It really does look like Australia tried to print its way out of the pandemic last year, and now its purchasing power hasn't kept up with other food, energy, and other inputs prices: https://tradingeconomics.com/australia/money-supply-m1 What should happen is a return of Bond Vigilantes: https://www.investopedia.com/bond-vigilante-6386194 , but if it doesn't, I'd wonder who is holding most of Australia's debt.
What are we meant to summarise from the first link? I see a chart of total money supply with the y axis starting at 1640B and going to 1700B. I.e basically no difference
The "they're just printing money" is probably too simple an explanation for CPI inflation, but stimulus payments the printing paid for may have eroded purchasing power.
