Stan Wawrinka was the defending champion in men's singles but lost to four-time Australian Open champion Novak Djokovic in the semi-finals. Reigning women's champion Li Na did not defend her title, as she retired from professional tennis in September, 2014.Novak Djokovic won an Open Era record fifth men's singles crown by defeating Andy Murray in the final, and this was the third time they met each other in the final.Serena Williams won an Open Era record six women's singles championships by defeating Maria Sharapova in the final, and this was the second time they met each other in the final.
The tournament was run by the International Tennis Federation (ITF) and was part of the 2015 ATP World Tour and the 2015 WTA Tour calendars under the Grand Slam category. The tournament consisted of both men's and women's singles and doubles draws as well as a mixed doubles event. There were singles and doubles events for both boys and girls (players under 18), which was part of the Grade A category of tournaments, and also singles, doubles and quad events for men's and women's wheelchair tennis players as part of the NEC tour under the Grand Slam category.
The tournament was played on hard courts and took place over a series of 16 courts with Plexicushion surface, including the three main showcourts – Rod Laver Arena, Hisense Arena and Margaret Court Arena. The latter was unveiled with a capacity increase from 6,000 to 7,500 and also as the third Melbourne Park venue with fully operational retractable roof to make the Australian Open the first Grand Slam tournament with three such tennis stadiums. Partly due to the new roof, the 2015 event set an all-time attendance record of 703,899 fans. The cooler than normal temperatures may also have played a role.
Following a second round victory in Women's singles Canadian Eugenie Bouchard was approached by an interviewer, Ian Cohen, who cited tweets made by Bouchard the previous evening which complimented fellow competitor Serena Williams's on court attire. The interviewer, explaining that Williams "was kind enough to give us a twirl," asked Bouchard to offer her own twirl. Though Bouchard obliged, the request was met with criticism, with many accusing the interviewer of being sexist. The controversy was referred to by some media outlets as "twirlgate."Billie Jean King responded to the interview by saying "This is truly sexist. If you ask the women, you have to ask the guys to twirl as well." For her part, Bouchard said the request would not be sexist if men were asked to "flex their muscles and stuff." At least one media outlet pointed out that as part of a pre-tournament interview Rafael Nadal was asked to take off his shirt for the enjoyment of female fans.
The Australian Open total prize money for 2015 was increased to A$40,000,000, with men's and women's singles champions to receive a tournament-record 3.1 million Australian dollars reward.

This was the third time these two players met in the final. The other two times were in 2011 and 2013, when Djokovic won. This time would prove no different with Djokovic winning his fifth title, an Open Era record, to go along with his titles in 2008, 2011, 2012 and 2013. This victory was Djokovic's eighth grand slam title, tying him in the Open Era with Jimmy Connors, Ivan Lendl and Andre Agassi. This was Murray's fourth loss in the final of the Australian Open, three of them to Djokovic and one to Roger Federer in 2010.

This was her nineteenth career grand slam singles title, behind only Steffi Graf's twenty-two titles in the Open Era of tennis. This was Sharapova's third loss in the final; the other two losses were in 2012 to Victoria Azarenka and to Williams in 2007. Sharapova won the title in 2008.
