Yes, Mr. Racket Novak, you are a spoiled brat.
You're hardly the only one among professional sports stars. Indeed the far more-rare is the humble human who recognizes that he or she has a gift, said gift requires a lot of hard work to fully express, they do so but beyond their particular prowess in whatever discipline they have that's the end of it in terms of "special-ness"; beyond that boundary of skill they're just a sack of meat like the rest of us.
It is now reported that Novak was both deported from Australia and drew a three-year ban on re-entry, both for lying on his visa application. In short he thought he was special and though not an Australian citizen and thus not entitled to be there at all he could BS his way into the nation and do it "his way" instead of theirs.
He got caught.
The simple reality of travel to nations where you are not a citizen is that you are a guest. You have no right to be there at all. Your entrance and travel are at the whim and pleasure of the nation and government in question -- period. You're no more-special than anyone else, no matter how good you are at this or that.
That's the beginning and end of discussion.
Yes, I know he's brought millions (or even hundreds of millions) of dollars into the nation with his skillset and its attractive power to sell advertising and glue eyeballs to television sets. So what? The nation of Australia has the right to weigh the value of said "contributions" to their economy however it wishes, and if their determination is that said value is insufficient to declare you "special" that's the end of it.
When it comes to a citizen things are different; there you have every reason in a civilized nation to expect that whatever rights and privileges extended to all citizens will be respected in your individual case as well, since you are a citizen. But if you're not a citizen this is simply not true any more than you have a right to come into my personal home and then tell me how I must treat you and what you're entitled to once there when I'm the one holding the pink slip and you are a nothing more than a guest.
Yes, the pandemic has led to a dumpster fire wave of stupidity by governments all over the world, including ours right here in the United States. That changes nothing.
I've traveled internationally and used my US Passport -- less than many, more than some. If and when the stupid ends I may do it again. But there's one thing that should always be kept in mind when traveling internationally: No matter the issue, no matter your personal beliefs you are a guest and you have no right to get involved in any way, shape or form in whatever political environment is present there or whatever politically-related issue(s) may be in the place you are visiting, nor are you entitled to exceed the parameters of behavior you claimed constituted your purpose when you entered the nation.
It's none of your damned business, you have no representation and no right to exert even that which we denote in the US as "free speech" say much less anything more.
If you have reason to believe that disclosure of something they specifically asked about would lead you to be denied entry then you're lying when you conceal it and that standing alone is enough for them to turn you back and ban you from entry in the future. People have been denied entry to or expelled from other nations for something as simple as a DUI or concealed intent to engage in some sort of commercial activity and it is that nation's absolute right to do so. It doesn't matter whether you agree with their policies or not -- that's immaterial. It's their nation, not yours, just as I assert when it comes to illegal entry here it's our nation, not theirs, and we have every right to condition said entry or even stop it by whatever means are necessary should we so choose.
The bottom line is simple: Whatever government-conveyed "rights" you may have only extend as far as your citizenship and end at your nation's border. When you voluntarily enter another nation you do so at their pleasure and you follow their rules, whatever they may be. If you're not willing to do so then stay out.
That's the beginning and end of it and IMHO Novak earned and deserves his ban.
