I agree that it would be good to start an EA group at Monash. Unfortunately, I am at the end of my Monash journey and have only been introduced to EA myself more recently and can't directly help in the starting of a society/club.
I think the best place to get information about starting an undergraduate student association at Monash is by contacting the Monash Student Association. Alternatively, if you're interested in also having a graduate student association then contact Monash Graduate Association. I could see there being a good amount of value in including graduate students as they may be able to tailor their research toward social impact or gain skills/experience that could help them have a greater impact in the future. However, my personal experience being a post-grad student is that I haven't had much time or inclination to be involved in student associations, but I don't know how generalisable that experience is. Perhaps starting with an undergraduate society should be the first step, then down the road, a post-grad component can be added once enough undergrads in the society get to that stage.
One additional idea I've had is that a Monash EA group could work with some of the organisations/groups within the Monash research infrastructure to provide pathways to summer research projects or post-graduate research/work. In particular, I have the Monash Data Futures Institute in mind as they appear to have a focus on doing socially impactful research and industry engagements. Things like sponsored events, Q&As and competitions come to mind
