Why ISO Auditing Is Worth Pursuing
If you are asking how to become an ISO auditor, you are probably already working in quality, safety, or environmental management and wondering whether auditing could be your next step. The short answer is yes, and the path is more accessible than most people realise.
On this page
ISO auditors are in genuine demand across Australia. Organisations certified to ISO 9001, ISO 14001, and ISO 45001 all need competent people to run internal audits, and certification bodies need trained auditors to conduct third party assessments. That demand is not going away. If anything, it is growing as more organisations pursue certification to win tenders, satisfy clients, and meet regulatory expectations.
This guide walks you through the full picture: what ISO auditors actually do, the different levels of auditor, what training you need, how to build your experience, and how to move from your first internal audit to a credentialled auditing career.
What Does an ISO Auditor Actually Do?
Before you invest time and money in training, it is worth being clear about what the job involves. An ISO auditor collects and evaluates evidence to determine whether a management system conforms to a standard and is operating effectively. That sounds straightforward, but the practical reality involves a mix of planning, interviewing, document review, observation, and clear written communication.
On any given audit day, you might be reviewing procedures in the morning, walking a production floor in the afternoon, and writing findings in the evening. You are not there to catch people out. You are there to give an honest, evidence based assessment of how the system is working.
The auditor role sits across three main types of audit:
- First party audits are internal audits conducted by or on behalf of the organisation itself. These are required by every major ISO standard and are typically where most people start their auditing career.
- Second party audits are supplier or customer audits. One organisation audits another as part of a commercial relationship. These require more interpersonal confidence than internal audits but follow the same fundamental process.
- Third party audits are conducted by independent certification bodies. Only registered auditors working for accredited certification bodies can conduct these. This is the top of the auditing career ladder for most people.

The Three Levels of ISO Auditor Training
ISO auditor training is structured in levels, and understanding which level suits your situation is the first practical decision you need to make.
Foundation Level
A foundation course introduces you to the requirements of a specific ISO standard without going into audit technique in depth. It is a good starting point if you are new to ISO standards and want to understand what the standard requires before learning how to audit against it. Foundation training is not a prerequisite for internal auditor training at most providers, but it gives you a solid base if you have no prior exposure to the standard.
Internal Auditor Level
This is where most people begin their practical auditing journey. An internal auditor course covers the audit process from planning through to reporting, with a focus on conducting audits within your own organisation. You will learn how to write audit plans, conduct interviews, gather evidence, identify nonconformities, and write findings clearly.
Internal auditor training is typically two to three days and does not require you to have previous audit experience. It is accessible to quality managers, HSE advisors, environmental coordinators, and anyone else responsible for running a management system. If you are wondering where to start, this is usually the right answer.
For a detailed look at what this path involves, the article on how to become an ISO internal auditor covers the process step by step.
Lead Auditor Level
Lead auditor training prepares you to plan and lead audits conducted by a team. It is a more intensive course, typically five days, and includes practical exercises, role plays, and a formal examination. Completing a recognised lead auditor course is the foundation for third party auditing careers and is also highly valued in senior internal roles.
Lead auditor courses are accredited by bodies such as Exemplar Global and IRCA. Completing an accredited course gives you a certificate of attainment that you can use to apply for personnel certification and, eventually, registration as an auditor with a certification body. If you are weighing up the two levels, the comparison article on ISO Lead Auditor vs Internal Auditor lays out the differences clearly.
Which ISO Standard Should You Train In First?
The three most common ISO standards for auditor training in Australia are ISO 9001 (quality), ISO 14001 (environment), and ISO 45001 (occupational health and safety). All three share the same High Level Structure, which means the audit process is essentially the same across all of them. The differences lie in the subject matter and the specific requirements you are auditing against.
The practical answer is to start with the standard most relevant to your current role. If you are a quality manager, start with ISO 9001. If you work in health and safety, start with ISO 45001. If you are in environmental management, start with ISO 14001.
Once you have your first qualification, adding a second or third standard is straightforward because you already understand the audit methodology. Many experienced auditors hold credentials across all three standards, which makes them more versatile and more employable.
What Qualifications and Experience Do You Need?
There is no single mandatory qualification required to become an ISO auditor, but there are practical requirements that training providers and certification schemes expect you to meet.
Education
Most lead auditor courses require you to hold a qualification at the level of a completed secondary education or higher. Some providers set higher bars, particularly for third party auditor registration. However, relevant work experience can often substitute for formal education, especially at the internal auditor level. A degree is not required to become a competent ISO auditor, and many excellent auditors have come from trade or technical backgrounds rather than university.
Work Experience
Practical experience in a relevant field matters more than academic qualifications in most auditing careers. Certification schemes like Exemplar Global require you to demonstrate a minimum number of years of work experience and a certain number of completed audits before you can register as a certified auditor. The specific requirements vary by scheme and grade, but in general you will need at least two to four years of relevant work experience and a documented audit log showing audits you have conducted or participated in.
Audit Experience
This is where many people get stuck. You need audit experience to register as an auditor, but you need to be an auditor to get audit experience. The practical solution is to start conducting internal audits within your own organisation as soon as you complete your internal auditor training. Every internal audit you conduct counts toward your experience log. You can also participate in supplier audits as an observer or team member, which builds your experience and your confidence before you take on a lead role.
