You were lucky at mediation.
Speaking as someone who took an OC to mediation (where agreements are not binding) and the NCAT (where in theory judgements are binding), I was let down in both cases.
At mediation the OC agreed to something and soon after ignored it.
I then went to NCAT where they were ordered to do the same thing, and do it within 2 months, but they ignored that order. Many months after the deadline set by NCAT, they finally did a ham-fisted attempt which had to be redone thereafter.
