RSM Australia

For more than a century, RSM Australia has helped organisations navigate risk, adapt to change and achieve their strategic objectives. Like many of the businesses we support, we started small. From a husband-and-wife duo in Perth, we have grown into one of Australia’s leading professional services firms, with 32 offices nationwide and more than 1,900 professionals supporting clients across metropolitan and regional Australia. RSM Australia's Cyber Security team helps organisations identify, manage and respond to cyber risks in an increasingly complex threat landscape. Combining deep technical expertise with practical business insight, we work with clients to strengthen cyber resilience, enhance governance, meet compliance obligations and protect critical systems and data.Our approach is built on long-term, collaborative relationships. In 2026, RSM Australia was named Client Choice – Best Accounting & Consulting Services Firm (>$300m) for the eighth consecutive year.
