Aftermath
Four hours after the close of polls, at approximately 10pm ACDT, incumbent Premier Jay Weatherill telephoned Steven Marshall and conceded defeat. Weatherill subsequently publicly announced that he had conceded, saying, "I'm sorry I couldn't bring home another victory, but I do feel like one of those horses that has won four Melbourne Cups and I think the handicap has caught up with us on this occasion." Marshall claimed victory saying, "A massive thank you to the people of South Australia who have put their trust, their faith in me and the Liberal team for a new dawn, a new dawn for South Australia!" After the SA Best party failed to win a seat in the lower house, Nick Xenophon ruled out a return to federal politics.
Following the election outcome, Weatherill resigned as state Labor leader and returned to the backbench. Outgoing Minister for Health Peter Malinauskas

in government due to its traditional dominance of Adelaide. South Australia is one of the most centralised states in Australia; Adelaide is home to over three-quarters of the state's population. To a greater extent than other state capitals, Adelaide is decisive in deciding state election outcomes. Since the end of the Playmander, most elections have seen Labor win most of the metropolitan seats, with most of the Liberal vote locked up in safe rural seats. In 2010, for instance, the Liberals won 51 percent of the two-party vote on a swing that should have been large enough to deliver them government. However, they only won nine seats in Adelaide, allowing Labor to eke out a two-seat majority. In 2014, while picking up a two percent two-party swing, the Liberals were only able to win an additional three seats in Adelaide.

announced a few SA Best lower house candidates. Polls had included Xenophon's party as one of the four parties they monitored explicitly since February 2016. Originally, SA Best planned to only contest 12 seats. This was increased to 20.[ On 27 January, a landmark was passed when Xenophon announced eight new candidates, making a total of 24. This was the minimum number to be theoretically capable of forming majority government in the 47-seat house. On 1 February, Xenophon said it was likely the total number of SA Best lower house candidates would be around 30.]
During the election Xenophon and his SA Best party pushed for a law that Ice users in South Australia will be forced into drug rehabilitation.
After early opinion polls indicated that SA Best could outperform the two main incumbent parties, the party ultimately contested 36 seats in the House of Assembly and put forward four candidates for the upper house. Opinion polling indicated a strong performance for the party was possible in at least 10 seats.
Key seats for SA Best
The table lists, according to The Poll Bludger website and based on the Nick Xenophon Team's Senate vote performance at the 2016 federal election, the strongest SA Best seats.
Though most of the listed seats are safe Liberal seats, a third party or candidate with a substantial vote was believed to be more likely to be successful in a traditionally safe seat than a marginal seat due to it being easier to out-poll the comparatively low primary vote of the seat's traditionally uncompetitive major party, usually before but occasionally after the distribution of preferences (see 2009 Frome state by-election). If the third party attracts enough first preference votes away from the dominant party, then it is possible that the preferences of voters for the second traditional party will assist the new party's candidate to overtake and therefore defeat the incumbent on the two-candidate-preferred

vote (rather than the normally pivotal two-party-preferred vote). According to ''The Poll Bludger'', Nick Xenophon's SA Best candidates "will stand an excellent chance in any seat where they are able to outpoll one or other major party, whose voters will overwhelmingly place them higher than the candidate of the rival major party. In that circumstance, the more strongly performing major party candidate will be in serious trouble unless their own primary vote approaches 50%, which will be difficult to achieve in circumstances where approaching a quarter of the vote has gone to SA Best."[
Analysis in December 2017 from polling company Essential Research found SA Best preference flows of 60/40 to Liberal/Labor, indicating that the substantial third party presence of SA Best is eating in to the Liberal vote somewhat greater than the Labor vote.][
Ultimately, the SA Best party failed to secure any lower house seats, although there was a close contest on preferences in the seat of Heysen, which is based in the ]Adelaide Hills

, where the final two party result was Liberal 51.2% to SA Best 48.2%. SA Best party leader Xenophon failed to win the seat of Hartley after finishing second on first preferences with 24.9%. The seat was retained by the Liberals after Xenophon was eliminated from the 2 party count, after falling between the Labor candidate, due to the preference redistributions from the other 4 candidates which totalled about 10% of the vote. The party came second on primary votes in ten seats; the strongest results were in Chaffey, Finniss, Hartley, Heysen and Taylor where the party received over 24%.
SA Best did, however, secure two upper house positions in the South Australian Legislative Council

