Party 1 and Party 2 have replaced Bridegroom and Bride on the new marriage forms to be used by all Australians from Saturday as the country prepares for the first same-sex weddings next month.
The forms which give the government a month's notice of a couple's intended marriage also provide tick boxes for male, female and "x" gender - which is described as "indeterminate, intersex or unspecified".
The attorney-general's department form, which went online on Friday, replaces the Bridegroom and Bride category with Party 1 and Party 2.
Under that, boxes must then be ticked in a "Description of party" section, giving the options "groom", "bride" or "partner".
It's anticipated same-sex couples will submit the forms in droves as soon as they become valid on Saturday, with the first weddings expected one month later on January 9.
