Carlos Alcaraz and Jannik Sinner will play an exhibition match in South Korea in January - just eight days before the start of the Australian Open.
The duo will meet in the Hyundai Card Super Match in Incheon on 10 January, with the Australian Open main draw getting under way in Melbourne on 18 January.
"For domestic tennis fans it will be the very first opportunity to see the two top-ranked players compete," tournament organisers said.
The pair, who met in three of the four Grand Slam finals in 2025, have won nine of the past 10 major titles between them.
