Point is his previous infection was early in 2021 so outside the window that would allow him an exemption to play at the AusOpen. He refuses to get vaxxed as we know, so very conveniently gets infected around Dec 16th, or at least tests positive on the 16th, but continues to attend events and travel to the EU and Spain.
Either he was infected but didn't care about masking or travelling, and didn't disclose he was infected when entering the EU, or he didn't get infected at all and made it all up to get the Australian exemption. My money is on the latter, but who knows.
