Proximity in negligence law describes the closeness of the relationship between two parties — and whether that relationship is sufficiently close to impose a legal duty of care. Australian courts use proximity to assess whether a professional’s conduct was capable of affecting an identifiable person or class of persons. Without a recognised proximity relationship, a duty of care cannot be established, and a negligence claim cannot proceed.
To succeed in a professional negligence claim in Australia, a claimant must establish three things: that the professional owed them a duty of care, that the professional breached that duty, and that the breach caused measurable loss or damage.
Proximity sits within the first element — duty of care. It is not a separate test that operates independently. Instead, it is one of several factors Australian courts consider when deciding whether a duty should be recognised in a particular situation.
Following the High Court’s decision in Perre v Apand Pty Ltd [1999] HCA 36, Australian courts moved away from treating proximity as a standalone determinant of duty of care. The preferred approach became an assessment of “salient features” — a broader inquiry into whether, in all the circumstances, it is appropriate to impose a duty. Proximity remains a relevant consideration within that inquiry, but it no longer carries the same weight it once did as a threshold question.
For most professional negligence claims — where there is a direct engagement between a professional and a client — proximity is rarely in dispute. It becomes contested in cases involving third parties, pure economic loss, or situations where no formal engagement existed.
The concept of proximity in negligence traces back to Lord Atkin’s neighbour principle in Donoghue v Stevenson [1932] AC 562. Lord Atkin asked who, in law, is my neighbour — and answered that a person must take reasonable care to avoid acts or omissions that could reasonably be expected to injure those so closely and directly affected that they ought to have them in contemplation.
Australian courts adopted this principle but refined it significantly over the following decades. In Jaensch v Coffey (1984) 155 CLR 549, the High Court treated proximity as a central concept in defining duty of care. For a period, it seemed proximity might become the unifying principle of Australian negligence law.
That approach was reconsidered. In Sullivan v Moody (2001) 207 CLR 562, the High Court stepped back from proximity as a standalone organising principle. The Court held that the appropriate question is not simply whether the parties are proximate, but whether the relevant salient features of the relationship — including vulnerability, reliance, and the nature of the loss — justify imposing a duty. Proximity is a useful concept, but it does not on its own answer the question.
For most people reading this, the practical question is simple: did the professional who harmed me owe me a duty of care? In the majority of direct professional relationships, the answer is yes — and proximity is not in dispute. Here is how it plays out across different scenarios:
The last two examples illustrate why specialist legal advice matters. Where proximity is clear, a claim can move quickly to the question of breach. Where it is contested, more detailed legal analysis is required before a claim is viable.
Rogers v Whitaker
(1992) 175 CLR 479 — High Court of Australia
Facts: A patient suffered serious eye complications following surgery and alleged her surgeon failed to warn her of a material risk before she consented to the procedure.
Principle: The High Court held that a doctor owes a duty to warn patients of material risks, arising from the proximity of the doctor-patient relationship itself. Proximity here is defined by the clinical relationship — not merely by the technical quality of the treatment delivered.
Relevance today: The leading authority on the scope of a doctor’s duty of care in Australia. Relevant to any claim involving failure to advise, failure to warn, or inadequate disclosure in a medical setting.
Perre v Apand Pty Ltd
[1999] HCA 36 — High Court of Australia
Facts: A seed supplier provided contaminated potato seed that triggered a disease outbreak. Neighbouring farmers with no direct relationship to the supplier suffered pure economic loss when their crops were quarantined as a preventive measure.
Principle: The High Court found a duty of care existed but declined to ground it solely in proximity, instead applying a salient features analysis. Proximity was one factor among several — alongside the vulnerability of the plaintiffs and the defendant’s knowledge of likely impact.
Relevance today: This decision fundamentally reshaped Australian negligence law by confirming the departure from proximity as the primary test and establishing the salient features framework used by courts today.
Sullivan v Moody
(2001) 207 CLR 562 — High Court of Australia
Facts: Medical officers and welfare investigators assessing children for possible abuse were sued by parents who claimed the investigation process itself had caused them harm.
