Setting the scene
- Australia has a population of approximately 25,780,000.

Demographics and mortality risk of Covid-19 in Australia
The average age of death from Covid-19 in Australia (you would think an important statistic to identify which categories are at greater risk of mortality) is almost impossible to find and is not published by the Federal or State Governments as part of their routine reporting. However, it has previously been reported as approximately 85. The median age at death from Covid-19 in Australia is approximately 84.
