Which is better to immigrate to Sydney, Melbourne or Los Angeles?

Of course, Australia is good, and the welfare in the United States is very poor, so it can't be compared with Australia. Take medical care as an example. Needless to say, American medical insurance is terrible. Australia's medical insurance is basically all-inclusive, all hospital fees are free, and some drugs are discounted.

Compared with Sydney, Melbourne is better, and the livable city Melbourne ranks first in the world.