Principle: The High Court held that proximity alone was insufficient to establish a duty of care. The court asked whether the salient features of the relationship — including the purpose of the investigation and the potential for conflicting duties — justified imposing liability.
Relevance today: The case that confirmed Australian law’s departure from proximity as a standalone test. Directly relevant when assessing duty of care in complex professional relationships involving multiple obligations or competing interests.
Esanda Finance Corporation Ltd v Peat Marwick Hungerfords
(1997) 188 CLR 241 — High Court of Australia
Facts: Esanda made lending decisions in reliance on audited financial statements prepared by Peat Marwick. When those statements proved materially misleading, Esanda suffered significant loss.
Principle: The High Court held that mere knowledge that financial statements would be available to third parties was not sufficient to establish the proximity required for a duty of care. Esanda was required to show that Peat Marwick knew its work would be relied upon by a specific, identifiable class.
Relevance today: A key authority limiting auditor and professional liability to third parties in Australian law. Relevant to any claim where the claimant did not directly engage the professional whose work they relied upon.
If you engaged a professional directly — under a retainer, service agreement, advisory contract, or clinical relationship — proximity is almost certainly established. The focus of your claim will be on whether the professional’s conduct fell below the required standard of care.
Where proximity becomes a live issue is in claims involving third-party reliance: situations where you suffered loss because of a professional’s work, but you were not the person who engaged them. These cases require careful legal analysis — but they are not without hope. Australian courts have found duties of care to third parties in appropriate circumstances.
The question is always whether, looked at as a whole, the relationship between you and the professional had the features that warrant imposing a legal obligation. A specialist professional negligence lawyer can assess this quickly and give you a clear view of whether your situation is likely to support a claim. Understanding causation is the next step once duty of care is confirmed.
If you are unsure whether your situation involves a recognised proximity relationship, the most practical step is a free case evaluation with a professional negligence specialist.
In most Australian states, professional negligence claims must be commenced within three years of the date you became aware — or should reasonably have become aware — of the negligence. This period varies by state and claim type. Missing this deadline can permanently extinguish your right to claim.
If you are unsure whether your limitation period is still open, contact our team for a free assessment as soon as possible.
Proximity can be a nuanced question — but the underlying issue is straightforward: did a professional owe you a duty of care, and did they fail you? Our specialist professional negligence lawyers can assess your situation quickly and clearly, at no cost and no obligation. If you have a viable claim, we act on a no-win, no-fee basis.
Proximity describes the closeness of the relationship between a claimant and a professional — specifically, whether that relationship is sufficiently close to give rise to a duty of care. In modern Australian law, proximity is assessed as part of a broader inquiry into the salient features of the relationship, rather than as a standalone threshold test. Courts consider factors including foreseeability, vulnerability, reliance, and the nature of the loss suffered.
Not as a standalone requirement. Since Sullivan v Moody (2001) 207 CLR 562, Australian courts have moved away from treating proximity as the primary determinant of duty of care. Courts now assess the salient features of the relationship as a whole. Proximity remains a relevant consideration within that analysis, but it does not on its own determine whether a duty is owed.
Yes — proximity can still be relevant even where no direct contract existed. Courts will consider whether the professional knew, or ought reasonably to have known, that you would rely on their work, and whether it is appropriate in all the circumstances to impose a duty. Third-party proximity claims are more complex and require specialist legal assessment, but they are not without precedent in Australian law.
Duty of care is the legal obligation itself. Proximity is one of the factors courts consider when deciding whether that obligation should be recognised in a particular situation. Think of proximity as part of the foundation — it helps determine whether a duty arises, but it does not define the full scope of what that duty requires. Once a duty is established, the standard of care and causation become the focus.
Possibly — depending on your situation. Where proximity is contested, a specialist lawyer will analyse the salient features of the relationship to assess whether a duty of care can be established. An unclear proximity situation does not automatically rule out a claim. The most practical step is a free case evaluation so you can understand your position clearly and without obligation.
