He has entered the country legally. Has he lied on an affidavit?Not in the slightest. If he has entered the country illegally given the mistakes on his Visa application that is relevant. If he has lied in an affidavit that's jailable. It seems both have happened going by media reports. I'm not a tennis fan so don't give a stuff whether he stays or goes. But anyone else who lied in those ways (if that is true) would have their visa revoked so I think he is in trouble. The fact he doesn't deny doing a media interview and photo shoot knowing he was covid positive is disgusting and says a lot about the bloke. Now there are questions over whether or not he knew he was positive when he did the public appearance the day before with kids. I think he is in trouble.
His decision to do the photo shoot is bad, no doubt, but was it criminal? Plenty of s**t people travel to Australia. Doesn't mean you have the grounds to deport them.
