I am married over 7 years, with a 5 year-old son. My wife had an undiagnosed mental health issue. The GP once referred her to a psychiatrist and she went only twice but later on denied to visit that psychiatrist further. She went to her parents' place and came back after 2 months. She was fine for a few days, but then the same issue returned. As a result, I talked to her parents, who advised me to send her back, and if needed, they would take her to the doctor. Initially, I agreed to let my son to go with my wife for a short period of time, however once she was there, they stopped my communication with my wife and son. They have been living there for the last 12 months and it was a non Hague Convention country. Once the situation had gone really bad, her parents were planning on an involuntary admission, but she somehow found out and flew back to Australia but in different state. In the meantime, I have filed for an airport watch list, but she got angry and filed for an intervention order with full of lies. The problem is if any doctor just assesses her without knowing any previous history, they wouldn't find anything about her illness. She is living in a different state and trying to enrol my son into the school. She is looking for a job too, to settle down there. What are my options under Family Law to bring them back to my own state?
