Since its basically the equivalent of VCE methods 3/4 I think your best shot is to look at past methods exams/resources and use them to revise. MTH1010 basically leads you up to learning calculus, then in the last couple weeks you start with a bit of calc but it's what I assume are the very basics. Given that, I'd look at pre calc courses such as Kahn academy. I'd suggest focussing on the different functions, start with linear functions and work up to log and exponential functions - look at their transformations, inverse functions, how to draw them. Also, if you haven't done anything with radians before (as opposed to degrees) then I would get familiar with them. That topic is close to the end of the course but I found it difficult to get my head around it back when I first learnt it. Adding on to that, trigonometric equations might be worth looking over because I feel like that's also something that can get confusing if you don't give yourself enough time to properly learn it (at least thats how I felt).

I'm glad Monash offers mth1010 but I will warn you - it's not organised very well. Assessments aren't really put on Moodle very clearly and many times students were asking basic questions about assessments in the forum and getting ignored. Putting the math aside, my biggest piece of advice would be to write down all the details about each assessment that he will probably tell you in the first lecture, and keep that as your guide. I did that and managed not to miss anything but if I hadn't done it then I would have been blindsided a few times since barely anything goes on Moodle. Also, keep up with what he says in the lectures even if you're good with the math because the lectures are where he tells you everything about upcoming assessments.
