Oh, you know what? I misread the statistics site and read NSW's rate as the entire country's. It's actually around one in 100

https://immunisationcoalition.org.au/influenza-statistics/

There have been 254,485 notifications of laboratory confirmed influenza reported to the NNDSS in the year to 9 November 2026.

With a population of 27 million, that's one in 100.

The reason it's 1 in 100 in this country, and 1 in 8 worldwide, is because of our great healthcare system and protective social determinants of health, like nutrition and daily hygiene.

Since this is Lemmy, I assumed most people commenting would be from rich countries like Australia, so an Australian statistic would have better applicability to this population than a global statistic.
