Client Base and Approach

The agency works with a diverse range of clients, from large multinational corporations to domestic organisations and industry associations. Hennessy Advisory’s approach is defined by its commitment to senior-level engagement—clients work directly with experienced consultants rather than junior staff. The firm’s reputation is built on handling sensitive, high-profile matters where discretion and strategic acumen are paramount. Whether guiding a company through a financial disclosure, managing a public controversy, or shaping government policy, the team prioritises clear, actionable advice.

Hennessy Advisory’s methodology is collaborative and customised. The firm does not rely on template solutions; instead, it develops bespoke strategies that align with each client’s specific goals and risk profile. This hands-on approach, combined with a deep understanding of the Australian political and media landscape, makes the agency a trusted partner for organisations that need to protect and enhance their reputation in challenging environments.

Location and Credentials

Hennessy Advisory is headquartered at 100 Harris St in Sydney, New South Wales, Australia. Operating from this central location, the agency serves clients both domestically and internationally. The team’s collective experience spans senior roles in government, corporate communications, and financial PR, giving them a unique perspective on the intersection of business, media, and public policy. Since its founding in 2016, Hennessy Advisory has built a strong track record, particularly in advising clients on matters that require navigating Australia’s regulatory and political frameworks.

The agency’s leadership is composed of professionals who have worked at the highest levels of Australian business and politics, which lends credibility and depth to their counsel.

Who Hennessy Advisory Is a Good Fit For

Hennessy Advisory is best suited for organisations that face complex, high-stakes communications challenges. This includes multinational corporations entering or operating in the Australian market, peak industry bodies needing advocacy support, and companies undergoing significant financial events or reputational crises. The firm is also a strong choice for clients who value direct access to senior consultants and a no-nonsense, results-driven approach. Smaller organisations or startups may find the agency’s focus on senior-level engagement less suited to their scale, but for those with serious communications needs, Hennessy Advisory provides a depth of experience that is hard to match in the Sydney market.
