When the laws come in, many Australians will get VPNs rather than provide ID to random websites. If social media sites are compelled block VPNs, is that technically achievable/viable? Cloud providers and VPN services have predictable IP ranges, so are easily blocked (/majorly inconvenienced) by sites motivated to do so. But social media companies might not want to block VPNs since a lot of legitimate traffic comes through them (e.g. people anywhere in the world who simply wish to have that extra layer of privacy from their ISP and wifi owner). Are there VPN strategies that will allow an Australian to reliably access social media as though their traffic is coming from another country? I also guess Australians who try this might have to access social media sites via a browser on their phone (as opposed to native app). Asking for a friend, of course.
