What Is Professional Negligence Under Australian Law?

Professional negligence arises when a person or firm engaged in a skilled profession fails to exercise the standard of care that a reasonably competent practitioner in that field would have exercised, and that failure causes you a measurable loss. The concept derives from the common law duty of care established in Donoghue v Stevenson [1932] and refined extensively in Australian courts, including the landmark Tepko Pty Ltd v Water Board (2001) 206 CLR 1. Each Australian state and territory has its own civil liability legislation that modifies common law principles in specific ways — the Civil Liability Act 2002 (NSW), the Wrongs Act 1958 (Vic), and the Civil Liability Act 2003 (Qld) are the most commonly relevant statutes for professional negligence claims.

To establish professional negligence you must generally prove four elements:

• Duty of Care

  The professional owed you a legally recognised duty of care. This arises almost automatically from a retainer or engagement agreement with a solicitor, accountant, financial adviser, architect, migration agent or similar professional. In many cases the duty also extends to third parties who were foreseeably affected by the professional's work, such as beneficiaries under a negligently drafted will.

• Breach of that Duty

  The professional's conduct fell below the standard of a reasonably competent practitioner. Expert evidence is almost always required to establish the benchmark. For immigration practitioners, the benchmark is the standard of a competent registered migration agent or immigration lawyer as regulated by the Office of the Migration Agents Registration Authority.

• Causation

  The breach must have caused your loss — not a pre-existing problem or an independent intervening event. Courts apply the "but for" test: but for the professional's negligence, would the loss have occurred? In complex matters such as negligent litigation or negligent immigration advice, causation requires proving what the outcome would have been had the professional acted competently — a "trial within a trial" analysis.

• Loss or Damage

  You must have suffered quantifiable financial or personal loss as a direct result of the breach. Pure economic loss claims are well-established in Australian professional negligence law. In migration agent negligence claims, the loss can include visa application fees, relocation costs, lost employment income and the cost of remedial legal work to correct the error.

Types of Professional Negligence Claims in Australia

Almost any licensed or accredited professional can be the subject of a negligence claim. The most common categories Collins Quarters encounters include claims against solicitors, accountants, financial advisers, conveyancers, medical practitioners, architects, insurance brokers and migration agents and immigration lawyers. Each category involves different professional standards, regulatory regimes and typical loss patterns.

Limitation Periods for Professional Negligence Claims in Australia

Limitation periods are one of the most critical elements of any professional negligence claim, and ironically, one of the most common grounds for legal professional negligence itself — where a solicitor fails to commence proceedings within the applicable limitation period on behalf of their client, extinguishing the client's right to claim.

The limitation framework for professional negligence claims in Australia varies by state and territory. In Victoria, the Limitation of Actions Act 1958 imposes a general limitation period of six years from the date on which the cause of action accrued. In New South Wales, the Limitation Act 1969 imposes a six-year limitation period for actions founded on a cause of action in tort or contract. In Queensland, the Limitation of Actions Act 1974 applies a six-year general limitation period. Western Australia's Limitation Act 2005 similarly provides for a six-year general limitation period but contains specific provisions for professional negligence claims involving latent damage and long-stop limitation periods.

Importantly, the limitation period for professional negligence does not always commence from the date the negligent act occurred. In many cases, the limitation period runs from the date on which the plaintiff first suffered damage as a result of the negligent act, or from the date on which the plaintiff became aware (or ought reasonably to have become aware) that they had suffered loss attributable to the professional's negligence. This "discoverability" principle is particularly important in professional negligence claims where the effects of the negligent advice may not become apparent for years — for example, negligent wills and estates advice that only becomes apparent upon the testator's death, or negligent financial advice that only materialises when an investment fails years later.

For migration agent negligence claims, a separate and more urgent timeline also applies: the 21-day deadline for lodging an appeal at the Administrative Review Tribunal following a visa refusal. This immigration appeal deadline must be managed in parallel with the longer professional negligence limitation period. Collins Quarters' integrated dispute resolution and migration and global mobility practices allow us to manage both the negligence claim and the immigration matter concurrently.

