The whole premise of this supposed huge number of undetected infected is unsupported garbage.
A person is infected with Covid-19, 5 to 14 days later they either show symptoms or they are asymptomatic, in either case they are still able to shed the Virus and infect others. IE They are carriers whether showing symptoms or not, the disease in those who show symptoms persists for another 2-3 weeks as they become ill with it, and there is nothing at all to suggest that those who do not show symptoms are in any way less able to carry and shed the Virus to others. Those who recover from the Virus are still shedding the Virus after they recover for anywhere up to 2 weeks after they are out of the critical condition. This is why even those who do not show symptoms are required to practice self isolation for at least two weeks.
So all up, from the time of contracting the Virus up until one is deemed safe to come out of self isolation can be anywhere from 5-7 weeks even for someone who is non symptomatic. IE you are still carrying the Virus in your system if you have contracted it even despite being asymptomatic.
Over 90% of test's are negative apparently with over 350,000 test's carried out so far yet only just over 6000 being found positive.
IF there were a large pool of Australians not showing symptoms of Covid-19 yet still carrying it as asymptomatic there would be far more people being found Positive for it than we have done so far. Even four to five weeks is plenty of time to pick up anyone carrying the Virus without showing any symptoms out of the number so far tested.
