Medical malpractice cases are among the most complex and emotionally challenging legal matters in Australia’s personal injury landscape. When patients seek medical care, they place their trust in healthcare professionals to provide treatment that meets established standards. However, medical errors can occur, and when these mistakes result from negligence or intentional misconduct, they may qualify as medical malpractice.

For Australians who have suffered harm due to medical malpractice, understanding the legal framework surrounding these cases is essential. This guide provides comprehensive information on medical malpractice claims in Australia, including what constitutes malpractice, common examples and how to prove such claims.

If you or a loved one has experienced harm from suspected medical malpractice, this resource will help you navigate the potential pathways to seeking compensation and justice.

What constitutes medical malpractice in Australia?

Medical malpractice in Australia is governed by specific legal principles that distinguish it from other forms of professional negligence. Understanding this distinction is important for anyone considering a claim.

Medical malpractice vs. Medical negligence

Although the terms ‘medical malpractice’ and ‘medical negligence’ are often used interchangeably, they hold important legal differences in Australia.

  • Medical negligence is when a healthcare provider fails to meet the accepted standard of care, resulting in harm to a patient. This can happen due to errors of omission or commission and does not necessarily involve intentional wrongdoing.
  • Medical malpractice, in contrast, typically involves a more severe breach of professional duty. It often suggests that the healthcare provider acted with knowledge or awareness of potential risks but chose to proceed regardless. In Australia, medical malpractice claims usually require proof that the healthcare provider knowingly deviated from acceptable standards, rather than simply making a mistake.

This distinction is significant, as proving medical malpractice typically involves demonstrating that the provider’s actions went beyond negligence and highlights a deliberate departure from established practices.

Legal framework for medical malpractice in Australia

In Australia, medical malpractice claims are governed by:

1. Civil liability acts

Each Australian state and territory has enacted its own legislation governing medical negligence and malpractice claims. For example, New South Wales operates under the Civil Liability Act 2002 (NSW), while Victoria follows the Wrongs Act 1958 (VIC). These statutes outline the procedures and limitations for pursuing such claims.

2. Common law principles

Australian courts have established precedents that define the duty of care owed by healthcare providers to patients. These common law principles are integral to understanding and proving medical negligence cases.

3. The Australian Open Disclosure Framework

This national Australian Open Disclosure Framework encourages healthcare providers to be open and transparent about adverse events, which can impact how medical malpractice cases proceed. It emphasises open and timely communication, acknowledgment, apology or expression of regret, and support for both patients and healthcare staff.

In the context of a medical malpractice claim, the Open Disclosure Framework can be pivotal. It encourages healthcare providers to disclose errors, which may provide key evidence such as admissions of fault or acknowledgment of deviations from accepted standards. This transparency can strengthen your (the plaintiff’s) case.

Elements required to prove medical malpractice

To pursue a medical malpractice claim in Australia, claimants must prove four key elements, all of which are rooted in common law principles:

1. Duty of care

The healthcare provider had a duty to care for the patient, which is usually clear in doctor-patient relationships.

2. Breach of duty

The healthcare provider failed to meet the standard of care expected. This is judged by comparing their actions to what a reasonable professional would have done in the same situation.

3. Causation

The provider’s breach of duty directly caused the patient’s harm. This means proving that the injury would not have happened ‘but for’ the provider’s actions.

4. Damages

The patient experienced harm or loss as a result of the breach, which could include physical injuries, emotional distress, financial losses, or reduced quality of life.

Examples of medical malpractice

Medical malpractice can happen in any healthcare setting and involve practitioners across all specialties.

The following examples highlight common scenarios that have led to successful malpractice claims in Australia.

Surgical errors

Surgical malpractice remains one of the most visible forms of medical error and can include:

  • Wrong-site surgery: Operating on the incorrect body part or the wrong patient entirely
  • Retained surgical instruments: Leaving surgical tools, sponges, or other materials inside a patient
  • Unnecessary surgery: Performing procedures that were not medically indicated
  • Surgical technique errors: Making mistakes during the operation that cause additional injuries.

Common case

Bile Duct Injury (BDI) during gallbladder surgery is a common cause of medical malpractice claims.

