Most people who contact us haven’t had a physical injury. They’ve lost money. Retirement savings wiped out by bad financial advice. A business deal gone wrong because a solicitor missed something critical. A tax position that collapsed because an accountant got it wrong.
Pure financial loss — no broken bones, no damaged property — just the quiet devastation of watching what you’d worked for disappear because someone who knew better failed to do their job properly.
For a long time, Australian law was uncomfortable with these kinds of claims. If you weren’t physically hurt, could you really sue someone for negligence? Perre v Apand Pty Ltd (1999) 198 CLR 180 is one of the High Court decisions that changed that conversation — and its principles reach well beyond the farmland where it started.
| Case name | Perre v Apand Pty Ltd |
| Citation | (1999) 198 CLR 180; [1999] HCA 36 |
| Court | High Court of Australia |
| Year | 1999 |
| Decision | Apand owed a duty of care to neighbouring farmers who suffered pure economic loss after Apand’s negligent supply of infected seed potatoes triggered quarantine restrictions that shut them out of their primary market. |
| Key principle | A duty of care can extend to pure economic loss where the defendant knew of the risk to an ascertainable, vulnerable class of plaintiffs — and those plaintiffs had no reasonable way to protect themselves. |
Apand Pty Ltd supplied seed potatoes to a farm operated by the Sparnon family near Paringa in South Australia. The seed stock was infected with bacterial wilt — a notifiable disease caused by Ralstonia solanacearum.
The infection spread through the Sparnons’ crop. That triggered Western Australia’s strict quarantine regulations, which prohibited the export of potatoes from any property situated within 20 kilometres of a confirmed infection.
The Perre family were potato farmers. Their land fell within that quarantine zone. Their own crops were clean — not a trace of bacterial wilt. But it didn’t matter. Under WA quarantine law, they couldn’t export to their primary market regardless.
The financial loss was significant. And it had nothing to do with anything the Perres had done.
There was no contract between the Perres and Apand. The Perres had never dealt with Apand. Their land wasn’t damaged. Their crops weren’t infected. By traditional legal thinking, they had no claim. They brought one anyway.
The High Court held that Apand owed the Perre family — and other neighbouring farmers in the same position — a duty of care in negligence. Apand was liable for the pure economic loss the Perres suffered.
That was not a given. Pure economic loss claims had always been treated with caution by Australian courts. The concern was always the same: open the floodgates too wide and anyone who suffers financially because of someone else’s negligence could come knocking.
The majority in Perre v Apand drew a careful line. The duty didn’t extend to the whole world. It extended to this particular group of farmers — an ascertainable class who were foreseeably and directly affected by Apand’s negligence — because of two things working together: what Apand knew, and how vulnerable those farmers were.
Pure economic loss is financial loss that occurs without any physical injury to a person or physical damage to property. It’s the loss you suffer in your bank account — not in your body or your building.
Australian courts have historically been more willing to compensate for physical harm than for financial loss alone. The worry is that financial losses can ripple outward almost indefinitely, and a rule that everyone affected by a negligent act can claim would create an unworkable situation for defendants — and for courts.
Perre v Apand didn’t throw open the doors. But it confirmed that pure economic loss can be compensable in negligence where the right conditions are present.
Vulnerability is at the heart of this case. The High Court reasoned that the Perres could not protect themselves from Apand’s conduct. They didn’t know Apand. They had no relationship with Apand. They had no way of knowing what seed stock Apand was supplying to a neighbouring farm, or what the condition of that stock was.
The quarantine regulations that ultimately caused their loss were triggered by something entirely outside their control and entirely inside Apand’s. They were, in the relevant legal sense, vulnerable — exposed to a risk they had no practical means of avoiding.
That vulnerability is a key limiting principle. Not every business that loses money when someone else is negligent can claim. But where a plaintiff is genuinely unable to protect themselves from the risk created by the defendant’s conduct, that factor weighs heavily toward recognising a duty of care.
The other side of the equation is the defendant’s knowledge. Apand knew — or should have known — that bacterial wilt was a notifiable disease. Apand knew, or should have known, that WA quarantine law imposed a zone-based export ban. And Apand knew, or should have known, that other potato farmers in the vicinity of any infected property would be directly affected if an infection occurred.
