Maloinato and Australian Postal Corporation (Compensation)

This matter concerned an appeal by the applicant, Maloinato, against a decision by Australia Post to deny her compensation for degenerative changes in her lower lumbar spine, specifically osteoarthritis and secondary spondylolisthesis. The applicant contended that her employment with Australia Post had progressively aggravated these pre-existing degenerative conditions. Australia Post maintained that the applicant's work had not contributed to a significant degree to her condition or its aggravation.

The court was required to determine two primary issues: first, whether the applicant suffered from an ailment or an aggravation of an ailment within the meaning of the relevant Act; and second, whether such ailment or aggravation was contributed to, to a significant degree, by her employment with Australia Post. The applicant initially argued for an injury other than a disease, but at the conclusion of the hearing, conceded that her spinal disorder was a disease as defined by section 5B of the Act, narrowing the focus to the contribution of her employment.

In reaching its decision, the court considered the evidence of both the applicant and medical experts, including Professor McGill and Dr. Ellis. The court accepted Professor McGill's evidence that the applicant's symptoms were referable to osteoarthritis and secondary spondylolisthesis, and not directly caused by her work. Crucially, the court found that while the applicant's employment involved physical tasks and a lengthy duration, there was no identifiable incident at work that could be attributed to her symptoms or their increase. Furthermore, the court noted that the applicant's symptoms had continued to worsen even after she ceased working, which was inconsistent with her employment being a significant contributing factor. Applying section 5B of the Act, which defines "significant degree" as "substantially more than material," the court was not satisfied that the applicant's employment had contributed to a significant degree to the aggravation of, or the condition suffered by, the applicant.

Consequently, the court affirmed the decision under review, finding that Australia Post had no present liability to pay the applicant compensation for her condition.
