My wife and I are now going through a divorce, and we have a 5-year-old son. After getting a divorce, my wife wants to go Australia to complete her higher education. She wants to take my son with her. Since I can't look after my son alone, I also agreed with my wife. My problem is, when my son goes to Australia with his Mom, can I go to Australia for a short visit to see him under Immigration Law? I am a Graphic Designer and living in Sri Lanka.