The class of people at risk wasn’t vague or unlimited. It was specific and foreseeable — farmers whose land happened to fall within the quarantine zone around any property Apand supplied. That specificity mattered. Knowledge of a real, identifiable risk to a real, identifiable group sits differently to a generalised possibility that someone, somewhere, might lose money.
One of the reasons Perre v Apand didn’t open the floodgates is that the High Court paid careful attention to who was affected and how.
The Perres weren’t simply members of the public who happened to feel the downstream financial effects of Apand’s negligence. They were a defined and ascertainable class — neighbouring farmers whose ability to export depended directly on what happened on adjacent land. Their loss was not speculative or indirect. It flowed directly from Apand’s conduct in a way that was foreseeable, specific, and significant.
Courts drawing on Perre v Apand continue to ask: was the plaintiff an identifiable, foreseeable victim? Or are they simply one of many people whose finances were touched at the edges by someone else’s mistake?
The Perres were potato farmers. Most people reading this are not. But the principles from their case are applied routinely to professional negligence claims — particularly where a client suffers financial loss rather than physical harm.
Consider these situations:
A financial adviser recommends unsuitable investments. The client has limited financial sophistication, limited alternative options, and is entirely reliant on the adviser’s expertise. When the investment collapses, the client is left with losses they had no way of anticipating and no way of preventing. They were vulnerable. The adviser knew — or should have known — what the risks were. Perre v Apand’s framework is directly relevant.
An accountant provides negligent tax advice. The client follows that advice in good faith and ends up facing ATO penalties and interest on a position that should never have been taken. The loss is purely financial. The client couldn’t have known the advice was wrong — that’s precisely why they hired an expert. Vulnerability, plus the professional’s knowledge of the client’s circumstances, brings this squarely within the principles the High Court developed.
A business client signs a contract in reliance on their solicitor’s review. The solicitor misses a clause that later costs the client significantly. No physical harm. Pure economic loss. But the solicitor knew what they were reviewing, knew who their client was, and knew the stakes involved.
None of these situations are identical to Perre v Apand. But the underlying question is the same: did the defendant know enough about the plaintiff’s situation to understand that a failure on their part would likely cause financial harm — and was the plaintiff in a position where they couldn’t reasonably protect themselves from that risk?
Where the answer to both questions is yes, the path toward a negligence claim is open.
It is worth noting that Perre v Apand expanded the law — it didn’t create a blanket right to claim for any financial loss caused by anyone’s carelessness. Each case turns on its specific facts. But the case confirmed that Australian law is not closed to pure economic loss claims, and that financial harm caused by a professional who should have known better can absolutely found a negligence action.
Professional negligence claims are subject to strict limitation periods — generally 3 years from the date you became aware (or reasonably should have become aware) of the negligence, though this varies by state. Missing this deadline can permanently extinguish your right to claim.

The High Court held that Apand Pty Ltd owed a duty of care to neighbouring potato farmers who suffered pure economic loss after Apand’s negligent supply of infected seed stock triggered quarantine restrictions that cut them off from their main market. The farmers’ crops weren’t infected — but they lost their export income because of what happened on an adjacent property. The Court found that Apand’s knowledge of the quarantine rules, combined with the farmers’ vulnerability to the consequences, was sufficient to establish a duty of care.
Pure economic loss is financial loss that occurs without any accompanying physical injury or property damage. It’s the kind of loss you experience entirely in your bank account — money lost, income foregone, a business opportunity destroyed. Australian courts have historically been cautious about allowing pure economic loss claims because financial harm can ripple broadly and be difficult to contain. Perre v Apand confirmed that these claims are not automatically excluded, but they require specific conditions — particularly that the defendant knew of the risk and the plaintiff was vulnerable to it.
In certain circumstances, yes. Perre v Apand confirmed that Australian negligence law is not limited to cases involving physical harm. Where a professional owed you a duty of care, breached that duty, and caused you measurable financial loss — and you were in a position where you couldn’t reasonably protect yourself from the consequences of their failure — a negligence claim may be available. Whether that applies to your specific situation depends on the facts. A free case evaluation is the best way to find out.
