Deloitte Australia Auditor Profile
Deloitte Australia is one of the country's largest professional services firms, with offices in Sydney, Melbourne, Brisbane, Perth, Adelaide, Canberra, and other major cities. The firm provides comprehensive audit, consulting, financial advisory, risk management, and tax services, with particularly strong practices in government, financial services, and technology.
What Deloitte Australia Does Well
Government and IRAP expertise is a major differentiator. Deloitte Australia has IRAP-endorsed assessors on staff and regularly performs assessments for cloud service providers and technology companies serving Australian government agencies. This capability, combined with Essential Eight maturity assessments, makes the firm a natural choice for government-adjacent compliance.
Mining and resources sector knowledge is uniquely strong. Australia's resource-heavy economy means Deloitte Australia has built specific compliance expertise for mining, energy, and infrastructure companies that face both operational technology security challenges and traditional information security requirements.
End-to-end cybersecurity services from strategy through to compliance assessment provide clients with a comprehensive view of their security posture. Deloitte Australia's Cyber Intelligence Centre adds threat intelligence capabilities that inform compliance recommendations.
Engagement Process
Deloitte Australia follows the global Deloitte methodology: strategic planning and risk assessment, detailed control testing, findings management, quality review, and report delivery. For IRAP assessments, the firm follows ACSC-prescribed methodology with additional security clearance requirements.
