Novak Djokovic will play at the Brisbane International before he starts his bid to win a 25th Grand Slam at Melbourne's Australian Open in January.
The 37-year-old, a 10-time winner in Melbourne, is tied with Australian Margaret Court on a record 24 Grand Slam singles titles.
The Serbian, ranked seventh in the world, failed to add to his Grand Slam tally during a frustrating 2024.
The tournament in Brisbane, which runs from 29 December until 5 January, is the final event before the Australian Open begins on 12 January.
"I'm excited to be kicking off my Australian swing at the Brisbane International and to compete again at Pat Rafter Arena," said Djokovic.