According to one medico-legal study, laparoscopic cholecystectomy (a widely performed procedure for gallbladder removal) carries a two to three times higher risk of BDI compared to open cholecystectomy, with an estimated risk of around 0.5%. BDI can result in severe complications, including long-term health issues or even death.

Because of this, BDIs are often a key factor in medical malpractice claims in Australia. Patients frequently pursue lawsuits due to the significant impact on their health and the need for extensive corrective surgeries.

Misdiagnosis or delayed diagnosis

Failure to correctly diagnose a condition, especially when symptoms are present and observable, is a significant category of medical malpractice claims in Australia. These cases often involve serious errors where a healthcare provider fails to meet the accepted standard of care, leading to severe consequences for the patient.

Delayed diagnosis can include:

  • Cancer misdiagnosis: Failing to identify cancer despite symptomatic presentation, leading to delayed treatment and poorer prognosis
  • Heart attack or stroke misdiagnosis: Mistaking life-threatening cardiac or neurological events for less serious conditions
  • Infection misdiagnosis: Failing to recognise or properly treat serious infections, leading to sepsis or other complications.

Case example: Delayed diagnosis of bowel cancer

In 2019, our client began experiencing abdominal pain and diarrhoea. Despite these symptoms, he was diagnosed with diverticulitis and treated with medication, but his condition worsened. By 2021, after experiencing significant GI bleeding, a CT scan revealed primary bowel cancer with metastasis. By this time, the cancer had become terminal, having spread to the lungs, and requiring extensive treatment.

Experts in the case believed there was a clear breach of duty in the healthcare provider’s failure to order a colonoscopy and to investigate the symptoms earlier. If diagnosed sooner, the cancer would have been potentially curable. Due to the delayed diagnosis, the client suffered a reduced life expectancy, severe health deterioration, and significant financial loss.

As a result of this malpractice, our client received a settlement of $300,000, inclusive of legal costs.

Medication errors

Medication-related malpractice can occur at various stages of treatment, including:

  • Prescription errors: Prescribing the wrong medication or incorrect dosage
  • Administration errors: Giving the wrong medication or incorrect dose to a patient
  • Monitoring failures: Not adequately monitoring patients for known medication side effects
  • Contraindication oversight: Prescribing medications that interact negatively with a patient’s other medications or conditions.

Case example

Vanessa Anderson died in 2008 after being given the wrong medication following treatment for a head injury. A coronial inquest revealed multiple failures in care and communication (including a doctor misreading her chart), which contributed to the medication error.

This case led to significant reforms in the New South Wales healthcare system, improving medication safety and communication protocols. It serves as a clear example of how individual cases can drive broader system-wide changes in patient care.

Birth injuries

Obstetric malpractice can result in particularly devastating outcomes.

Birth injuries can occur due to:

  • Failure to monitor fetal distress: Not responding appropriately to signs of fetal distress during labour
  • Mismanagement of delivery complications: Inadequate handling of situations like shoulder dystocia or umbilical cord issues
  • Delayed cesarean section: Failing to perform a timely C-section when medically necessary
  • Improper use of delivery tools: Causing injury through incorrect use of forceps or vacuum extractors.

Case example

In 2019, the Western Australia District Court awarded $2,190,000 in damages to a family after their child suffered brain injuries during birth, resulting in lifelong developmental and cognitive impairments. The negligence occurred when forceps were improperly used during delivery, despite the mother’s pelvis being too narrow for the head and the baby’s position requiring specialist intervention in a theatre. Evidence showed that the use of forceps in this situation was inappropriate and contributed to the child’s severe injuries.

Anaesthesia errors

Mistakes in anaesthesia can result in serious and sometimes life-threatening consequences.

Common anaesthesia errors include:

  • Dosage errors: Administering too much or too little anaesthesia
  • Intubation errors: Mistakes during the intubation process causing oxygen deprivation
  • Monitoring failures: Not properly monitoring vital signs during procedures
  • Failure to recognise complications: Missing signs of adverse reactions to anaesthesia.

Case incidence

A study published in 2009 highlighted the severe impact of awareness during surgery, which is a significant concern for both anaesthetists and patients. These incidents account for around 2% of all legal claims made against anaesthetists.

