MELBOURNE, Australia — Novak Djokovic left Australia on Sunday evening after losing his final bid to avoid deportation and play in the Australian Open despite being unvaccinated for COVID-19. A court earlier unanimously dismissed the No. 1-ranked tennis player’s challenge to cancel his visa. Djokovic, a 34-year-old from Serbia, said he was “extremely disappointed” by the ruling but respected it. A masked Djokovic was photographed in an Melbourne airport lounge with two government officials in black uniforms.
