First, the increase in the McD burger price over those 7.5 years constitutes around 4% p.a. That's certainly not great, and twice the usual inflation target, but not catastrophic.
Second, there was no "out-of-control" money printing in Australia, see [1].
Third, if there was out-of-control money printing (and there was some loose monetary policy, and at the zero lower bound this does involve expansion of the central bank balance sheet, ie QE), it was after the GFC in 2007 [2]. However, there was no inflation for a decade and a half after.
But then, the pandemic and the Ukraine war hit. Now you had supply constraints (reduced production and logistics challenges) and also increased demand (due to fiscal easing (stimulus, subsidies) during the pandemic, and people "catching up" on spending afterwards). And then there was a short bout of inflation.
Why do people keep complaining about money printing if that's not the cause for inflation?
Fourth, you find extensive discussion of all these issues in utterly mainstream media.
