Melbourne, Australia (AP)—The Australian Open is increasing its prize money by $3 million to bring overall player compensation to $31 million next year.

In keeping with player demands to see a larger slice of Grand Slam revenues, all four of the sport's Grand Slam tournaments have greatly increased their prize money in the past two years.

Wimbledon now offers about $36.5 million, while the U.S. Open increased its purse to $34.3 million and the French Open went up to $29.7 million.

Australian Open organizers did not break down the prize money awarded per round at their launch Wednesday for the Jan. 13-26 tournament, but men and women will receive equal amounts as in previous years.

Novak Djokovic and Victoria Azarenka are the defending champions at Melbourne Park.
