JAILBIRDS Derryn Hinch and Pauline Hanson are hot tips to pick up Senate spots when Parliament returns next month.
Boosted by his number-one position on the ballot paper, Hinch was "sanguine" after a full day campaigning yesterday. 
The controversial broadcaster, who has been jailed for contempt of court and convicted of breaching suppression orders, took his "Justice Bus" to booths in the Melbourne suburbs of Collingwood, Richmond and Albert Park as he lobbied for votes.
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 booked a suite at a Sofitel hotel last night where he planned to watch the coverage with campaign staff before a string of media commitments this morning.
"When I get in, the first thing I want to do is get a Senate inquiry into the Family Court and child welfare agencies," Mr Hinch said.
Motoring Enthusiast senator Ricky Muir, who entered Parliament at the last election, is likely to lose his seat to the veteran broadcaster.
The Victorian senator, who was first elected in 2013 with just half of one per cent of the primary vote, conceded he would struggle to hold his seat.
Serial candidate and One Nation founder Pauline Hanson is more confident of securing one of 12 Queensland Senate positions.
"The figures that I've got, what I'm hearing is quite positive," Ms Hanson said. "It's going to be quite interesting. And not just in Queensland but across the rest of the country."She was first elected to federal parliament in 1996 and then defeated in 1998 federal election.
