Austrlian Open's organization revealed that the reasoning for Djokovic receiving the exemption will remain private because "the personal information of any applicant is redacted to ensure the independence of the process."
Earlier in January, the Victorian government released a statement regarding the tournament's exemption policy and said that it has a "two-stage independent process" in order to verify if any player has "a genuine medical condition that meets the criteria for an exemption." Clearly, they decided that Djokovic does.

Novak is not a criminal, sign this petition if you believe he need to be released from the Airport where he is blocked in a room with two policemen outside and they shall let him play the Austrlian Open, because he flew down there only when they have given him the vaccine exemption. 

Other 5 tennis players have been exempted and allowed to enter Australia with the same reason, and they are all already training at Melbourne’s tennis park without issue, so the special rules are used with Djokovic?! Not the opposite….That is an organized trap to create the monster and humiliate him internationally.
