Until the child is born he cannot do anything to you. You have your own passport and you can book a flight and leave. I would suggest you leave before the child is born and come home.
He can only stop you leaving after the child is born.
The agreement you have is not binding as it is not a court order. It is your body and you can leave now and he as a father has no rights until the child is born.
Once the child is born in Sydney if he wishes to have a bond he can come to sydney.
Only once the children is born can he commence and action in Australia to get custody or to have some contact.
If you are in Hong Kong then the laws of Hong Kong will apply. But while you are still pregnant you can do what you want and he cannot stop you.
