One way to use this graph is to ask "how many deaths would Oz have had in 2020-21 if they had the same death rate as another country?" To do this, multiply 1,744 x rate for country of comparison. Eg, if Oz was the UK, it would have had 1,744 x 33 = 57,552 XS deaths in that time.
While things are not great atm, in 2020-21, the collective actions of Dan Andrews & his team, along with other key Fed & State leaders, saved 10's of thousands of lives & averted many x more severe acute & chronic illnesses. These savings were sustained (a story for another day).
