Today, a Melbourne court will hear arguments on whether the unvaccinated tennis star, Novak Djokovic, should be allowed into the country to play in next week's Australian Open, or whether he should be deported.
The Australian government had moved to have the hearing delayed until Wednesday, but that was rejected by a judge overnight.
Meanwhile, in Djokovic's home country Serbia, supporters have been rallying in the streets every day to show solidarity.
The BBC's Guy De Launey spoke to Sarah Robson from Serbia's capital, Belgrade.
