After graduating from the University of Queensland with a degree in arts and law, she practised as a solicitor in Brisbane and lectured in commercial law in Rockhampton before becoming a journalist for The Courier-Mail, Brisbane's only daily newspaper. Within a year she moved to the now defunct The Times on Sunday and has since worked for The Age, The Canberra Times and A Current Affair, a nightly current events programme on the Nine Network.
Margo Kingston achieved notoriety in 1998 when she led a sit-in of journalists at the Federal election campaign launch of the One Nation Party in the Queensland town of Gatton - the journalists were unhappy with the party's treatment of the media during the campaign. Margo's experiences during this interesting election campaign are recorded in her book, Off The Rails: The Pauline Hanson Trip (ISBN 1865081590).
Though Margo Kingston is openly left-of-centre in her political leanings, she is generally respected by all sides of politics for her tough, no-holds-barred style of political journalism.
Margo Kingston currently confines herself primarily to opinion pieces on the editorial pages of The Sydney Morning Herald though she occasionally writes news reports on Australian politics. She also writes a webdiary on the Herald's website in which she and contributors from the general public record their opinions on current events. Margo Kingston is also a regular guest on Late Night Live, a nightly radio programme on the Australian Broadcasting Corporation's Radio National network.
