If we take the deathtoll from Sweden (lower than the USA, Spain, Italy, Belgium), Australia could have expected 15,000 deaths, adjusted for population. Less if we consider only excess deaths.
This is $33 million per life saved, typically for a person in their 80s.
Is this a good use of funds?
If this money was devoted instead to tackling climate change or domestic air pollution (basically the same thing), how many lives would have been saved and improved instead?
Its likely that the country could have been completely decarbonised - all coal power plants shutdown, urban wood burning banned and new efficient gas heaters and insulation subsidised, and all new vehicle sales replaced with electrics.
