Is Covidpositive travel possible?

I know a person who regularly transits our international border. He has had Covid19. He has been vaccinated.

Everytime he re-enters the country, he is required to isolate until a negative test is achieved. He is not allowed out of his hotel room while overseas (other than in Australia). What is the point of the vaccination if we don’t get our freedoms back?

The only reason for the above process is the assumption that he is carrying the virus. However, having had the disease and having had the vaccination, his body will kill the virus as the human body has done for millions of years. The virus mutates as every virus has the capability of doing. While there are different strains of this virus there are different strains of the flu and we adjust as we go along but we continue with our lives without constraint.

Is the Government going to continue to curtail our freedoms? Are we to forever live under a North Korea-esque regime with our freedoms forever controlled; or are we going to be able to start the journey back to normality with well defined positive steps forward?