How Professional Negligence Claims Are Resolved in Australia

Most professional negligence claims are defended vigorously by the professional's indemnity insurer. Understanding the resolution pathways is critical to managing your expectations and strategy.

Pre-litigation negotiation resolves a significant proportion of claims, particularly where expert evidence is clear and the professional indemnity insurer has a commercial interest in avoiding expensive litigation. Collins Quarters will prepare a detailed letter of claim setting out the duty, breach, causation and loss — designed to prompt a realistic settlement offer. Our corporate commercial practice supports pre-litigation strategy where the negligence occurred in the context of a business transaction such as a merger or acquisition.

Mediation is mandatory or strongly encouraged before trial in most Australian jurisdictions. Our dispute resolution lawyers are experienced mediators and advocates, and we achieve strong outcomes for clients at mediation. Read more about our approach to cross-border commercial dispute resolution.

Litigation in the Supreme or Federal Court is sometimes unavoidable — particularly in high-value claims or where the insurer denies liability entirely. Our litigation team has the depth and experience to take complex professional negligence matters through to trial if necessary. For claims with a cross-border dimension — for example, where the negligent professional provided advice on an investment and market entry transaction involving Indian and Australian parties — our India practice coordinates with our Australian dispute resolution practice to manage the claim across jurisdictions.

What Compensation You Can Recover in a Professional Negligence Claim

In a successful professional negligence claim in Australia, the measure of damages is typically the difference between your actual position and the position you would have been in had the professional performed their duty correctly. This is known as the "loss of chance" or "position comparison" methodology and is the standard approach in Australian tort law for professional negligence.

The heads of recoverable loss include the direct financial loss caused by the negligent advice or service, consequential losses that flow naturally from the error, interest on the amounts lost from the date of loss to the date of judgment, and in some cases the costs of the litigation itself. In migration agent negligence claims, recoverable losses commonly include visa application fees paid to the Department of Home Affairs that are lost upon refusal, fees paid to the negligent migration agent, the cost of engaging a new immigration lawyer to lodge a fresh application or pursue an ART review, lost employment income during the period when the visa was refused and the applicant was unable to work, relocation costs if the applicant was forced to leave Australia as a result of the refusal, and consequential losses such as lost business opportunities, broken employer sponsorship arrangements or forfeited property deposits where FIRB approval was dependent on visa status.

For conveyancer negligence claims, the loss is typically the difference between the price paid for the property and its actual value given the undisclosed defect, or the additional cost of rectification. For financial adviser negligence, the loss is typically the diminution in the client's portfolio value compared to what a competent adviser would have achieved. In family law solicitor negligence claims, the loss is the difference between the property settlement actually achieved and the settlement that would have been achieved but for the negligence.

Professional Negligence Involving Immigration Lawyers and Migration Agents in Australia

One of the fastest-growing categories of professional negligence claims in Australia involves migration agents and immigration lawyers. Given the life-changing consequences of a visa refusal, cancellation, or incorrect advice, these claims carry enormous personal and financial stakes. Migration agents are regulated by the Office of the Migration Agents Registration Authority and must comply with the Code of Conduct for registered migration agents. Immigration lawyers who are also admitted legal practitioners are subject to the professional conduct rules of their state or territory legal profession regulatory body in addition to OMARA obligations.

Common grounds for migration agent and immigration lawyer negligence that Collins Quarters has encountered include failure to lodge a visa application within the applicable deadline, resulting in the applicant becoming unlawful in Australia, advising a client to apply for the wrong visa subclass when a more appropriate pathway was available, omitting critical supporting documents such as skills assessment outcomes, English language test results or employer sponsorship documentation, failing to advise on the section 48 bar which prevents certain applicants from making further onshore visa applications after a refusal, providing negligent advice on the genuineness of a partner relationship for a partner visa application, and failing to advise an employer on their sponsorship compliance obligations under the Migration Act and the Fair Work Act.

