Most external auditors work for accounting firms and spend much of the year at client offices rather than their own desk, moving between engagements as reporting deadlines come round. What sets the role apart is independence: the opinion they sign is for shareholders and regulators, not for the organisation's own management, which is the job of an internal auditor. Firms hire steadily from accounting degrees, and audit is the traditional first job for graduates entering the profession.
How much do external auditors earn?
The median full-time salary for an external auditor is $109,400 per annum, before tax, up $22,600 since 2018.
The main driver is the level you reach and whether you have finished the CA or CPA program, since both change what a firm can bill for your work. Firm type matters as well: the large firms, mid-tier firms and state audit offices each set their own bands, and public sector roles often trade some pay for shorter hours. Busy season arrangements vary, with some employers paying overtime and others offering time in lieu.
What does an external auditor do day to day?
The list below is what fills most weeks; the exact mix shifts with seniority and whatever stage the current work is at.
- Planning the testing strategy for an engagement before a single account is checked
- Sampling transactions and controls to see whether the numbers hold up
- Chasing clients and colleagues for the evidence needed to close a file
- Writing up findings and defending an opinion that has to withstand scrutiny
- Working long days through busy season as several clients' reporting deadlines converge

Is the job growing?
About 12,500 people work as external auditors in Australia, and employment is projected to grow 15.9% over the decade to 2035. That's healthy, above-average growth, and the role should stay in solid demand.
How do you become an external auditor?
Here's the path most external auditors take, step by step.
- 1Complete an accounting degree
A three-year bachelor degree accredited by CA ANZ or CPA Australia covers financial reporting, audit and business law, and accreditation means the subjects you pass count towards the professional program later. Some universities offer a combined degree over four years if you want a second field alongside accounting.
- 2Apply for a graduate program at a firm or audit office
The large and mid-tier firms, along with the state auditor-general's offices, recruit a graduate intake roughly a year ahead of the start date. These roles are paid from day one and rotate you through different clients and industries.
- 3Work through the CA or CPA program
The professional qualification takes around three years of study alongside full-time work, combining exams with logged practical experience and a mentor. It is usually the point at which your pay and responsibility step up, and most firms expect it for promotion.
- 4Register with ASIC if you want to sign audits
Signing a statutory audit opinion for a company requires registration as a registered company auditor with ASIC under the Corporations Act. Registration asks for your degree, completed professional qualification, practical experience and a fit-and-proper assessment.

What's it like being an external auditor?
Audit runs on a calendar. Work is steady for much of the year, then compresses into busy season around the June and December year ends, when several clients land at once and full-time hours run past the average of 43 a week. Days pass in spreadsheets and working papers, in client offices and in conversations where you ask people to explain what you are looking at. The people who enjoy it tend to like the structure, the view they get across different businesses, and the moment something does not add up.
What people like
- You see how businesses actually run. Moving between clients means you sit inside a manufacturer one month and a listed retailer the next, learning how each one records revenue, holds stock and pays people.
- The training is broad and portable. Financial reporting, controls and evidence work are the same skills internal audit, forensic accounting and financial control roles ask for, so the first few years open up several directions.
- You start alongside a group of people your own age. Firms hire in cohorts, so there is usually a peer group working through the CA or CPA program at the same time and studying with you.
- Finding the thing that does not add up. A reconciliation that will not settle or a journal entry posted at the wrong time is genuinely satisfying to trace back to its source, and it is often the part auditors remember.
What people find hard
- Busy season compresses the year. The work does not spread evenly. June and December deadlines stack on top of each other, and the weeks either side run long in a way that is hard to plan around.
- You depend on other people's paperwork. Clients are busy running their own business, so evidence arrives late and you spend part of most weeks following up people who are not answerable to you.
- Junior work can be repetitive. First-year tasks lean heavily on vouching, ticking and tying, and the judgement that makes the job interesting comes with more experience.
- Time away from your own desk. Client site work and travel between engagements means you are often in someone else's office, with their systems and their meeting rooms, rather than settled in one place.

Will AI replace external auditors?
Audit sits in the moderate range. The sampling, documentation and routine checking that fill a junior auditor's week are increasingly handled by analytics tools and working paper platforms, while the professional judgement at the centre of an opinion is not. What changes is the volume of manual verification, so the entry-level work looks different from a decade ago; what does not change is that a registered auditor has to weigh the evidence and sign.

Common questions about becoming an external auditor
Straight answers to the questions people ask most.
How much does an external auditor earn?
External auditors earn $109,400 per year before tax at the median. Pay rises with the level you reach and whether you have completed the CA or CPA program, and firm type matters, since the large firms, mid-tier firms and public sector audit offices set their own bands.
How do I become an external auditor?
Start with an accredited accounting degree, then apply for a graduate role at an accounting firm or a state audit office. From there you complete the CA or CPA program over about three years while working, and register with ASIC if you want to sign statutory audit opinions.
Are external auditors in demand?
External auditors are currently in shortage nationally, and employment is projected to grow 15.9% over the decade to 2035. Openings are concentrated in accounting firms and public sector audit offices, which recruit through annual graduate intakes rather than advertising year-round.
Will AI replace external auditors?
Not the judgement, but it is already changing the testing. Analytics tools can now run a procedure over an entire ledger instead of a sample, and working paper platforms assemble much of the file as you go, so junior work is shifting from checking documents towards interpreting what the tools flag. The opinion still has to be formed and signed by a registered auditor.
What else can an external auditor do?
Internal audit is a common move and pays about the same, since the testing and controls work overlaps and needs only a short course to reframe it for management rather than shareholders. Forensic accounting is a smaller step, at $5,200 less and with evidence gathering carrying straight across. Auditors who stay and build client relationships can also move into financial control, which pays $41,600 more and puts you on the other side of the reporting line.
What is the difference between external and internal audit?
External auditors are independent of the organisation and report to shareholders and regulators through a formal opinion, while internal auditors are employed by the organisation and report to its management and board. The day-to-day testing looks similar, but who you answer to, and what you are allowed to do with what you find, is different.
