How to Choose an Auditor in Australia: ASIC Quality Standards and What to Look For in 2026

For Australian businesses, selecting the right auditor is one of the most consequential governance decisions a board or management team can make. Whether you are a large proprietary company with mandatory audit obligations, an SMSF trustee, a not-for-profit, or an ASX-listed entity, the quality of your audit directly affects your credibility with investors, regulators, and lenders. In 2026, with ASIC intensifying its surveillance program and expanding its focus to sustainability reporting, the stakes have never been higher.

Understanding the Australian Audit Landscape in 2026

Australia's audit profession is regulated by the Australian Securities and Investments Commission (ASIC), which registers company auditors and oversees audit quality through its annual inspection and surveillance programs. The Auditing and Assurance Standards Board (AUASB) sets the auditing standards that all registered auditors must follow, while the Financial Reporting Council (FRC) provides strategic oversight of the broader financial reporting framework.

ASIC's 2026–27 surveillance program signals a clear escalation in regulatory scrutiny. The regulator has committed to reviewing 25 audit files — up from 15 in prior years — using a risk-based and random selection approach. ASIC is specifically targeting audits where material corrections have occurred, where auditor independence concerns exist, and where data suggests a risk to audit quality.

For businesses choosing an auditor, this regulatory environment means that selecting a firm with a strong quality culture is not just good governance — it is essential risk management. An audit that fails ASIC's standards can trigger enforcement action, reputational damage, and costly remediation.

Who Needs an Auditor in Australia?

Audit obligations in Australia apply across a wide range of entity types. Understanding whether your organisation has a mandatory audit requirement is the first step.

• Large proprietary companies — Companies meeting two of three thresholds (consolidated revenue ≥ $50 million, gross assets ≥ $25 million, or 100+ employees) must have their financial reports audited under the Corporations Act 2001.
• ASX-listed entities — All listed companies must have audited annual financial statements. Those in the S&P All Ordinaries Index must also maintain an audit committee under ASX Listing Rule 12.7.
• Self-managed superannuation funds (SMSFs) — Every SMSF must be audited annually by an ASIC-registered SMSF auditor who is independent of the fund's trustees.
• Not-for-profits and charities — Entities registered with the Australian Charities and Not-for-profits Commission (ACNC) above certain revenue thresholds must have their financial statements reviewed or audited.
• Registrable superannuation entities (RSEs) — APRA-regulated superannuation funds face audit requirements under both the Corporations Act and APRA's prudential standards.
• Managed investment schemes — Registered schemes must have audited financial statements lodged with ASIC annually.

Even where an audit is not legally required, many businesses choose to engage an auditor voluntarily to satisfy lender covenants, attract investors, or strengthen internal controls.

Key Qualities to Look For in an Australian Auditor

Not all auditors are equal. When evaluating candidates, look beyond price and consider the following quality indicators.

ASIC Registration and Relevant Credentials

Any auditor signing off on a company's financial statements must be a registered company auditor (RCA) under the Corporations Act. For SMSF audits, the auditor must hold a separate ASIC registration as an approved SMSF auditor. Verify registration status directly on ASIC's public register before engaging any auditor.

Independence and Conflict-of-Interest Management

Auditor independence is the cornerstone of audit quality. ASIC's Report 817 — released in 2025 — found significant gaps in how some auditors demonstrate compliance with independence and conflict-of-interest obligations, noting a tendency toward narrow, tick-box approaches rather than genuine proactive assessment.

When assessing independence, consider whether the proposed auditor or their firm provides other services to your organisation (such as tax, consulting, or bookkeeping). The provision of non-audit services can create threats to independence that must be carefully managed under APES 110 (the Code of Ethics for Professional Accountants).

Industry and Sector Experience

Audit quality improves significantly when the auditor has deep experience in your industry. An auditor familiar with your sector will better understand the key risks, the relevant accounting standards, and the regulatory environment. For example, an SMSF auditor needs expertise in superannuation law, while an auditor of a mining company must understand asset impairment and site-restoration provisions.

Firm Quality Control Systems

Larger audit firms typically have more robust quality control systems, including engagement quality reviews, internal training programs, and peer review processes. However, smaller specialist firms can also deliver excellent quality in niche areas. Ask prospective auditors about their quality control procedures and whether they have been subject to any ASIC inspection findings or enforcement actions.

