"You may now kiss your beautiful bride," said civil celebrant Janice Bradley.

And with those words, Lauren Price, 31, and Amy Laker, 29, turned to each other and embraced as one of Australia's first same-sex married couples.

On the same afternoon, two women wed in Melbourne in Victoria's first same-sex marriage.

Ms Price and Ms Laker solemnised their vows at 2pm at a wedding in Sydney's south-west on Saturday, while Melbourne couple Amy and Elise McDonald's ceremony took place at 4pm.
