VIC Family Law Final Orders - Change and Relocate Internationally

Hi, I'm hoping someone can help me as to which forms I need to use to change Final Orders, and to get consent to move internationally, along with how to find an Independent Children's Lawyer (ICL).
My Final Orders were made 12/8/2011.
By early September, my daughter ceased attending access as she was indecently assaulted by her biological father's father in law.
This went to trial last year and he was found not guilty on 6 charges of indecent assault on 2 of my daughters (one of which is now of age). All because their biological father lied under oath in support of his father in law and my daughters were expected to remember exact dates, some dating back 5 years prior.
My daughters have had no contact with their biological father since September 2011. No phone contact nothing.
My now 14 year old daughter has asked if she can take her biological father to court with her own representative to get permission to move to the USA.
In the Final Orders, there is a clause included " The parties do all things and sign all documents required to obtain Australian Passports for each child."......... I completed the application forms, and sent them via registered post along with a phone call to their biological father explaining he'll just have to sign them and send them back to me and i'll pay for them but I did not get
I am currently still paying my fee for our last Family Law Court adventure back in 2011. These proceedings were brought on because of my older daughter running away for 5 years, in which she hadn't disclosed she'd been assaulted until her younger sister did.
What forms would I need to gain full custody of my now 14 year old?
What forms would I need to ask for consent to move internationally?
How do I find an ICL for my daughter?
I refuse to attend any form of mediation if that is required, as when initial proceedings were in place it was not a successful mediation at all. Is there anything I need to do there?

 

Thankyou for your response.
Its been an unbelievable past 5 years with my children. As the detectives said when we went to trial, they were gobsmacked he got off and that just because he wasn't proven guilty does not mean that he didn't do it and with dealing with a "double whammy " of this occurring is really hard.
Given the fact that my children have had nothing to do with their biological father and a family report was completed when we attended back in 2011, the report was in favour of my children having the opportunity to move to the USA.
The biological father also threatened my youngest daughter on school grounds, when it came to light what had occurred. I attended a court to put in place an intervention order so she couldn't be approached at school, in which the judge refused, so I told him I wouldn't be adhering to the new Final Orders out of concern for my daughters safety and wellbeing.
In fact on the Final Order there was an injunction in place of his consumption of alcohol which was breeched when the incidents occurred.
I contacted Legal Aid yesterday and they stated that I would have to do a new application, and I could request the consent to relocate in that and request to have an ICL for my daughter? I am unsure of what form to use for this. And if need be I will attend Mediation but I know it wouldn't succeed due to the last events in Mediation.

 

Thankyou so much :O) Your advice is greatly appreciated :O)
