A dispute between longtime presenter Mary Kostakidis and the network arose in August 2007, when she walked out of the network in frustration at what she saw as increased commercialisation at the network, and a shift away from the original values of both the news service and the station in general. It was widely speculated that Kostakidis' contract stipulated she would be the network's main news presenter, and maintain editorial control over bulletins, somewhat altered by World News Australia's change in format. Kostakidis took legal action against SBS for breach of contract.
