The KPMG Australia scandal that erupted publicly in March 2026 represents one of the most significant integrity crises to hit the Big Four in Australia since the PwC tax leaks affair.
This remains a fast-moving and ongoing story. New articles will be added over the coming weeks as regulatory investigations advance, further client decisions emerge, and additional leadership or governance developments come to light.
Audit quality lies at the heart of public trust in the Big Four. Big4News examines audit failures, inspection findings, independence, professional scepticism, quality control and the standards that shape confidence in financial reporting.
Deloitte, PwC, EY and KPMG are investing heavily in technology and AI, building AI-enabled services for clients and positioning themselves as trusted advisers on automation, governance and digital transformation. But these developments also raise difficult questions about quality control, cybersecurity, professional judgment, accountability and client reliance.
This page brings together Big4News coverage of technology and AI across the Big Four, including generative AI, hallucinated reports, unreliable citations, automation claims, data breaches, digital transformation, audit and consulting risks, governance failures and the wider implications for professional services.
Governance determines how decisions are made, while accountability determines who answers for them. Big4News examines leadership, oversight, transparency, ethics, partnership structures and the mechanisms that hold Deloitte, PwC, EY and KPMG to account.
Whistleblower Files brings together Big4News reporting on those who raised concerns inside the Big Four and their clients—and what happened next. Coverage includes retaliation allegations, failed hotlines, internal investigations, surveillance and the weaknesses of formal whistleblower protections.
Big4News examines workplace culture across Deloitte, PwC, EY and KPMG, including performance management, wellbeing, redundancy programmes, parental leave, harassment, morale and the gap between corporate values and employees' lived experience.
