12.11.1 - Compensation table for physical impairment Amounts in this table are indexed using movements in the Consumer Price Index (CPI).
Note: Since the CPI between the December 1996 and December 1997 quarters decreased, the levels of compensation for 1997/98 and 1998/99 injuries remain the same.
Following legislative changes in December 2003 the formulas for calculating non-economic loss in respect of permanent impairment have been amended. Some amounts of compensation for non-economic loss have been increased in certain circumstances. To convert whole person physical impairment to an IB rating in accordance with legislative amendments for injuries on or after 3 December 2003 see 12.11.11 - Table of Modification to Degrees of Impairment for the Purposes of Section 98C
Percentages marked * relate to the worker’s impairment benefit rating where the whole person impairment assessment has been made in accordance with Chapter 3 of the AMA Guides under S98C(2A)

Definition of injury The definition of injury has both a “general” sense, and an “extended” one.
Injury in the “general sense” relies on the first part of the definition of injury in section 5 of the Act (“injury” means any physical or mental injury…) and carries with it no requirement to show that work contributed to it at all.
If not injury in the general sense, the claimed condition must come within the notion of injury in its “extended” sense:
a disease, which includes any physical or mental ailment, disorder, defect or morbid condition whether it occurred suddenly or developed gradually
or
the aggravation, acceleration, exacerbation or recurrence of any pre-existing disease
Whether an event fits within the notion of injury in its general sense depends on whether it is accompanied by sudden physiological change. This is a question of fact in each case.
Sudden physiological change
There is limited authority on what constitutes “sudden physiological change.” Courts have generally been asked to consider it in the context of haemorrhagic strokes, which occur when a blood vessel bursts. They have emphasised that:
a sudden internal trauma is no different than a sudden external one
and
every case must be examined on its merits
The question of whether sudden physiological change is present or not is determined by an examination of the factual circumstances surrounding the onset of a medical condition and detailed medical evidence as to the internal processes involved in the onset of the condition. It is important to bear in mind the rationale stated by the courts in stroke cases, that a breaking artery should not be treated differently than a breaking leg.
Diseases and pre-existing injuries
If “sudden physiological change” is not present, a worker must establish an injury in its “extended” sense.
In its extended sense, injury incorporates a disease, or a recurrence, aggravation, exacerbation or deterioration of a pre-existing injury or disease.
At different times, the Act has stipulated that differing levels of work contribution have to be present for such a condition to constitute an injury.
Between 1/9/85 and 30/11/92
employment must have been “a contributing factor”
Between 1/12/92 and 2/12/03
employment must have been a “significant contributing factor”
Heart attack and stroke injuries
From 3 December 2003, “heart attack and stroke injuries” as defined in Section 5 of the Act, are specifically provided for. Employment must be a significant contributing factor, irrespective of whether the injury constitutes “sudden physiological change, or is connected with a pre-existing condition or disease, or not.”
