Well, we know he didn’t have a valid medical exemption, according to the government website - it listed what’s NOT a valid medical exemption and in this list included previously having caught the virus - and this was the most essential criteria, if he was to enter the country, and we know he lied on his visa application form, somehow forgetting his recent travel itinerary in the weeks before arriving in Australia, and we know that he caught covid but acted as if he was not only above the law - which in this matter, he broke - but above nature too, by continuing with his schedule in full view of everybody, regardless of whether or not they caught it from him.
So I hardly think he’s blameless - in fact I think he had no grounds to enter the country, and didn’t help himself at all…