Patients who experience intraoperative awareness often describe the ordeal as deeply traumatising. The combination of pain, anxiety, and the inability to move due to muscle paralysis can lead to lasting psychological effects, including post-traumatic stress disorder (PTSD). Because of this, many patients require ongoing psychiatric support to manage the emotional and mental toll of an anaesthesia error.

Failure to obtain informed consent

Healthcare providers must ensure patients fully understand the risks and alternatives associated with a procedure.

Key issues include:

  • Inadequate disclosure of risks: Failure to inform patients about significant or material risks associated with a procedure, even if the risks are rare
  • Failure to discuss alternatives: Healthcare providers must present reasonable alternative treatment options to patients. Failing to discuss these alternatives may violate the duty to inform, especially if an alternative treatment would have been a safer or more effective choice for the patient
  • Language or comprehension barriers: Not ensuring patients with language difficulties or cognitive limitations understand the consent process. This may involve using interpreters or providing clear, accessible explanations tailored to the patient’s level of comprehension. Failing to address these barriers can result in patients giving consent without a proper understanding of the procedure.

Case example

In the landmark Australian case Rogers v Whitaker (1992), the High Court held surgeon Dr. Rogers liable for failing to disclose a small but significant risk that led to serious harm. Mrs. Whitaker underwent eye surgery with Dr. Rogers, who neglected to inform her of the rare but serious risk of sympathetic ophthalmia. Consequently, she developed the condition and lost vision in both eyes.

Although the risk was low, the Court ruled Dr. Rogers at fault, establishing that healthcare providers must disclose all material risks that a reasonable person would consider significant when deciding whether to proceed with treatment. This case solidified the principle of informed consent in Australian medical law.

The incidence of medical malpractice in Australia

To understand the broader context of medical malpractice in Australia, it’s important to consider the scale and frequency of medical errors.

These statistics highlight the significant impact on both patients and the healthcare system:

High-risk specialties

Certain medical specialties are more prone to malpractice claims due to the complexity, high stakes, and volume of procedures or patients involved. These specialties consistently account for a higher proportion of claims.

High-risk areas include:

  1. Obstetrics and gynaecology: Birth-related claims often involve significant damages due to lifetime care needs
  2. Surgery: Particularly orthopedic, cardiac, and neurosurgery
  3. Emergency medicine: Where time pressure and limited patient information create challenging conditions
  4. Anaesthesiology: Due to the high-risk nature of the specialty
  5. General practice: Due to the volume of patients seen and the challenge of identifying serious conditions from common symptoms.

How to prove medical malpractice and the evidence required

In medical malpractice cases, the burden of proof rests with the claimant.

Successfully proving a malpractice claim requires specific types of evidence and expert support to demonstrate that the standard of care was breached and that harm was caused as a result.

The role of expert testimony

Expert testimony is a critical component in most successful medical malpractice cases in Australia.

Independent medical experts

These professionals must assess the case and provide their opinion on whether the standard of care was met. Experts must be qualified in the same field as the healthcare provider involved in the medical malpractice claim. Their testimony typically addresses both the standard of care and the causation of the harm.

Credibility of experts

The qualifications and objectivity of the expert witnesses are essential in determining the case’s outcome. The courts rely heavily on expert testimony that is objective, detailed, and aligned with current medical standards. Experts may provide written reports, participate in conferences with opposing experts, or testify in court.

Important forms of evidence

In addition to expert testimony, several forms of evidence are crucial in medical malpractice claims.

1. Medical records

These are the foundations of most malpractice cases.

It includes:

  • Complete treatment history: All records related to the care in question
  • Contemporaneous notes: Records made at the time of treatment hold particular value in assessing the quality of care
  • Test results: Laboratory findings, imaging studies, and other diagnostic information.
  • Medication records: Documentation of all prescribed and administered medications.

 

Tampering with medical records is a serious offence and can strengthen the malpractice claim.

2. Witness testimony

Testimonies from various witnesses can significantly impact a case.

These can be from:

  • Healthcare providers who observed the care or treatment
  • Family members who witnessed interactions with healthcare providers or observed changes in the patient’s condition
  • The patient themselves, offering firsthand accounts of their experience and the resulting harm.

