Hi,
I am a Murdoch University student and have no problems landing a job. Including me, there are 3 Murdoch graduates in my small firm. However, do take note that I'm studying Communications, not Commerce.
In my opinion, while RMIT may be more well-known, there is little difference compared to Murdoch University while applying for jobs locally. Both are Australian universities and offered by well-known private institutions.
At the end of the day, the cert only lands you the interview. Whether you're able to secure the job and advance your career depends on your knowledge application and character.
Do take note that Murdoch University courses are also offered by
SMF Institute of Higher Learning.
Why do you say "die die push myself into SIM and get a RMIT cert"? Are you very adverse to SIM?