If a migration agent or immigration lawyer in Melbourne, immigration lawyer in Sydney, or immigration lawyer in Brisbane caused your visa to be refused or cancelled through negligent advice or procedural error, you may have a claim — and you may also be able to seek a merits review at the Administrative Review Tribunal. Our team can advise on both the negligence claim and the immigration pathway. See our guide on how to appeal a visa refusal in Australia and our comprehensive guide on immigration lawyers across Australia.

We also assist clients whose employer-sponsored visa applications were mishandled. If your employer or their adviser failed to comply with sponsorship obligations under the Migration Act, causing your subclass 482, subclass 494 or subclass 186 application to be refused, you should speak with our team urgently. Our employer sponsorship 482 visa complete guide explains the obligations that commonly give rise to negligence claims.

For clients who wish to understand the professional standards framework that applies to migration agents, our guides on how to become a migration agent in Australia and immigration attorney vs immigration lawyer in Australia explain the registration requirements, professional indemnity insurance obligations, and code of conduct that define the benchmark standard of care in migration agent negligence claims. Understanding attorney-client privilege in an immigration context is also critical, as the scope of privilege differs between communications with qualified lawyers and those with migration agents who are not admitted legal practitioners.

Conveyancer and Property Lawyer Negligence in Australia

Conveyancer and property lawyer negligence is one of the most financially damaging categories of professional negligence because it typically involves the largest single transaction most individuals or businesses will undertake — the purchase or sale of real property. The duty of care owed by a conveyancer or property solicitor to their client encompasses conducting proper title searches, identifying and advising on special conditions, ensuring compliance with stamp duty and land tax obligations, managing the settlement process competently, and advising on any restrictions, caveats, easements or encumbrances affecting the property.

Common grounds for conveyancer negligence claims that Collins Quarters' property and conveyancing practice encounters include failure to identify a defect in title or an unregistered interest affecting the property, failure to conduct or properly review zoning and planning searches, incorrect advice on stamp duty concessions resulting in a clawback or penalty, failure to manage settlement deadlines causing financial loss through late settlement penalties or contract rescission, and errors in contract preparation that expose the client to terms they did not agree to.

For foreign investors buying property in Australia, conveyancer negligence can have additional consequences including FIRB compliance failures where the conveyancer failed to advise on the requirement to obtain FIRB approval before exchange of contracts, or incorrectly advised on the nationality and visa status tests that determine FIRB obligation. Our FIRB national interest test guide explains the compliance framework that conveyancers must understand when acting for foreign purchasers. Our property investment guide for foreign buyers provides further context on the legal obligations that arise in these transactions.

Collins Quarters' property negligence claims are managed by our dispute resolution practice in coordination with our property and conveyancing practice, ensuring that we apply deep subject matter expertise to the assessment of whether the conveyancer's conduct fell below the required standard. Our city-specific Melbourne property lawyer, Sydney property lawyer, Brisbane property lawyer and Perth property lawyer teams can advise on conveyancer negligence claims specific to their jurisdictions.

Financial Adviser and Accountant Negligence in Australia

Financial adviser and accountant negligence claims are among the most complex professional negligence matters in Australian law. Financial advisers operating under an Australian Financial Services Licence have a best-interests duty under section 961B of the Corporations Act 2001 (Cth), which requires the adviser to act in the best interests of the client in relation to the advice provided. Breach of this statutory duty can give rise to both a professional negligence claim at common law and a statutory compensation claim under the Corporations Act.

Common grounds for financial adviser negligence include recommending investments that were unsuitable for the client's risk profile, investment horizon or stated objectives, failure to diversify a portfolio resulting in concentrated exposure to a single asset class or sector, failure to disclose conflicts of interest including commission payments, and churning of a portfolio to generate commissions at the expense of the client's returns.

