Do I need a work permit to work in Australia, but I just want to work instead of studying abroad? I will now, but not very well.

You can work in the black market, but the salary is relatively low. It's okay to study at the age of 30, but there is something wrong with the visa. . It shouldn't be easy to renew your diploma. If you don't have any diploma in China, you will also study in a language class. However, if you don't have a diploma after a language class, you won't go to college. . . It is basically impossible for you to invest in immigration. . . On the whole, why did you come? . . I suggest you stay at home. . .
