Australia is introducing age checks for search engines like Google

And let's not even forget that maybe 50 to 100 years ago, "kids" could more commonly be married and have kids under this arbitrary limit of 18 years old and that did not make them crazier adults than what we have now. At that time, 20 was easily already mid life. Still take care to not compare with countries of today were kids are still able to marry young. These are usually retarded countries were kids are clearly forced and abused to do that.

Looks like the ruling gov still sees their citizens as such

It's worth reading this short piece about British conductor Sir Eugene Goossens who in the mid 1950s was conductor of the Sydney Symphony Orchestra and after a tour of the UK brought photographic material back to Australia that was deemed pornographic by Australian Customs. He was arrested, he resigned and his life was ruined for something many nowadays wouldn't give a second thought about (although different, the tragedy has shades about it reminiscent of what happened to Oscar Wilde): https://www.ebsco.com/research-starters/law/british-conducto...

The Goossens incident was a classic instance of Australian conservatism—conservative values—in action.

It happened some years before my classroom incident but Australian Society's views were essentially still static, not much had changed by then.

That said, things did change and by the mid 1970s Australia had largely caught up with the sexual revolution of the 1960s, nevertheless its society has always retained a high level of conservatism and conservative values about it.

The background behind these new internet regulations is both complex and nuanced. That they've managed to take hold and become law almost without so much as a squeak from the population is partly explained because of that risk averse conservatism but also as there's been no opposition to speak of. By and large, Australians do not complain enough when their politicians enact laws that are authoritarian and unjust. It's rare for Australians to take to the streets on mass and demonstrate. The last time I witnessed that was during the Vietnam demonstrations of the late '60s when a broad cross section of the population took to the streets—and guess what, the laws were changed, politicians actually took note (numbers really matter).

These days demonstrations are largely carried out by minority interests, politicians take little interest and not much happens, and the Establishment still gets its way. The population watches on with little interest and often takes the view that such 'radicals' ought to be off the streets.

The reasons for the population's complacency are too complex to cover here except to make the point again that the conservative nature of Australian society makes it easy for politicians to convince the population that authoritarian law is in Society's best interests. Likewise, politicians are easily convinced by vested interests to that effect for the same reasons.

The large migration of recent decades has brought with it additional complexity, it's changed Australian Society greatly. Migrants have brought both cultural and religious values with them many of which are traditionally conservative (but by nature very different to traditional Australian conservatism). Given migrant numbers, Australia is more conservative now than it was say 30/40 years ago but not to the extent it was in the 1950s.

Moreover, as cultural differences now exist across large sections of the population the Nation no longer speaks with one voice on many issues as it one did (politics back then was fought across a narrow spectrum of interests). These differences not only make governments even more suspicious of their citizenries they also enable power brokers and vested interests to more easily manipulate Government to have it change laws than would have been the situation decades ago when the Nation spoke more with one voice on many issues.

In recent years there have been multiple instances of successive Australian Governments having taken advantage of divided opinion across society to change laws—laws that effectively take power from the Citizenry and cede it to themselves. These privacy-busting authoritarian laws/regulations are now on the statutes simply because there was not enough opposition to them. It's another classic instance of united we stand divided we fall.

And yeah, majority of Chinese people use a VPN to get around similar blocks.
