Happy "ask your mates at other universities to say something nice about your own university and vice versa in order to prop up the giant farce that is the completely unnecessary but highly profitable university "rankings" industry"-day, for all the simps that celebrate it.

I suspect this is sensationalist nonsense. It is a projection not a forecast apparently based on linear extrapolation with no mention of effect of immigration (hence children, grandchildren etc etc of immigrants) perpetuating some level of population floor.

The population of New South Wales is projected to increase from 8.1 million in 2021 to
10.1 million in 2041, despite
a low assumed fertility rate.

The growth may be seen as the product of fertility being above the MIGRATION-ADJUSTED replacement level.

Yes I remember examples from when my kids were in day care. There have also been increases in childlessness (although some of this is just more overseas students, working holidaymakers etc getting counted in the population).
