The event's full field was announced on Thursday with world number four Agnieszka Radwanska, runner-up at Wimbledon last season, heading the list.
Three women with Grand Slam titles on their CV - Li Na, Petra Kvitova and Sam Stosur - will also compete, while the other members of the top 10 heading to Sydney are former world number one Caroline Wozniacki, French Open runner-up Sara Errani and Angelique Kerber.
However, the world's top three - Victoria Azarenka, Maria Sharapova and Serena Williams - have opted not to play. They will instead complete their Australian Open preparations the week before in Brisbane.
The men's draw is led by Jo-Wilfried Tsonga, with Richard Gasquet the other top-10 star signed to play.
Defending champion Jarkko Nieminen and Australian number one Marinko Matosevic - recently voted the ATP's most improved player - were among those to have their entry confirmed on Thursday.
Tournament director Craig Watson said: "We are bringing together an incredible group of players to compete in Sydney next month.
"We are thrilled to have nine top 10 players, Australia's number one male and female and Grand Slam champions in the outstanding field.
"The 2013 tournament will offer fans a great opportunity to come and witness so many of the world's best tennis players in action right here in Sydney."
