Wildcard seats to watch (and margin)
Coalition
Petrie (Qld) 0.5%
A mini-bellwether for the past couple of decades, this north-ofBrisbane seat has gone with the government of the day since 1987. Luke Howarth claimed the seat in 2013 but it remains one of the most marginal in Australia.
Solomon (NT) 1.4%
One of only two lower house seats in the Northern Territory, Solomon takes in the cities of Darwin and Palmerston. Sitting MP Natasha Griggs is under threat from Labor, which is confident of picking up the seat.
Eden-Monaro (NSW) 2.9%
The seat east of Canberra is well known for having been won by the party that formed government since 1972. Labor's Mike Kelly won the seat in 2007, but lost to former Liberal staff er Peter Hendy in 2013. The pair are facing off again.
Lindsay (NSW) 3.0%
Situated on Sydney's western outskirts, this seat has been won by the party that formed government at every election since it was first contested in 1984. Liberal Fiona Scott won the seat in 2013 but has since come under fire for switching allegiances from Tony Abbott.
Cowan (WA) 4.5%
This seat covers Perth's north eastern suburbs. A 2016 redistribution hurt the chances of incumbent Liberal MP Luke Simpkins and Labor is hoping to pick it up on election night.
Burt (WA) 6.1%
This newly created seat in Perth's south is notionally Liberal, but is expected to be closely contested. The Liberal candidate is Matt O'Sullivan, while Labor's candidate Matt Keogh built a profile in 2015's byelection for the neighbouring seat of Canning.
Dawson (Qld) 7.6%
Stretching north from Mackay to Townsville, this seat has been held by Labor for just three years since 1975. The sitting member is controversial LNP MP George Christensen and Labor feels the seat is in play, despite its high margin.
Higgins (Vic) 9.9%
This inner southeast Melbourne seat has a significant gay community and sitting Liberal member Kelly O'Dwyer has expressed support for same-sex marriage. The Greens have aspirations in Higgins after winning the state seat of Prahran.
Sturt (SA) 10.1%
This electorate takes in Adelaide's inner east. First contested in 1949, it has been held by Labor for fewer than five of the ensuing 64 years. Christopher Pyne has held the seat since 1993 but it could be lost to Nick Xenophon candidate Matthew Wright.
  Mayo (SA) 12.5%
In 2008 Greens candidate Lynton Vonow gave the Liberal Party a scare in the byelection that followed Alexander Downer's retirement. Incumbent Liberal Jamie Briggs is at risk of losing the seat to Rebekha Sharkie from the Nick Xenophon Team.
Cowper (NSW) 13.2%
Situated on the north coast of NSW, this seat has only been won by Labor once, in 1963. Nationals MP Luke Hartsuyker has held the seat since 2001 but could lose it to former independent MP Rob Oakeshshott.
New England (NSW) 19.5%
This northern NSW seat will be fought between former independent member Tony Windsor and Nationals Deputy Prime Minister Barnaby Joyce, who took the seat following Windsor's retirement in 2013.
ALP
Dobell (NSW) 0.2%
Karen McNamara won this central coast seat for the Liberals in 2013 from former union off icial Craig Thomson. Emma McBride will again contest for Labor after falling less than one point short in 2013.
Batman (Vic) 21.0%
Named after one of the founders of Melbourne, this electorate covers the city's northern suburbs. Labor powerbroker David Feeney switched from the Senate to the safe Labor seat in 2013, but is tipped to face a tight battle against the Greens.
Independent
Indi (Vic) 0.3% This rural seat in north-eastern Victoria provided one of the 2013 election's closest contests as independent Cathy McGowan ousted Liberal frontbencher Sophie Mirabella by 439 votes. The two will again contest the seat, as will National Marty Corboy
