[5] "Injury" is defined by s. 34 of the WorkCover Queensland Act to be "personal injury arising out of, or in the course of, employment if the employment is a significant contributing factor to the injury." Superficially, therefore, the submission by Dr Cross has some merit in suggesting that the Personal Injuries Proceedings Act procedures may apply to Mr Ferrari's case on the basis that he has not suffered an injury as defined under the WorkCover Queensland Act. He relied, in particular, on the failure to use the words "and in relation to which that Act applies" in s. 6(2)(b) where they were used in s. 6(2)(a) of the Personal Injuries Proceedings Act to argue that the legislature intended to exclude from the Personal Injuries Proceedings Act only workers who suffered an "injury" as defined by the WorkCover Queensland Act. The approach does not deal adequately, however, with the abolition of his right to seek damages effected by s. 253 of the WorkCover Queensland Act even in the residual category of common law claims described as "gap cases" by Thomas JA in Hawthorne v Thiess Contractors Pty Ltd.
