Wherever it has happened, genocide and destruction of culture results in survivors who are more prone to disease. This is true for the first inhabitants of Australia, who as a group suffer high incidence of various avoidable diseases.
Fortunately for them, the governments have largely ignored them during the current pandemic, so they organised themselves without paternalistic control. The result: NO ABORIGINAL DEATHS and a very low rate of infection compared to other Australians. This is despite the fact that most Aborigines live in cities.
Perhaps those all so know-it-all politicians can learn from this, and pass self-determination on every issue to the people themselves.
