Class Action Outcome

Hi all,
I'm trying to figure out if this is a decent entry point and so it is crucial to have an opinion about the class action result.
Unfortunately, I have no experience with class action proceedings of this sort in Australia.

I was hoping someone could point me to previous class actions that already concluded and kind of present me with a range of what can happen - Can this be settled for $10M, $20M... $50M?? If this goes to court what can be ruled against the company?

If someone with legal experience can help that would be awesome!

Obviously, there's a lot of speculation and almost anything can happen but would love to get some different points of view.

Thanks!
