. Its research during periods of emergency capital raising relief highlighted how expanded placement capacity could result in significant dilution, especially when conducted alongside entitlement offers or SPPs.

This work has influenced investor expectations around transparency, fairness, and the use of placement capacity. Companies know that aggressive dilution will attract proxy scrutiny and potential voting backlash.

Sticking with Ownership Matters, one of its activities is studies on board composition across the ASX300, covering independence, gender, tenure, and director shareholdings. These have shaped investor expectations about what a modern board should look like. Its research has highlighted persistent issues, such as male‑dominated chairs and CEOs, despite improvements in independence and gender diversity.

These findings feed directly into voting decisions on director elections. While not all recommendations become policy, the idea that the firm’s has at least some influence on governance discourse cannot be denied.

Do Proxy Advisers Have Vested Interests?

This is a question not many ask, but arguably we should. You see, proxy advisers are paid by institutional investors, not by companies. This reduces the risk of conflicts arising from issuer‑paid research. Ownership Matters explicitly positions itself as a governance adviser for institutional investors, not a consultant to boards.

However, the subscription model creates its own incentives: firms must produce research that is perceived as valuable, rigorous, and occasionally contrarian. A proxy adviser that never recommends against management would quickly lose credibility.

The concentrated nature of the industry means a small number of firms can influence large swathes of the market. This has led to periodic political scrutiny, including attempts to regulate or restrict proxy advisers’ operations. Ownership Matters itself has criticised interventions aimed at “silencing the proxy advisory industry.”

This highlights the risk of over‑reliance on a few private entities.

Should Investors Take Proxy Advisers Seriously?

Time to cut to the chase. The short answer is yes—but with nuance. Proxy advisers provide depth, continuity, and governance expertise that many investors cannot replicate internally. Their research identifies governance risks ahead of the mainstream, as Ownership Matters notes in its monitoring of issues such as pay for value, foreign control, capital raisings, and takeovers.

They also help enforce accountability. When boards push the boundaries of governance norms—whether through aggressive capital raisings, opaque transactions, or poor remuneration structures—proxy advisers amplify investor scrutiny.

Of course, caution Is warranted. Investors should not outsource judgement entirely. Proxy advisers operate within their own frameworks, which may not always align with an investor’s strategy, risk tolerance, or time horizon. Global firms like ISS and Glass Lewis may apply methodologies that do not fully reflect Australian market nuances.

Moreover, proxy advisers are not infallible. Their influence can create herding behaviour, where investors follow recommendations without conducting their own analysis.

The most sophisticated investors treat proxy advice as an input, not an instruction and that is what we would recommend. They use it to: identify governance red flags, benchmark board practices, understand the implications of complex transactions and pressure boards to justify their decisions

But they ultimately vote based on their own assessment of long‑term value. They do not outsource thinking to proxy advisory firms. This may sound obvious, but several trends suggest proxy advisers will remain influential and there is the risk of this happening. We see mandatory climate reporting as a key event – this will increase the complexity of ESG‑related votes, making external research more valuable. Regulatory reviews, such as the ASX’s examination of shareholder approval requirements, will keep governance issues in the spotlight.

Superannuation consolidation will concentrate voting power further, increasing the impact of proxy recommendations.

At the same time, political scrutiny will continue. Proxy advisers operate in a contested space where corporate interests, investor rights, and regulatory frameworks intersect.

The Bottom Line

Proxy advisory firms like Ownership Matters have become essential components of Australia’s governance ecosystem. They are not perfect, and they are not neutral. But they provide a level of scrutiny, expertise, and continuity that materially improves market transparency and accountability.

Investors should take them seriously—but not uncritically. The best use of proxy advice is as a catalyst for deeper analysis, not a substitute for it. In a market where governance failures can destroy billions in value, ignoring the insights of specialised governance researchers is a luxury few investors can afford.
