One Nation NSW was a minor Australian political party, which operated exclusively in the state of New South Wales (NSW), in the early 2000's. The party was a splinter group of Pauline Hanson’s One Nation (PHON). It was a socially conservative populist party on the right of the political spectrum and its policies were similar to that of the original One Nation party, advocating reduced immigration levels, an end to Australia’s policy of multiculturalism and an end to what it perceives to be overly favourable treatment of Australian indigenous Aboriginal population.
The party arose as a result of internal divisions within PHON in October 2000 after Pauline Hanson expelled David Oldfield, co-founder of PHON and the sole representative of that party in the NSW State Parliament. At the 2000 NSW State Conference Hanson accused Oldfield of abusing his authority, usurping power and setting up alternative political parties under his control. His expulsion created even more instability in a party which was constantly embroiled in scandal and internal strife and the party saw a split in its NSW division. As a result, One Nation NSW was formed in 2001. The new party took advantage of electoral party registration laws to register itself as political party under the ‘One Nation’ name with the NSW electoral commission, and achieved registration in April, 2002. The effect of this was that the original PHON party was now unable to gain registration for NSW elections, and therefore any candidates which that party chose to represent them at state elections could not use the party name. Consequently, PHON could only contest Federal elections in NSW under the 'One Nation' banner, whilst the Oldfield group could present itself as 'One Nation' only at state elections.
One Nation NSW encountered some internal ruptures in 2002-2003 during the preselection process for the March 2003 NSW election. Brian Burston, (a former National Director of PHON) had been preselected by a party conference in December 2002 for 1st place on the party ticket, for the election to the Upper House, the Legislative Council (LC). Oldfield however, had intended that his wife Lisa Oldfield, secure this position. He therefore summoned a second meeting of party members in January 2003, which saw a reversal of the December decision to give Burston the top spot on the ticket, in favour of Lisa Oldfield. Burston and his supporters filed legal action, and the court upheld the initial party decision of December, which gave Burston the leading position on the ticket.
