Jim Ball (radio personality)
Ball's program typically consists of him discussing various issues (especially current events, politics and history) with callers. Ball is frank and does not shy away from politically incorrect topics. Like most radio announcers on the AM band in Sydney, Ball is politically conservative; he claims to represent traditional Australian values. According to Ball, the major threats to these values are a naive and uninformed view of Islam by many Australians (including the media), apathy and political correctness. Ball is also a staunch critic of multiculturalism and says that immigrants to Australia should be encouraged to integrate into mainstream Australia and accept "core Australian values."
Ball began on 2GB back in 1999 and constantly won the ratings manning the midnight to dawn shift. On 7 March 2008 Jim announced to his then audience that he would be changing radio station and was replaced by David Oldfield. Jim took over 2UE's midnight to dawn program "New Day Australia" on 17 March, replacing Clive Robertson. On 12 March 2010, Ball unexpectedly quit 2UE  and returned to 2GB on 12 April replacing Oldfield himself.
