Perry and Go Marine Group Pty Ltd (Compensation)

This matter concerned a claim for compensation by Mr Perry against Go Marine Group Pty Ltd. Mr Perry sought compensation for an injury to his right knee, alleging that his employment had caused or materially contributed to his ongoing incapacity. The dispute centred on whether a 2010 workplace incident constituted an injury that caused ongoing incapacity or aggravated a pre-existing condition to a material degree, thereby entitling him to compensation. The decision was made by Senior Member R Bellamy.

The legal issues before the court were whether Mr Perry's right knee condition constituted an "injury" as defined by the relevant legislation, and specifically, whether the 2010 incident caused ongoing incapacity or materially aggravated a pre-existing degenerative condition. The court was required to determine if the employment contributed to the ailment in a material degree and whether that contribution continued to be a factor in Mr Perry's ongoing condition.

Senior Member Bellamy considered the medical evidence, including reports from orthopaedic surgeons Dr Greg Gillett and Dr Cameron Cooke, and Professor Steadman. The court noted that Mr Perry had a pre-existing degenerative condition in his right knee, which had been surgically treated following an incident in 1995. The 2010 incident involved soft tissue damage. The court applied the definition of "injury" under the Act, which includes an aggravation of a physical injury that arose out of, or in the course of, employment, and that an aggravation of a pre-existing condition could be considered a "disease" if contributed to in a material degree by employment. Drawing on the principles from *Woodhouse v Comcare*, the court emphasised that for liability to continue, the ailment must remain an "injury" and owe its existence to the material contribution of employment, not merely factors unconnected to it.

Ultimately, the court was not satisfied that the 2010 injury materially contributed to Mr Perry's ongoing right knee condition in June 2012 or thereafter. While acknowledging that the 2010 incident caused temporary soft tissue damage, the court found that it did not accelerate the progression of the underlying degenerative condition. Consequently, the reviewable decision was affirmed.
