I’m not in Australia, but in my mediation, we had a mediator, but my ex and I each had our own attorney on the outside that we consulted with between sessions.
You want her to have her own attorney when the time comes, someone who can tell her what is and isn’t reasonable. Basically their job was to let us know what a judge would probably decide if we went to court. If her expectations are unreasonable they will let her know.
Meanwhile, stop negotiating with her. Just say “I’ll discuss this with my attorney”. She’s trying to bully you into giving her everything she wants.
I think there are those kinds of mediations as well. Mostly I've seen don't have lawyers, some even forbid it. There are some run by trained family lawyers, but don't know if they give legal advice, or say anything if one party is completely unrealistic.
I might consider this option if things don't go anywhere.
I know where I stand. I paid for an asset assessment which makes a recommendation based on historical family law cases. And what that showed was aligned with what L said.
