10 unique facts about 50 Open Era editions of the Australian Open

The Australian Open, played on hard court in Melbourne, starting on the third Monday of January is the first Grand Slam event of the calendar. But it hasn't always been this way. The tournament was played on grass till 1987 before shifting to hard court in 1988. Due to a scheduling change in the late 70s, the Australian Open was actually the last Grand Slam event on the tennis calendar for almost a decade (1977 to 1985).

Due to the general geographic remoteness of Australia, low prize money, and the event starting too close to the Christmas/New Year holiday period, many top players used to skip the tournament till 1982.

The 2019 edition of the Australian Open was the 50th edition of the tournament since tennis opened its doors to professionals in the summer of 1968. Novak Djokovic (7 titles), and Roger Federer (6 titles) are the two most successful players in the tournament, with each player featuring in the most number of Australian Open finals (7 apiece). On that note, let us have a look at 10 unique facts about 50 editions of the Australian Open held in the Open Era.
