It means Nadal, Djokovic and Dominic Thiem will play against one another at Memorial Park while Ashleigh Barty, Simona Halep and Naomi Osaka are likely to face off in the women’s event.
But that doesn’t leave them much time to head down to Melbourne for the start of the ATP Cup on February 1.
Djokovic helped lead Serbia to victory in the inaugural ATP Cup last year, beating Nadal’s Spain in the final.
The tournament will see 12 countries face off and every top-15 star except for Roger Federer are set to compete.
