ANTI-immigration campaign-er Pauline Hanson will likely return to Canberra two decades after first exploding on to the national scene.
Ms Hanson is set to claim a Senate spot in Queensland after her One Nation cleaned up almost 20 per cent of the primary vote in some Lower House seats in the state. 
One Nation could win a second Queensland Senate seat, with little-known engineer Malcolm Roberts a chance to sit alongside Ms Hanson in the Upper House.
Ms Hanson, who became a household name with her fierce anti-Asian and now anti-Muslim rhetoric, was first elected to federal parliament in 1996 and was defeated in 1998.
In Victoria, Derryn Hinch is also among the contenders to pick up a Senate spot when Parliament returns next month.
Ms Hanson said she had received a very good reaction from voters throughout Australia, who were fed up with the major parties.
"Having travelled around the country quite extensively, especially Queensland in the last month, there has been very strong on-ground support (and) I'm feeling very confident to pick up the seat," she said.
"There's a huge swing against the major political parties. People are fed up. They feel they're not listened to." Bolstered by his number one position on the ballot paper, Hinch was quitely confident last night.
"I'm hopeful, but by no means over-confident that I'll pick up a seat," Hinch said.Hinch has campaigned on a populist tough-on-crime platform including sentencing, bail and parole reforms and a public register of sex offenders. The 72-year-old has been jailed twice for contempt of court and convicted three times for breaching suppression orders.
