NRI-Australia (Questioning behalf of a friend)

My friend is an Australian Citizen - Indian born and His wife is PR in Australia (sponsored by him). They are Married in India under Hindu marriage and it's been 8 years of married life with a kid. due to lots of conflicts between them and family issues. Now he wants to get divorced in Australia and his wife is not agreeing to take a divorce or not in contact with him and took the child with her to India. it's been over 10 months since she's been staying at her parent's place. My friend and family tried to patch it up and it did not work. Now, he had enough of these situations and conflicts and he does not want to go through an Indian divorce system as it will take years to resolve all the stuff. He decided to take a divorce in Australia. is it possible without her wife being present in Australia? is the divorce granted valid in India? will there be any issues escalating? if she files police cases against him or his parents in India? Please advise all Pro's & Con's Thanks.
