dino looking at the most reliable ATAR calculators (imo), Monash and Atar notes, you'll likely need a raw 47 in two subjects, a 40 raw in chem and a raw 46 in one subject. Note that these raw study scores are likely the minimum you'll need to get a 99.
However, I believe that Monash law requires a 97.1, so you have a tiny bit of leway.
At the end of the day, all you can do is your absolute best, but by your current results it looks like you're doing well, keep it up.
