During COVID, the RBA started quantitative easing - for the first time in Australia (in a significant way at least), my sources say this was ~$300,000,000,000 of bonds bought (300b of public debt)
My understanding is that this 300b was new money (created by fiat, by the RBA). Since our annual expenditure servicing our debt is now the same as the annual cost of Medicare (and growing) why can't the RBA simply cancel the debt?
$300,000,000 isn't 300 billion, its only 300 million. Three hundred billion is $300,000,000,000.
Edit, oh, wait, you slipped a stray extra 0 on. That's still only 3 billion.
