The latest swathe of resignations of senior leaders at KPMG Australia ( Tuesday, 23 June), including its chairman following allegations concerning the misuse of confidential client information, represent far more than another corporate governance failure. They are the latest reminder of a lesson that organisations repeatedly seem destined to relearn: trust is both the most valuable and the most fragile asset any institution possesses.

The allegations surrounding KPMG’s handling of confidential information obtained through its relationship with Lendlease have once again raised serious questions about professional ethics, stewardship, and accountability. These developments follow closely on the heels of the PwC Australia scandal, where confidential government tax policy information was allegedly used to assist private-sector clients in ways that breached the trust placed in the firm.

Although the circumstances differ, the underlying issue is remarkably similar. In both cases, individuals and organisations were entrusted with privileged information because of their professional role. The expectation was clear: that information would be protected, used only for its intended purpose, and never leveraged for personal, commercial, or competitive advantage.

When that expectation is violated, the consequences extend far beyond the individuals involved. At its heart, the issue is not about information itself. Information is merely the vehicle. The real issue is trust.

Every day, organisations are entrusted with information that holds immense value. Clients share strategic plans, commercial negotiations, intellectual property, financial forecasts, board discussions, vulnerabilities, risks, and future intentions. Governments disclose sensitive policy information. Employees reveal concerns, ideas, aspirations, and challenges. Stakeholders provide confidence, support, and goodwill.

These exchanges occur because people believe that the recipients of that information will act responsibly. The moment information is used for a purpose beyond that for which it was entrusted, the relationship fundamentally changes.

Many of the most significant organisational failures in history were not caused by individuals who were unaware of the rules. They were caused by individuals who understood the rules perfectly but gradually convinced themselves that an exception was justified. Yet every ethical failure begins with a small compromise between principle and convenience. Over time, those compromises accumulate until conduct that would once have been unthinkable becomes normalised.

This is why the KPMG and PwC matters are so significant. They are not merely stories about professional misconduct; they represent a fundamental failure of corporate culture- a culture which leaders are expected to embed and role model through their own conduct.

The legal consequences of such actions can be substantial. Organisations may face regulatory investigations, civil litigation, contractual disputes, financial penalties, reputational damage, loss of clients, and exclusion from future government or commercial opportunities. Leaders may lose their positions, professional standing, and careers.

Yet these legal consequences are often the least enduring. The deeper damage occurs within the organisation itself.

Trust, once broken, rarely remains confined to the individuals directly involved. It spreads quietly and often invisibly through the organisation, influencing behaviours, relationships, decisions, and perceptions long after the original breach has occurred. Like a crack in a foundation, it may not be immediately visible from the outside, but over time its effects can be felt throughout the entire structure.

For employees, trust is not an abstract concept. It is the invisible contract that underpins their daily work. Employees commit their skills, energy, loyalty, and often a significant part of their identity to the organisations they serve. In return, they expect leadership to act with integrity and to uphold the values it promotes.When those expectations are violated, disillusionment emerges.

Employees begin to question whether organisational values are genuine commitments or merely words displayed on websites, annual reports, and office walls. Confidence in leadership diminishes. Pride in the organisation gives way to disappointment. The emotional connection that drives commitment, initiative, and discretionary effort begins to weaken.

The effects are often subtle at first.

Engagement declines.

Conversations become more guarded. People become less willing to challenge decisions or raise concerns. The willingness to innovate diminishes because psychological safety has been eroded. Employees begin protecting themselves rather than contributing fully to the collective success of the organisation.

Over time, the cultural consequences can be profound. High-performing individuals who value integrity may choose to leave. Future talent may look elsewhere. Recruitment becomes more difficult. Retention becomes more expensive. Cynicism gradually replaces commitment. What was once a culture of trust becomes a culture of caution.

The consequences extend beyond employees. Investors rely on trust when assessing risk. Customers rely on trust when deciding where to spend their money. Business partners rely on trust when deciding with whom they will collaborate. Regulators rely on trust when determining the level of oversight required. Communities rely on trust when granting organisations their social licence to operate.

And rebuilding trust is far more difficult than rebuilding systems. Trust cannot be demanded. It cannot be purchased. It cannot be imposed through regulation or policy. It must be earned through repeated demonstrations of integrity, accountability, transparency, and stewardship.

Trust sits at the centre of leadership, governance, culture, and performance because every meaningful relationship within an organisation depends upon it.

The most successful organisations understand that trust is not built through mission statements, compliance frameworks, or public declarations of values. It is built through thousands of decisions, large and small, made every day by leaders and employees alike. It is demonstrated when organisations protect information even when no one is watching. When they place principle ahead of expediency. When they encourage transparency. When they hold themselves accountable. When they recognise that stewardship is a responsibility, not a privilege.

The true test of leadership is not how leaders behave when circumstances are favourable. It is how they behave when presented with opportunities to benefit from information, influence, or access that others do not possess.

The events at KPMG, just as the events at PwC before them, should serve as a reminder to every board, executive team, professional adviser, public institution, and private enterprise that trust is never guaranteed. It must be earned continuously and protected diligently.

In the end, organisations will not be judged solely by their financial performance, market position, or technical capability. They will be judged by whether they can be trusted. Because while information creates opportunity, trust creates legitimacy.

And without legitimacy, no success is truly sustainable.
