You do not need to be a resident to be married in Australia.
Many visitors to Australia marry during a holiday visit. Celebrants from The Celebrants Network are trained to work with overseas couples and can incorporate traditions from your home country into the ceremony if you wish.
Overseas visitors must meet the same Basic Conditions and legal requirements for marriage as Australian residents including giving one month's Notice.
Marriage in Australia does not give you any right to stay in Australia
It is important to understand that marrying in Australia, even if you marry an Australian citizen, does not entitle you to remain in Australia. The Department of Immigration and Border Protection website has information about visas for partners.
