I agree that a country could easily go without Google Search, there's enough competitors in that space and they all do mostly the same thing that people would quickly switch with no issues.
The bigger problem would be Australians giving up YouTube, and to a lesser extent Android if Google Play Services is withdrawn.
There's no real competitor to YouTube, and especially during the virus where everyone's at home with nothing to do going without it would be a major pain point for many Australians. The country wouldn't collapse but it would be a big deal.
That's all assuming Google withdraws entirely from the country of course.
The tele providers would love that the play store went offline and get replacements. It is quite silly that they ship with Google Play as default actually I guess they are forced by Google.
Youtube on the other hand would be a caltural loss due to the network effect even if replacements would be plenty.
