Australia has an independent national broadcasting service - the Australian Broadcasting Commission (ABC). The ABC is legally required to be objective, which in practice encourages viewers to be swinging voters. However, the lack of anti-media-monopolisation laws in Australia means that a powerful Media Mogul can act as the propaganda arm of a particular party whether it is in majority government or not. The Conservative Liberal-National-Coalition Party of Australia always strives to erode, deconstruct and disempower the ABC. The other major party - the Australian Labor Party strongly supports the ABC and its non-partisan mandate. Therefore the political playing field in Australia is definitely not level and the current Government very much likes it that way, so it will never act to curb Rupert Murdoch's powers of influence in the country.
