Australia is a communist country.
Seems to me this is just like the old Soviet Union as you have a gestapo Justice Department investigating protesters, even for parents protesting at school board meetings.
I think you should look in the mirror on which country is communist.
And, just a side comments, the USA has the same restrictions on unaccented foreigners entering the country as Australia. Unless you can your rules, Novak will not be able to play in the USA Open. Also you Federal vaccine mandate is worse than the one mandate we have here, which is aged home workers must be vaccinated. In the USA your Supreme Court just approved that all health care workers much be vaccinated.
