If you don't immigrate, is it worthwhile to go to Australia for graduate studies instead of accounting, and then return to China?

And accounting in Australia and China is not a system. If you study accounting there and come back, you can't work. And it is suggested that the landlord learn whatever he likes. As long as you major, you are not afraid to stay in Australia or return to China. Now the policy has been changed for half a year. Who knows what the new policy will be after graduation?
