1999 Australian Open

The 1999 Australian Open was a tennis tournament played on outdoor hard courts at Melbourne Park in Melbourne in Victoria in Australia. It was the 87th edition of the Australian Open and was held from 18 through 31 January 1999. This was the first Grand Slam of the calendar year. Total attendance for the event reached 391,504.

In the singles competition, Petr Korda and Martina Hingis were the defending champions. Korda was unseeded at this tournament and was eliminated in the third round by American 15th seed Todd Martin. This loss resulted in him falling down the rankings from 20th to 76th. Later in July, Korda was ordered a suspension from tennis by the ITF after testing positive for nandrolone at Wimbledon last year. Yevgeny Kafelnikov, on the other hand, ended up becoming the men's champion, defeating surprise finalist Swede Thomas Enqvist, 4–6, 6–0, 6–3, 7–6(7–1). With this win, Kafelnikov became the first Russian, male or female, to win an Australian Open title. In the women's singles, two-time defending champion Martina Hingis successfully defended her title, defeating another surprise finalist in Frenchwoman Amélie Mauresmo, 6–2, 6–3. This win allowed Hingis to join Margaret Court, Evonne Goolagong Cawley, Steffi Graf and Monica Seles as the only women to have won three consecutive Australian Open titles. Amélie Mauresmo would later become the World No. 1 in 2004, and despite being one of the top players of the early-to-mid 2000s, this would be her only Grand Slam final until the 2006 Australian Open, which she won.

In doubles, the defending champions were Jonas Björkman and Jacco Eltingh for the men's, Martina Hingis and Mirjana Lučić for the women's, and Venus Williams and Justin Gimelstob for the mixed. Eltingh did not participate at this year's Australian Open, leaving Björkman to team up with Australia's Patrick Rafter. Rafter and Björkman later won the title, defeating the Indian first seeds Mahesh Bhupathi and Leander Paes, 6–3, 4–6, 6–4, 6–7(10–12), 6–4. Hingis and Lučić also separated, with Hingis teaming up with Anna Kournikova and Lučić teaming up with Mary Pierce. Lučić and Pierce fell in the first round, but Hingis and Kournikova went on to win, by defeating first seeds Lindsay Davenport and Natasha Zvereva at the final, 7–5, 6–3. The mixed doubles competition saw Williams and Gimelstob not competing, and none of the seeds reaching past the second round. In the end, the South African team of Mariaan de Swardt and David Adams won, defeating Williams' sister Serena and her partner Max Mirnyi in the final, 6–4, 4–6, 7–6(7–5).

The Juniors Competition saw the first ever junior double, with Kristian Pless and Virginie Razzano both winning their respective singles and doubles titles. Pless defeated Mikhail Youzhny, 6–4, 6–3, in the singles before teaming up with Jürgen Melzer to defeat the Czech team of Ladislav Chramosta and Michal Navrátil, 6–7, 6–3, 6–0, in the doubles. Razzano defeated Katarína Bašternáková, 6–1, 6–1, in the singles final and teamed up Eleni Daniilidou to defeat South Africans Natalie Grandin and Nicole Rencken once again with a, 6–1, 6–1, score. The last time a boy won both the singles and doubles title at a Grand Slam was Roger Federer at the previous year's Wimbledon, while the last girl was Cara Black at the Wimbledon the year before. Julien Jeanpierre and Mirjana Lučić were the last players to win Australian Open Junior singles and doubles titles in the same year; in 1998 and 1997 respectively.
