The firebrand senator first won her spot in the Senate in 2013 as part of the Palmer United party, but her relationship with Clive Palmer quickly disintegrated. She left Palmer United late in 2014 and struck out on her own as an Independent.Senator Lambie's views cannot be easily characterised. She takes a conservative stance on national security issues, but she has become increasingly hostile to the Coalition's economic agenda, heaping praise on Labor's plans for a Royal Commission into the banks.And by her own assessment, she is closest to the Greens on several issues — recently saying "they care about the veterans, they care about aged care, they care about pensioners out there that aren't getting enough money".Senator Lambie is unlikely to back many of the Government's signature measures in the Senate.She was critical of the Coalition's bill to re-establish the Australian Building and Construction Commission, saying the legislation "had been drafted by a room full of monkeys on a typewriter".She has also campaigned against the Coalition's proposed changes to superannuation.Senator Lambie has not said if she would back the Coalition's plan to cut the company tax rate but has previously criticised tax cuts for big businesses, accusing the Liberal party of pandering to the "big end of town".If at first you don't succeed, try and try again. Well, that seems to ring true for Pauline Hanson.Eighteen years after she lost the Queensland seat of Oxley, the right-wing, anti-immigration campaigner is back in Federal Parliament.After serving one term in Parliament, the former fish and chip shop owner has been parodied and pilloried, sent to prison for electoral fraud — a conviction which was later overturned — and written off countless times by the political class.Now, she is on track to win up to four Senate seats.Her party's policies are to stop all further Muslim immigration, including the intake of refugees; ban the burqa and any other full face coverings in public places; hold an inquiry or Royal Commission into Islam to "determine if it is a religion or political ideology" and install surveillance cameras inside mosques and Muslim schools.The party also wants to introduce a National Identity Card for Australians who access taxpayer funded services and revoke any free trade agreements that are not in Australia's interests.The veteran broadcaster will be a political neophyte in the Senate, making it difficult to predict exactly how he'll vote on some issues.Mr Hinch — who previously served time in jail for breaching court suppression orders and publishing details about murderers and sex offenders — has vowed to push for a national public register listing convicted paedophiles.He could be more receptive to the Coalition's agenda than some of his fellow crossbenchers.He has told the Australian newspaper he supports the Coalition's policy to cut the company tax rate "in principle" — although he wants to see the detail of the legislation.But he is more sceptical about the Coalition's plan to re-establish the building industry watchdog, the Australian Building and Construction Commission. He has also raised some concerns about the Coalition's proposed changes to superannuation.The X-Factor is strong in South Australia, and it is likely popular senator Nick Xenophon will be returned to Capital Hill with two bench buddies — his campaign manager Stirling Griff and staffer Sky Kakoschke-Moore.Senator Xenophon is no stranger to the national spotlight, but his field of candidates across the House of Representatives and Senate were widely criticised for being unknown entities, riding on the coattails of a man who has successfully campaigned that neither the Liberal party or Labor have the interests of South Australia at heart.His previous attempts to expand his political posse have not ended well.While a member of the SA upper house, Anne Bressington was elected on his ticket only for the pair to later experience a bitter split.NXT has campaigned on a pro-manufacturing platform, taking somewhat of a protectionist stance on the issue of the local steel industry after the downfall of Arrium in the South Australian city of Whyalla.Senator Xenophon has long called for greater accountability in government and better water security in the Murray Darling basin — particularly for downstream communities in his home state.Stirling Griff has spent many years working with Senator Xenophon as his campaign manager, and only narrowly missed out on being elected on his ticket at the 2013 election.A former banker, marketing executive and chief executive of the Retail Traders Association (now the Australian Retailers Association), Mr Griff was the key target of Labor attacks on the NXT over penalty rates.He was asked if he would support Coalition legislation to scrap penalty rates for small businesses, and he replied he would consider it.Skye Kakoschke-Moore started working for Nick Xenophon in 2010 as an electorate officer and eventually became his legislation and policy adviser.The law and economics graduate was born in Darwin, moved to Oman with her family as a child and settled in Adelaide in 2005.According to her biography, she travelled extensively throughout the Middle East which has sparked her interest in the role governments play in shaping people's lives.She also has a strong interest in migration policy having worked for the Australian Refugee Association while studying at university.Ms Kakoschke-Moore is probably the least well known of the Nick Xenophon candidates.David Leyonhjelm rose to prominence after securing a Senate seat at the 2013 election, as one of the key crossbenchers Tony Abbott needed to woo in order to pass key pieces of legislation.The libertarian is strongly against big government, and launched a "nanny state" Senate inquiry last term, which investigated everything from Sydney's lock-out laws to the compulsory wearing of helmets on bikes.Senator Leyonhjelm attracted attention last year for supporting the importation of the controversial Adler lever-action shotgun.He was one of the most vocal critics of the Government's proposed changes to the Senate voting system, which would have made it harder for minor parties such as the Liberal Democrats to be elected.He supported the Coalition's "no jab, no pay" policy saying the least parents can do is "immunise their bundles of dribble and sputum, so they don't make the rest of us sick".Brian Burston joined One Nation soon after the party was founded.He is a former national director of One Nation and an ex-deputy mayor of Cessnock.Senator-Elect Burston was sacked by Pauline Hanson and party co-founder David Oldfield after a dispute in October 2000.His twin brother Graham also ran for One Nation in the seat of Paterson.He has previously worked as a parliamentary advisor and research officer in the New South Wales Parliament.His website cites he is particularly passionate about Australia's border security and national identity.A former Liberal party member and candidate, Bob Day AO was elected as a Family First party Senator for South Australia in 2013.He was one of the fiercest opponents of the Coalition's proposed changes to Senate voting laws, even attempting to challenge the legislation in the High Court during the election campaign.Senator Day's experience running a construction business led Prime Minister Malcolm Turnbull to reach out and ask him to lead negotiations with other crossbench senators on the reintroduction of the Australian Building and Construction Commission — the piece of legislation that was blocked in the upper house and sent the nation to an early double dissolution election.The West Australian secured the 11th spot in the state's Senate race, but there are questions over whether he will be able to take his seat.Mr Culleton may be deemed ineligible because of a conviction in New South Wales, and a pending trial in Perth over the alleged theft of a hire car.He said he was convicted in NSW in his absence, because he could not leave WA, as he was on bail.In the event he cannot take his Senate seat, his brother-in-law or wife could take the seat — who were the number two and three candidates on the One Nation ticket.He said he joined One Nation with strengths in agriculture and banking.Mr Roberts is a prominent climate change sceptic with the Galileo Movement.The Queenslander spent the early years of his life in India before working in the coal industry.In a statement, Mr Roberts said he "spent the last nine years working pro bono checking alarmist climate claims made by academics".Mr Roberts has called for a re-think of Section 18C of the Racial Discrimination Act, and said he will focus on "issues like flawed assumptions driving the budget, massive debt, and tax systems that are killing business, exports and jobs".
