Regarding the recent rise in One Nation opinion poll figures, Newspoll has released their quarterly analysis which includes a breakdown of polling from January 12 to March 16. The initial figures quoted here are for Queensland voting intention if a federal election was held.
One nation has hit the lead in the primary vote at 30%, followed by Labor at 27% and the LNP on 23%. As far as I know, the LNP still leads over One Nation in polls regarding a state election due to the relatively popular incumbent LNP state government.
Federally, One Nation is running in second place everywhere except Victoria where the coalition has a 1% margin over them. One Nation's popularity with voters aged 18 to 34 had also risen to 19 per cent from 8 per cent during the last quarterly analysis in December, while also becoming the third most popular party (19 per cent) for younger Australians behind Labor (30 per cent) and the Greens (26 per cent). The polling found One Nation had also had a rise in support from female voters (26 per cent) as compared to male (25 per cent). The support of Australians from diverse backgrounds, who spoke a language other than English at home, for One Nation was also up from 9 per cent to 19 per cent. While the new figures brought it level with the Coalition, both parties trailed Labor’s 35 per cent majority in this group.
