Grant Thornton Australia is an independently-owned assurance, tax and advisory firm with over 1,500 people across six offices in Australia. It's a member firm of the Grant Thornton global network, and its core services span audit, tax, risk consulting, forensics, M&A, corporate finance, insolvency, restructuring, and sustainability advisory.
For security practitioners, the most relevant surfaces here are Risk Consulting and Forensics. The threat model is less about defending a single product perimeter and more about advising clients on theirs - risk posture assessments, incident response, forensic investigations, and the compliance and governance layers that wrap around them. The advisory context means engagements vary: you're diagnosing exposure across different architectures, industries, and maturity levels rather than tuning the same SIEM every quarter.
Grant Thornton Australia was the first professional services firm in the country to implement a 9-day fortnight with no salary reduction. The firm operates on what it calls CARE values - Collaboration, Authenticity, Responsibility, and Excellence. As a mid-tier player in a market dominated by Big Four incumbents, it trades on agility and a culture that claims to prioritize people and community alongside client work. The security and risk practice sits inside that broader advisory machine, which means the work intersects with forensics teams, corporate finance due diligence, and M&A risk assessments depending on the engagement.
