My name is ***** ***** I am a NSW Solicitor. Thank you for your question, and will do my best to assist you with your question. Please understand this is not legal advise Please understand this is not legal advice but a guide to assist you.
You can make an application to the Family Court to have custody of your daughter and seek orders that your partner get treatment and any contact she has with the child she has to be clean.
In relation to the stealing if you did not give her your PIN and she stole it this is a criminal offence and you can report her to the police and seek to get the money she has stolen back.
These are really your only options. It is not going to be a simple task because you work away and you will have to try and find alternative work to make these orders work so you are able to look after your daughter.
I am sorry I cannot give you anything more positive.
