The woman I married was from an overseas country with a poorer standard of living. We had arranged/agreed to have children over the years before she arrived in Australia, but when we married she did not want this. I feel she deceived me just to get into the country. We were married for 4 years and have no children. I was nearly 50 years of age at the time of my marriage. She now has a better standard of living here. She made no financial and non-financial contribution to the marriage. She now has her permanent residency and Australian citizenship. We are now divorced and she is seeking property settlement. Can I have the marriage considered void because it was obtained by fraud / deception, so that she would not be entitled to my assets? Thank you.
