IF Djokovic was led to believe by TA/Tiley that a Covid positive within 6 months would suffice and IF he actually has been Covid positive in that time, then I have some sympathy for him. I don’t think it’s especially unreasonable to expect TA/Craig Tiley to give accurate, up-to-date guidance and for him to rely upon that without necessarily questioning its veracity. But that’s where my sympathies stop. If the Australian state/government has mandated entry requirements and he hasn’t met those - regardless of whether a few other players have snuck through - then he has no business being in the country, even if he’s only there because of the incorrect advice from TA/Craig Tiley. His argument lies with them for misleading them, not the Australian state for refusing to honour the promise TA/Craig Tiley were seemingly never entitled to make, either to him or others. And no amount of others who have been allowed through, presumably in error, remedies that.
