Summons and annulment

I am an Indian citizen and a resident of Australia, married to an Indian citizen for 2 years. Due to differences in outlook towards life we decided to mutually part our ways and take divorce. I requested to apply for a mutual divorce in Australia after 1 year separation due in March 2020 which would then be accepted by Indian law as well. But all of a sudden I have received a court summons by email towards annulment and hearing on 7th March 2020. I never received any summons copy by post or in person delivery. The summons doesnt say what the charges are nor says under what section it has been filed. I cannot trace any details of it online on ecourts website using case number nor the officials in family court are sharing any details. The summons attachment does not have any court address nor case number. Case number is mentioned in the subject of email. My wife too is mum on this and keeps pressing me to come down to india without any reason. It seems to be a trap. I have work committments making it difficult to fly to India. Please guide me as to summons are fake or genuine? If they are genuine what should be my next course of action? Thanks.
