If you haven't heard about this one (and I expect most Australians will have, it's just the headline grabbing story), read about it in detail here.
Essentially, a woman in employment for a Commonwealth government agency was sent on a work trip to a town in NSW. After working during the day, she met a male friend from the town at her motel. They had sex, and during this time a light fitting fell from the wall, hitting the woman. The light hit her face, injuring her nose and teeth.
She applied to ComCare (the agency that administers worker's compensation for public servants) and they denied her claim. Now she has won a court case, five years after the incident, with the Judge finding she is entitled to compensation.
