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 Serb, 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 one of the final warm-up events 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.
“I am looking forward to experiencing the incredible support from the Australian fans and making this tournament one to remember.”
Meanwhile, Britain’s Emma Raducanu will begin her season at the Auckland Classic, which takes place from 30 December to 5 January.
Raducanu is on the entry list along with four-time major winner Naomi Osaka and home hope Lulu Sun, who reached the Wimbledon quarter-finals as a qualifier in July.
