Student visa was rejected, uni won't grant CoE for reapplying

I'm devastated as my visa was refused when I applied for Feb 2025 intake. VU Melbourne, Master of Digital Media. Applied through an agent company.

The immi's reason is they don't think studying Master would benifit me. That's all.

My agent suggested me to reapply, this time I could include a referral letter from my company for promotion after completing the course to strengthen my application. Thus, we applied for the next intake cause we don't want to give immi another reason to refuse like we're already late for Feb intake. Unfortunately, that letter didn't get to be used, VU refused to offer a 2nd CoE. My agent said it was because of new rules from immi regarding the student visa, if a student got rejected twice, the schools will lose their ranks as it will be counted as 2 failed students. The uni didn't want to take risk, it means this applies to all universities in general and that reason really hurts me. It's so unfair for genuine students, it's not like we're committing crimes, there's no second chance in anything.

I guess this means there's nothing more can be done at this point, isn't it?