Communication and Responsiveness

A high-quality audit is a collaborative process. Your auditor should communicate clearly about the audit plan, key risk areas, and any issues identified during fieldwork. They should be accessible to your finance team and willing to explain their findings in plain language to the board or audit committee.

Common Mistakes When Choosing an Auditor

Many businesses make avoidable errors when selecting an auditor. Being aware of these pitfalls can save significant time, cost, and regulatory risk.

• Choosing on price alone — A low-cost audit may reflect insufficient time spent on fieldwork, which increases the risk of material misstatements going undetected. ASIC's inspection findings consistently show that inadequate audit procedures are a leading cause of audit deficiencies.
• Failing to verify ASIC registration — Engaging an unregistered auditor renders the audit invalid under the Corporations Act and can expose directors to personal liability.
• Ignoring independence threats — Allowing your auditor to also prepare your financial statements, provide bookkeeping services, or act as a tax agent creates self-review threats that can compromise audit independence.
• Not rotating auditors — While mandatory rotation applies only to listed entities (lead audit partner rotation every five years), voluntary rotation for other entities is considered best practice to maintain independence and bring fresh perspective.
• Leaving engagement too late — Quality auditors are in high demand, particularly at financial year-end. Engaging your auditor well in advance allows adequate planning time and reduces the risk of a rushed, lower-quality audit.
• Overlooking the audit committee's role — For entities with an audit committee, the committee should be actively involved in selecting, overseeing, and evaluating the external auditor — not simply rubber-stamping management's choice.

Australian Regulatory Context: ASIC, AUASB, and APRA

Understanding the regulatory framework helps businesses ask better questions and hold their auditors to account.

ASIC's Expanded Surveillance Program

ASIC's 2026–27 financial reporting and audit surveillance program focuses on several enduring risk areas: revenue recognition, asset impairment, financial instrument valuation, and provisions for decommissioning and site-restoration costs. ASIC is also overseeing the first wave of mandatory sustainability reporting under the Australian Sustainability Reporting Standards (ASRS), with Group 1 entities required to have their sustainability reports assured.

ASIC's enforcement toolkit includes the power to suspend or cancel auditor registrations, impose additional conditions, and seek court-enforceable undertakings. In 2024–25, ASIC took enforcement action against multiple auditors for failing to meet professional standards — a clear signal that the regulator is prepared to act.

AUASB Standards

The AUASB issues Australian Auditing Standards (ASAs), which are based on the International Standards on Auditing (ISAs) issued by the IAASB. All registered company auditors must comply with these standards. Key standards include ASA 200 (overall objectives), ASA 315 (identifying and assessing risks of material misstatement), and ASA 700 (forming an opinion and reporting on financial statements).

APRA's Role for Superannuation and Financial Institutions

For APRA-regulated entities — including banks, insurers, and superannuation funds — auditors must also comply with APRA's prudential standards and reporting requirements. APRA-regulated auditors face additional obligations around reporting to APRA directly in certain circumstances, including where they identify material breaches of prudential requirements.

Questions to Ask a Prospective Auditor

Before engaging an auditor, use these questions to assess their suitability for your organisation.

1. Are you registered with ASIC as a company auditor (or SMSF auditor)? Ask for your registration number so you can verify it independently.
2. Have you or your firm been subject to any ASIC inspection findings or enforcement actions in the past three years? A quality firm will be transparent about any findings and the remedial actions taken.
3. How do you manage independence threats, particularly if you provide other services to our organisation? Look for a structured, documented approach rather than a vague assurance.
4. What is your experience auditing entities in our industry or of our size? Relevant sector experience is a strong quality indicator.
5. Who will be the engagement partner and what is their involvement in the audit? Understand whether the partner will be actively involved or whether the work will be delegated entirely to junior staff.
6. What is your quality control process, including engagement quality reviews? Robust internal review processes are a hallmark of high-quality audit firms.
7. How do you communicate findings to the board or audit committee? Clear, timely communication is essential for effective governance.
8. What is your approach to sustainability assurance? For entities approaching mandatory sustainability reporting thresholds, this is increasingly important.
