The 108th edition of the Australian Open begins on Monday as the world's best tennis players battle it out at the first grand slam of 2020.

Novak Djokovic and Naomi Osaka will return to defend the titles they won last year, adding to the event's storied history.

The pair will face stiff competition from stacked fields in the men's and women's draw as a host of players seek glory in Melbourne.

To whet your appetite for the forthcoming feast of tennis, here is a selection of the best Opta facts related to the Australian Open.

- The last three years have seen the 12 women's grand slam tournaments being won by 10 different players; only Simona Halep and Osaka have won twice in that span.

- Djokovic won his seventh Australian Open title in 2019, the most of any male player in the history of the tournament. He has won the event every time he has reached the semi-finals.

- Of the last 14 editions of the Australian Open, 12 have been won by either Djokovic (7) or Roger Federer (5) – Rafael Nadal (2009) and Stan Wawrinka (2014) are the only other winners in that period.

- Victoria Azarenka (2012, 2013), Serena Williams (2009, 2010) and Jennifer Capriati (2001, 2002) are the only women to have won successive titles at the Australian Open since 2000.

- Federer won his sixth Australian Open title in 2018, 14 years after his first win at the event; no player has won multiple Australian Open titles over a longer period in the Open Era. It is his last win in a grand slam tournament to date.
