Do Australian immigrants only look at undergraduate majors when applying for degree certification (EA)?

Australia should not agree with your domestic undergraduate major, although your major is on the list of degree certification. You can apply for EA yourself, but you need to complete three papers to prove that you are a qualified environmental engineer.

Some master's degrees are also on the list of EA certification for your major of postgraduate study in Australia. You should find out whether the major of the university you are applying for is on the list of EA certification.

You must need EA when you immigrate.

Whether undergraduate or graduate students apply for EA, as long as EA can come down, they can apply for independent immigration with their academic qualifications.
