RMA Australia is pleased to bring you our second July event – Demystifying Internal Audit, hosted by Westpac.
Internal audit as a partner in better risk management Internal audit is not just an oversight function and it plays a key role in strengthening risk management capability. By providing independent assurance and constructive challenge, audit helps organisations identify weaknesses early and reinforces disciplined risk practices across the business.
When organisations view audit as a partner, they unlock greater value. Engaging openly, sharing context, and aligning on outcomes enables teams to extract practical insights that enhance controls and processes. This collaborative approach ultimately leads to stronger, more resilient risk management and better customer and business outcomes.
Demystifying this process helps teams move from reactive to proactive. By understanding what audit looks for; clear accountability, evidence of control effectiveness, and strong governance, teams can better position themselves for success and reduce surprises. Ultimately, it builds confidence that risk is being managed in a consistent and sustainable way.
By the end of this session, participants will be able to:
1. Understand the role of Internal Audit in strengthening risk management capability.
2. Recognise opportunities to partner with Internal Audit to enhance controls and risk practices.
3. Apply audit insights to strengthen governance, controls, and risk management outcomes.
This event will be followed by a 30min in-person catered network event.
Please join us either in person in Sydney or via Webinar. For those attending in Sydney, the event will be followed by networking drinks and canapes from 5:00pm-5:30pm.
Limited seats are available in Sydney.
