When the UK last year implemented a similar age verification system for adult sites, in the first week of it launching, four of the top five downloaded apps in the Apple app store were virtual private network (VPN) apps, with Proton reporting an 1,800% increase in downloads of its VPN app.

VPNs allow users to appear to sites that they’re in another location, which could bypass age check requirements in Australia.

I don’t have data on VPN signups in Australia, but I see that Google searches for VPNs have abruptly spiked among Australians.

EDIT: Might need to reload the page a few times if the graph doesn’t show up. It’s giving me an error about half the time.
