Is it troublesome for 5 million immigrants in Australia to get a green card?

The latest "major investor" visa for China to immigrate to Australia requires the applicant to invest at least 5 million Australian dollars, so he can skip the requirements of skilled immigrants such as English level, age and scoring system, and only need to live in Australia for 40 days every year for four years to obtain permanent resident status. And such applicants are likely to buy a house to live in, and even use the extra funds to invest in commercial real estate.
