There is no hard and fast rule regarding whether contraction of the COVID-19 virus is compensable under the Workers’ Compensation & Injury Management Act 1981 (the Act) – it will need to be determined on the facts of each case.

There is no doubt that COVID-19 and its symptoms would meet the definition of disease in the Act, which is very broad:

disease includes any physical or mental ailment, disorder, defect, or morbid condition whether of sudden or gradual development.

The critical question is whether the disease (or the effects of the disease) fall within any of the definitions of injury in s.5(1) of the Act:

Injury means —

(a) a personal injury by accident arising out of or in the course of the employment, or whilst the worker is acting under the employer’s instructions; or
(b) a disease because of which an injury occurs under section 32 or 33; or
(c) a disease contracted by a worker in the course of his employment at or away from his place of employment and to which the employment was a contributing factor and contributed to a significant degree; or
(d) the recurrence, aggravation, or acceleration of any pre-existing disease where the employment was a contributing factor to that recurrence, aggravation, or acceleration and contributed to a significant degree; or
(e) a loss of function that occurs in the circumstances mentioned in section 49,

but does not include a disease caused by stress if the stress wholly or predominantly arises from a matter mentioned in subsection (4) unless the matter is mentioned in paragraph (a) or (b) of that subsection and is unreasonable and harsh on the part of the employer

Existing case law strongly suggests that a worker’s infection with the disease will be found to have occurred in the course of the employment if there is evidence:

  • to establish the probable time of infection
  • the infection occurred during work hours or at a place or during an activity required for the purpose of the employment, incidental to the employment, or was encouraged by the employer

Precedents

In Sara v G&S Sara Pty Ltd [2021] NSWPIC 286, the Personal Injury Commission of New South Wales determined the widow of a worker who died from COVID-19 while on a business trip to the USA was entitled to a death benefit of $834,000 plus other expenses.

The Commission determined under NSW legislation that COVID-19 satisfied the definition of disease. The critical issue was whether the deceased was infected in the course of the employment. The Commission applied Hatzimanolis v ANI Corporation Ltd and Comcare v PVYW to conclude that while it was possible for the deceased to have been infected while engaged in activities which were not work related, the period of travel to the USA was clearly within the course of his employment as he was directly encouraged and induced by his employer to travel there for business. Further, the Commission found based on the available evidence – including the expert opinion of an Infectious Diseases Specialist as to the disease’s normal incubation period – that on the balance of probabilities the deceased became infected while travelling to the United States.

The requirement that the employment contributes to the contraction of the disease be significant is not a high threshold to meet. In Mokta v Metro Meat International Ltd [2005] WASCA 143 Pullin J held that “significant”, for the purposes of the Act, means “not insignificant”. This means that the employment need not be the only contributing factor but must be material in its contribution.

The situation in WA

It is likely that when community transmission becomes more prevalent in WA, it will become more problematic for some workers to demonstrate their employment was a significant contributing factor to the contraction of COVID-19. This is because it will become increasingly difficult to establish that contracting COVID-19 was associated with the course of employment, and not just the inevitable result of ordinary day to day public interaction within the community. Valid claims for compensation under the Act will have stronger prospects where individuals can demonstrate prolonged periods of effective isolation before being required to be exposed to the virus because of their employment.

In more seriously infected patients, definition (a) of injury may also be applicable. The COVID-19 virus can cause profound respiratory failure and other identifiable pathological changes including strokes and heart attacks which would constitute an internal ‘personal injury by accident’. Based on definition (a) of injury, the relevant test for the entitlement to compensation in that situation becomes ‘arising out of or in the course of the employment’. The same principles will apply to the ‘course of employment’ under this definition as for type (c) injuries.
