I’m not sure how much you can actually glean from this Australian Bureau of Statistics data (taken from this recent New Geography article):
The data was collected on August 20, 2021 and, at that time, there were still a number of pandemic lockdowns in place. But consider the fact that during the last census (2016), Sydney’s “work @ home” share was only 4.9% and that its transit share was 26.2%.
Where Sydney is sitting today is obviously somewhere between where it was in 2016 and where it was in 2021. Who knows where exactly things stabilize — that is largely unknowable — but at least I got to use “Sydneysider” in a blog post title.
