Dear client,  

I'm sorry to hear that you and your children are in this situation. No, your husband cannot legally prevent you from leaving India with your children if you are all Australian citizens. As Australian citizens, you have the right to enter and leave Australia freely.

If your husband is refusing to return your passports, you may want to contact the nearest Australian embassy or consulate in India for assistance. They may be able to provide you with temporary travel documents so that you can return to Australia with your children.

It is important to note that family law and custody arrangements can vary between countries, so you may want to consult with a family law attorney in Australia for guidance on your specific situation once you return.

In the meantime, it may be helpful to try to communicate with your husband and see if there is a way to resolve the situation peacefully. If you feel threatened or unsafe, you can also contact local authorities or the Australian embassy for assistance.
