... Does Google not have any data centers in Australia? (Granted, it isn't a given that Stadia might run out of those DCs, but with Borg, I don't see why they couldn't.)
That won't help. The connection to your house in Australia is using ancient copper lines that is all rotted out and stops working in the rain. In absolute best case conditions you could use this service but most of the country would struggle to stream 1080p reliably. The internet upgrade in Australia (NBN) is well known as the biggest government fuck up in the last 20 years.
All to upgrade them from 13Mbps to 17Mbps. Yes, I'm being serious.
