It's not being done for the indigenous people
Like every other decision of consequence in the wide brown land of Oz, it was done by, and for the miners.
And BTW- this virus is officially Cov-SARS-2, not 'Coronavirus'. After considerable analysis, the scientists decided it was a second Severe Acute Respiratroy Syndrome, just like the last one.

SARS 1 was 15 years ago, lots of time to get prepared...