 

Witness testimony is particularly useful in establishing timelines or communication failures that may not be documented in medical records.

3. Consent documentation

Informed consent plays a critical role in many malpractice cases, as it ensures patients are fully aware of the risks and alternatives before undergoing treatment.

Key forms of evidence include:

  • Signed consent forms can indicate what risks were or were not disclosed
  • Evidence of discussions such as notes or recordings of consent conversations
  • Hospital policies that outline institutional procedures for obtaining informed consent

 

Lack of proper consent documentation or evidence that consent was obtained under duress can strengthen a malpractice claim.

4. Additional supporting evidence

Other forms of evidence that may strengthen a medical malpractice case include:

  • Photographic evidence of injuries or conditions
  • Video recordings showing the patient’s condition before and after the alleged malpractice
  • Hospital policies and procedures that may demonstrate failure to follow institutional standards
  • Training records for healthcare providers involved
  • Statistical data on complication rates or outcomes for similar procedures
  • Communications between healthcare providers about the patient’s care.

Proving intent in medical malpractice

A key distinction between negligence and malpractice is the consideration of intent.

Evidence that may help establish intent includes:

  • Documentation showing the provider was aware of risks but proceeded without taking proper precautions
  • Evidence of prior similar incidents involving the same provider
  • Records indicating the provider failed to review essential information before proceeding with treatment
  • Documentation of financial incentives that may have influenced the provider’s treatment decisions

 

By carefully gathering and presenting this evidence, claimants can strengthen their case and demonstrate that medical malpractice occurred.

Frequently Asked Questions about medical malpractice claims

To have a valid medical malpractice claim in Australia, you typically need evidence showing:

  1. A healthcare provider owed you a duty of care
  2. The provider breached that duty by deviating from accepted medical standards
  3. This breach directly caused your injury or harm
  4. You suffered quantifiable damages as a result

In Australia, there are strict time limits (limitation periods) for filing medical malpractice claims:

  • Claims generally must be filed within three years from the date the injury became known (the ‘date of discoverability’)
  • For children, the limitation period usually begins when they turn 18
  • In cases involving cognitive impairment, special provisions may apply
  • Courts may grant extensions in exceptional circumstances, but this is at their discretion.

The timeline for medical malpractice cases varies significantly based on:

  • The complexity of the medical issues involved
  • Whether liability is disputed
  • The severity of the injuries
  • Court schedules
  • Whether settlement before the trial begins is possible.

 

Simple cases might resolve in 12 to 18 months, while complex cases can take two to four years or more. Our attorneys work diligently to move your case forward as efficiently as possible while still ensuring thorough preparation.

Not every adverse medical outcome constitutes malpractice.

Remember:

  • Medical procedures inherently involve risks, and complications can arise even when proper care is provided
  • Malpractice occurs when the adverse outcome is the result of care that falls below accepted medical standards
  • The key consideration is whether the healthcare provider’s actions or omissions were reasonable under the circumstances, not just whether the outcome was negative
  • An unexpected or disappointing result alone does not automatically indicate malpractice.

In medical malpractice cases, damages are calculated based on factors such as the severity of the impact, the claimant’s age, and the specific circumstances of the injury.

Damages you may be entitled to include:

  • Pain and suffering: Up to $650,000, depending on the severity of the injury
  • Home care: Potentially millions, depending on the level of care required and any necessary home modifications.
  • Loss of employment income: Compensation for lost wages, salary, or contractor fees could amount to millions, based on the claimant’s past, present, and future earning capacity
  • Loss of superannuation: Claimable at its full value
  • Legal costs: A significant portion of litigation costs may be covered.

 

Your family members may also be entitled to make a claim for their pain and suffering through a nervous shock claim.

At GMP Law, we collaborate with medical experts to ensure every aspect of your damages is accurately calculated and effectively presented.

Medical malpractice claims can be brought against hospitals and healthcare systems, not just individual practitioners:

  • Hospitals have a duty to maintain safe facilities and adequate staffing
  • They are responsible for proper credentialing and supervision of staff
  • System failures such as communication breakdowns, record-keeping errors, or inadequate policies can form the basis for claims
  • In many cases, both individual practitioners and the facility may share liability.
