While the OP is more wrong than right they aren't completely incorrect.

I'm in Australia.

GCP has 2 regions in Australia, Sydney and Melbourne. The Sydney region is in the Equinox DC. Not sure where the Melbourne one is but it isn't a Google-owned facility.

You can see this by comparing Google's Data Center list: https://www.google.com/about/datacenters/locations/ vs their Cloud Location list https://cloud.google.com/about/locations#asia-pacific

Note that the Cloud Locations aren't just "edge": they offer hosting, GPUs etc etc at these locations.
