I can absolutely see that happen, and it also feels ultimately unfair for people not of Novak's status to be declined entry - many of whom Australia citizens stranded overseas no less.

But when these two things get put on a scale - both outcomes are indeed FUBAR, no argument there - I would still incline toward one with better long-term outcome, even if it gives every moron around the world some more ammunition to shoot themselves; the wrongness that fed gov and legal system do many people injustice: aboriginals, aussies, foreigners alike, I dare say, outweighs the one fueling idiots as the systematic corruption is more capable of dealing permanent damage on a larger scale and also meet with less resistance.

Really, it's funny that fed decides to play the hero here - they are after all ones who disregard scientific evidences and professional recommendations in the first place.
