I think that is very likely,,
For Monash university, it depends on which campus.
If the campus is in rural area, then it is difficult to get a part time job.
If it is in an urban setting , then it is easier..
bbs.taisha.org has a subforum for studying in australia. go to that forum and post your questions, those who have been to monash or MQ will give you more specific information
May you be mindful in all your endeavors
