World #1 men’s tennis player Novak Djokovic’s appeal against the Australian Government’s deportation orders will proceed today in Melbourne. And there has been a thrilling rally of legal volleys over the weekend. First, Djokovic’s case to stay centres on his claim that he received a letter from the Department of Home Affairs on 1 January. That corro said his Australia Travel Declaration had been assessed, and his responses “indicated that he met the requirements for a quarantine-free arrival into Australia”. Yesterday, the Aussie Government said it will argue the letter offered no guarantee of entry. Also under scrutiny is Djokovic’s claim that he tested positive for COVID on 16 December because he made several maskless public appearances in the days afterwards. Tennis Australia’s Craig Tiley has broken his silence – he says they’ve been given conflicting advice by the state and federal governments. Game on.
