I am now a permanent resident of Italy. Is it easier to immigrate to Australia than to live permanently in China?

Italian permanent residence applies for permanent residence in Australia, and the conditions are the same as others, nothing special.

The only advantage is that instead of applying for permanent residence in Australia, you can apply for other visas, such as work visas and student visas.

Italian is a low-risk country, while Chinese mainland is a high-risk country (referring to immigration tendency).

For example: 4 17 visa. China people can't apply, but Italians can.

See the website of the Australian Immigration Bureau: http://www.immi.gov.au/visitors/working-holiday/visa-options.htm.

This means that it may be easier for you to earn points for permanent residence in China than ordinary people.

But after all, you just live in Italy forever, and I'm not sure about the difference between you and Italians. You can check more online.
