Special Marriage Act, 1954 issue

Briefly, what is the process to get our marriage registered in India under the Special Marriages Act? I am an Indian citizen (Hindu) getting married to an American citizen (Agnostic) in India on the 9th of June, and we both normally live in Australia. As I understand it, one of the requirements under the Special Marriages Act is that at least one of the people getting married is resident in the district the marriage is registered in. Noting that I will be travelling to India for a few days over Easter break (16/17 April), both of us will only return to India to get married on 28 May. We have tickets to return to Australia on 22 June. Additionally, I will be living in Gurgaon while the wedding ceremonies will take place in Agra. Is there any way we can register the marriage in India despite the fact that neither of us will be resident for 30 days?
