Having read over everything again, I’m finding several things difficult to understand.
What I’m having the most difficulty with is this this...Child Protection applied for supervision orders from the Children’s Court immediately after parenting orders were made in the Family Court for unsupervised time (last time). Child Protection have also put in great effort to have the supervision orders extended on a number of occasions (over several years?). You have a current 5 year FVIO. Child Protection are taking a hard line approach in that if the Family Court does not change the existing parenting orders to supervised time then they will again return to the Children’s Court and get a supervision order.
If this is their firm stance, they are without doubt the children are at risk of abuse without the orders being varied, and they could need to take it back to the Children’s Court anyway, why haven’t they sought (on their own accord...under s92A) to intervene in this case? They would be well aware they can seek to intervene.
Just seems counterproductive to me for CP to not want to at least be involved in this matter (where they can give direct evidence...even if the Court does not agree) when the idea of making you return to the Family Courts, in my understanding, was for there to be some form of finality...and they may have to take it back to Court anyway.
