Are you hoping to move closer to Clayton campus, or stay in regional Victoria and only come in when you have compulsory face-to-face classes e.g. a practical? If you’re doing the former, I’d say it’s not bad, with the occasional hit and miss (typically works or something happening on the line). If you’re doing the latter, you might find that quite rough.
I’d suggest having a read of the Public Transport (Clayton campus) section of the
Monash Uni New Student thread by VanillaRice to get an idea of what it’d be like for metro Melbourne students.
Note: I did all my tertiary education pre-COVID. Now with online learning being a bigger thing, you might be able to find some flexibility and only come in occasionally for a compulsory onsite class, but this largely depends on what course you’re taking. For example, nursing and medicine students might find themselves making the trip down often vs. a humanities/ arts student.