The Certification Schemes: Exemplar Global and IRCA
Two main schemes recognise ISO auditor credentials internationally: Exemplar Global and IRCA. Both are respected and both are recognised by certification bodies in Australia and overseas. The choice between them often comes down to which scheme your training provider is accredited with.
Exemplar Global is widely used in Australia and the Asia Pacific region. IRCA has historically been stronger in the United Kingdom and Europe but is well recognised globally. If you are planning to work primarily in Australia, Exemplar Global recognition is generally sufficient. If you have ambitions to work internationally or with organisations that specifically require IRCA credentials, that is worth factoring into your decision.
Both schemes require you to complete an accredited training course, accumulate a documented audit log, and apply for registration at the appropriate grade. Maintaining registration requires ongoing continuing professional development, typically measured in hours per year.
Building Your Audit Experience: Practical Steps
Training gives you the knowledge and framework. Experience is what turns you into a capable auditor. Here is how to build it systematically.
Start With Internal Audits in Your Organisation
If you work for an ISO certified organisation or one that is working toward certification, volunteer to conduct internal audits. Speak to your quality or compliance manager about getting involved. Most organisations struggle to find enough people willing to conduct internal audits, so the offer is usually welcomed.
Document every audit you conduct. Record the date, the standard, the scope, the processes audited, your role, and the duration. This is your audit log, and you will need it when you apply for personnel certification.
Participate in Supplier Audits
If your organisation conducts supplier audits, ask to join as an observer or team member. Second party auditing is excellent experience because it puts you in a different environment with people you do not know, which is closer to what third party auditing feels like. It also demonstrates versatility on your CV.
Seek Witness Audit Opportunities
Some certification bodies allow aspiring auditors to observe real certification audits as a witness. This is not always easy to arrange, but if you have a contact at a certification body or know a lead auditor who works for one, it is worth asking. Witnessing a real certification audit gives you a clear picture of the standard expected at the third party level.
Keep a Reflective Audit Journal
After each audit, write a brief reflection. What went well? What was harder than expected? What would you do differently next time? This practice accelerates your development and gives you material to draw on when applying for registration or preparing for job interviews.
Moving Into Third Party Auditing
Third party auditing, working for a certification body to conduct ISO certification audits, is the most demanding but also the most rewarding path for experienced auditors. It requires a completed lead auditor course from an accredited provider, a documented audit log meeting the certification body's requirements, and usually a formal application and competence assessment process.
Certification bodies in Australia include SAI Global, Bureau Veritas, SGS, LRQA, and several others. Each has its own application process, but all will want to see your training certificate, your audit log, your work history, and evidence of your technical competence in the industries you plan to audit.
Most certification bodies also require you to complete a witness audit, where an experienced auditor observes you conducting an audit and assesses your performance. This is not a test you can cram for. It reflects the quality of your preparation, your interviewing skills, your ability to gather evidence, and how you handle unexpected situations on the floor.
The article on ISO auditor career path from internal auditor to lead auditor goes into more detail on what this progression looks like in practice.
What Skills Make a Good ISO Auditor?
Technical knowledge of the standard is necessary but not sufficient. The auditors who do this job well share a set of practical skills that are harder to teach in a classroom but can absolutely be developed with experience.
- Listening: The ability to hear what someone is actually saying, not just what you expected them to say, is the foundation of good audit interviewing. Most of the evidence you gather comes through conversation.
- Questioning: Knowing when to ask an open question, when to probe, and when to move on is a skill that develops with practice. Good auditors do not interrogate. They create a conversation that naturally surfaces evidence.
- Observation: Walking a facility and noticing what is actually happening, not just what is documented, requires attention and curiosity. The gap between the procedure and the practice is often where the real findings live.
- Written communication: Writing a nonconformity that is clear, specific, and defensible is harder than it sounds. Auditors who write vague or poorly evidenced findings create problems for everyone.
- Composure: Audits can be tense. Auditees sometimes get defensive. Findings get challenged. The ability to stay calm, professional, and evidence focused under pressure is something every auditor needs.
ISO Auditor Salary and Career Prospects in Australia
The financial case for building ISO auditing credentials is solid. Internal auditors working within organisations typically earn salaries in line with quality, safety, or environmental management roles. Lead auditors working for certification bodies or operating as contractors can earn significantly more, particularly once they have built a reputation and a client base.
Contract auditing rates in Australia vary depending on the standard, the industry, and the auditor's experience, but experienced lead auditors can command strong day rates that make the career financially attractive. For a detailed breakdown of what you can expect to earn at different career stages, the article on ISO auditor salary in Australia is worth reading before you make your career decisions.

If you are ready to move forward, here is a practical sequence to follow.
- Identify the ISO standard most relevant to your current role or industry.
- Complete an internal auditor course with a recognised training provider. Look for providers whose courses are accredited by Exemplar Global or IRCA.
- Start conducting internal audits within your organisation and document each one carefully.
- Once you have a few audits under your belt, consider completing a lead auditor course if your career goals include third party auditing or senior internal roles.
- Build your audit log systematically and apply for personnel certification once you meet the experience requirements.
- If you are interested in third party auditing, research certification bodies in Australia and understand their specific application requirements.
The path from first training course to credentialled auditor takes time, but every step builds on the last. The auditors who progress fastest are the ones who treat every internal audit as a genuine learning opportunity rather than a box to tick.
