"In [Barwon Spinners Pty Ltd v Podolak] the court made it plain that the plaintiff must identify the compensable injury (in respect of which he or she claims there is an entitlement to compensation under the [Act]) and establish that it occurred on or after 20 October 1999. Expressions used by it such as "referable" or "linked" to employment were alternatives to, or short hand for, the words in s 134AB(1), "arising out of or in the course of, or due to the nature of, employment". The court effectively said that, where the injury has its foundation in circumstances that were referable to the worker's employment prior to the due date but continued to evolve thereafter, it was for the worker to identify, for the purposes of subs (1), the compensable injury in respect of which he or she claims to be entitled to compensation and establish that it is referable to employment on or after the due date, but not before it. The Court did not say, however, that merely because the injury had its foundation in the work environment prior to the due date and has been ongoing it necessarily meant that the plaintiff was "out of court" for the purposes of subs (1). As Ashley JA explains, there is an important difference between injury and the consequences of injury. Whether the injury is compensable and whether it occurred post the due date are questions of fact that must be determined by reference to the circumstances of the particular case. Thus, for example, it may be that an injury that had its onset in the work place some years prior to 20 October 1999 and was "ongoing" or evolving, but which only manifested itself, say, at the end of 1999, would not be regarded for the purposes of subs (1) as a compensable injury that relevantly occurred after the due date. On the other hand, as his Honour makes clear ... the evidence may nevertheless show that the injury, as distinct from a manifestation of an earlier injury, in respect of which the worker became "entitled to compensation" within the meaning of subs (1), was sustained after the due date."[8]