Accountant negligence claims frequently arise from incorrect tax advice resulting in ATO penalties, incorrect structuring of business entities resulting in unintended tax liabilities, errors in financial statements relied upon by third parties such as purchasers in a business sale or lenders assessing a loan application, and failure to advise on GST, payroll tax or superannuation obligations. For businesses involved in mergers and acquisitions, negligent accounting advice during the due diligence process can result in significant post-acquisition losses. See our guide on M&A trends in 2026 for context on the complexity of these transactions.

For business migration applicants whose accountant provided negligent net asset or business turnover calculations in support of a subclass 188A or 188B visa application, the error can result in visa refusal and the loss of the entire migration pathway. Collins Quarters' integrated migration and global mobility and dispute resolution practices allow us to pursue the accountant negligence claim while simultaneously assisting with a fresh visa application or ART review. Our guides on business migration for entrepreneurs and how entrepreneurs can achieve business migration to Australia explain the financial documentation requirements that accountants must prepare competently.

Family Law Solicitor Negligence in Australia

Negligent family law advice can have catastrophic and often irreversible consequences for property settlements, parenting arrangements and spousal maintenance outcomes. The family law system in Australia operates under the Family Law Act 1975 (Cth) and involves complex valuations of property pools, superannuation interests, trusts and corporate structures, as well as sensitive parenting matters where the best interests of the child are the paramount consideration.

Common grounds for family law solicitor negligence include failure to identify and properly value all assets in the property pool, incorrect advice on the treatment of pre-relationship assets or inheritances, failure to obtain proper valuations of businesses, real property or superannuation interests, negligent advice on consent order terms that fail to protect the client's interests, and failure to advise on the tax consequences of a proposed property settlement.

Collins Quarters' family law practice works alongside our dispute resolution practice to assess whether a previous family law solicitor's conduct fell below the required standard. Our Melbourne family lawyers, Sydney family lawyers, Brisbane family lawyers and Perth family lawyers regularly encounter cases where previous solicitors performed poorly, particularly in matters involving cross-border elements where the family law implications intersect with immigration status. For international couples, see our guide on family law considerations for international couples in Australia and our guide to family law lawyers in Parramatta and Western Sydney. For an alternative family law firm in Melbourne, see our review of Coote Family Lawyers as a best alternative family law firm in Melbourne.

Wills and Estates Solicitor Negligence in Australia

Negligent drafting of a will or estate plan can cause an entire testamentary scheme to fail, resulting in assets being distributed contrary to the deceased's wishes, unnecessary tax obligations and expensive estate litigation. Wills and estates negligence claims in Australia are notable because the loss is often suffered by a beneficiary who was not the solicitor's direct client — the testator was the client — giving rise to complex questions about to whom the duty of care was owed.

Australian courts have recognised that a solicitor who drafts a will owes a duty of care not only to the testator but also to intended beneficiaries whose interests were foreseeably affected by the solicitor's negligence. This principle, established in cases such as Hill v Van Erp (1997) 188 CLR 159, means that a beneficiary who was disinherited or received less than intended as a result of a drafting error can bring a professional negligence claim against the solicitor.

Common grounds for wills and estates solicitor negligence include failing to ensure the will was executed with proper formalities, failing to include a valid residuary clause, failing to properly identify and describe beneficiaries or assets, failing to advise on the interaction between the will and binding death benefit nominations on superannuation, and failing to advise on cross-border estate planning for clients with assets in multiple jurisdictions.

Collins Quarters' wills and estates practice has specialist experience in cross-border estate planning for clients with assets in India and Australia. Our Melbourne wills and estates lawyers and Sydney wills and estates lawyers assist beneficiaries in assessing whether a professional negligence claim lies against the original drafter. For clients with cross-border assets, our guide on wills and estates planning for cross-border assets explains the complexities that a competent solicitor should have addressed.
