Novak Djokovic expressed a desire to concentrate on tennis, following claims of being "poisoned" during his detention in Melbourne.
In a recent magazine interview, he detailed health issues, citing high levels of lead and mercury from the food he consumed while detained.
At a pre-Australian Open news conference, Djokovic declined to provide specific evidence for his claims, emphasizing a wish to focus on the competition.
The Australian Border Force has not commented on the accusations, while experts consider the claims to be unusual.
Djokovic, a 10-time champion in Melbourne, reflected on the trauma felt upon returning to Australia following a contentious deportation in 2022.
