What we know: Novak Djokovic and Australian Open timeline

(CNN) Novak Djokovic's Australian Open participation has provided a tumultuous backdrop to the tournament. The Serbian world No. 1 was detained in Australia last week over a visa and vaccination dispute, and on Tuesday released a lengthy statement addressing his movements in December 2020.

On Sunday, the tennis star left the country after a decision to cancel his visa for a second time was upheld.

Here is a timeline of all the events.
