Code of Ethics

IIA-Australia Code of Ethics


The purpose of The Institute's Code of Ethics is to promote an ethical culture in the profession of internal auditing.

A code of ethics is necessary and appropriate for the profession of internal auditing, as it is founded on the trust placed in its objective assurance about governance, risk management and control. The Institute's Code of Ethics amplifies three of the Core Principles:
  • Demonstrates integrity.
  • Demonstrates competence and due professional care.
  • Is objective and free from undue influence (independent).
The Code of Ethics has two components:
  • Principles that are relevant to the profession and practice of internal auditing
  • Rules of Conduct that describe behaviour norms expected of internal auditors. These rules are an aid to interpreting the Principles into practical applications and are intended to guide the ethical conduct of internal auditors

Applicability and Enforcement

This Code of Ethics applies to both individuals and entities that provide internal auditing services.

For Institute members and recipients of or candidates for IIA-Australia professional certifications, breaches of the Code of Ethics will be evaluated and administered according to The Institute's by-laws and administrative guidelines. The fact that a specific practice is not mentioned in the Rules of Conduct does not prevent it from being unacceptable or discreditable, and therefore, the member, certification holder, or candidate can be subject to disciplinary action.


Internal auditors are expected to apply and uphold the following principles:

The integrity of internal auditors establishes trust and thus provides the basis for reliance on their judgement.

Internal auditors exhibit the highest level of professional objectivity in gathering, evaluating, and communicating information about the activity or process being examined. Internal auditors make a balanced assessment of all the relevant circumstances and are not unduly influenced by their own interests or by others in forming judgements.

Internal auditors respect the value and ownership of information they receive and do not disclose information without appropriate authority unless there is a legal or professional obligation to do so.

Internal auditors apply the knowledge, skills, and experience needed in the performance of internal auditing services.