, with the successful election of Connie Bonaros, the campaign manager, and Frank Pangallo, Xenophon's former media advisor.
Following the election, NXT Senator Stirling Griff claimed that polling indicated a 5% drop in SA Best's vote as a direct result of negative advertisements by two major parties as well as the Australian Hotels Association (AHA). He also claimed paternity for an election ad that had been described as "wacky, cheesy" and that that ad actually led to a polling bump for SA Best.

The Electoral (Miscellaneous) Amendment Act 2013 introduced set dates for writs for general elections in South Australia. The writ sets the dates for the close of the electoral roll and the close of nominations for an election. The Electoral Act 1985 requires that, for a general election, the writ be issued 28 days before the date fixed for polling (S47(2a)) and the electoral roll be closed at 12 noon, six days after the issue of the writ (S48(3(a)(i)).

The proposed changes in the draft redistribution contained significant boundary redrawing. Seven seats would be renamed − Ashford would become Badcoe, Mitchell would become Black

, Goyder would become Narungga, while Little Para would once again become Elizabeth. In two-party terms since the previous election, the seats of Mawson and Elder would become notionally Liberal seats, while Hurtle Vale would become a notionally Labor seat. Mawson in the outer southern suburbs would geographically change the most, stretching along the coast right through to as far as and including Kangaroo Island

. Hurtle Vale's margin change of 9 percent would be the largest in the state, with Mawson to change 8.3 percent and King to change 8 percent.[
Upon the release of the draft redistribution, Liberal MP Rachel Sanderson organised the mass distribution of a ]pro forma

, which in the draft would have been transferred to neighbouring Torrens. Sanderson's position however was at odds with her own party's submission which in fact agreed with the commission that Walkerville should be transferred to Torrens. Under the commission's draft proposal, the Liberal margin in Adelaide would have been reduced from 2.4 percent to 0.6 percent, but would have also resulted in the Labor margin in Torrens reduced from 3.5 percent to 1.1 percent. Of a record 130 total submissions received in response to the draft redistribution, about 100 (over three quarters of all submissions) were from Walkerville and Gilberton. As a result, the commission reversed the draft decision in the final publication.
Along with other various alterations in the final publication released in December 2016, in addition to Hurtle Vale becoming a notionally Labor seat and Mawson and Elder becoming notionally Liberal seats in the draft redistribution, the final redistribution additionally turned Newland and the bellwether

of Colton in to notionally Liberal seats. These further changes provide a 27 Liberal−20 Labor notional seat count in two-party terms, a net change of three seats from Labor to Liberal since the previous election.[
Labor objected to the commission's interpretation of the fairness requirements and appealed against it to the ]Supreme Court of South Australia

in accordance with the provisions of the Constitution Act 1934 (SA). Labor sought to have the redistribution order quashed and have the Boundaries Commission make a fresh redistribution. The Grounds of Appeal were stated to relate to the Commission's interpretation of section 77 relating to the number of electors in each electoral district, with the redistribution reducing the number of voters in rural seats and increasing the number of voters in metropolitan seats, though still within the one vote, one value 10 percent tolerance. The Supreme Court appeal was rejected on 10 March 2017. Labor considered but decided against an appeal to the High Court.

. The EDBC is the only redistribution authority in Australia that is required to examine voting patterns in drawing electoral boundaries, and in doing so, assume that the proportion of each party's vote in the declaration vote (postal, pre-poll and absent votes) is evenly distributed across the whole of each former electorate. Antony Green's margin estimates are more accurately calculated using declaration votes from the redistributed polling booths.

The July to September 2014 Newspoll saw Labor leading the Liberals on the two-party preferred (2PP) vote for the first time since 2009. The October to December 2015 Newspoll saw Marshall's leadership approval rating plummet 11 points to 30 percent, the equal lowest Newspoll approval rating in history for a South Australian Opposition Leader since Dale Baker in 1990.[
