New-fangled wedding vows by Oz couples walking down the aisle have a significant part of the traditional promise missing - "till death do us apart". Couples are now in favor of a more realistic "get out clause", just in case their love "shall falter or fail".
Celebrants have revealed that couples are replacing "lifelong commitment" clause with pledges "as long as our love lasts".
Some are even making agreements to review their marriage after five years.
Celebrant Coral Kortlepel said that many newlyweds had accepted "if you're not happy, you don't have to stay together."
"I actually had a couple recently that said: 'I will love you today, I will love you tomorrow and if our love shall falter or fail, I will respect you for the period of time that you were in my life'," the Daily Telegraph quoted Kortlepel as saying.
"People are starting to think that you're not meant to be with one person your whole life and perhaps they needed to learn a lesson from a marriage, but then move on, if they're not happy," she added.
Celebrant Michael Teulon said that he once presided over a couple who had made a "three-to-five year agreement, plus options", instead of committing for life.
But others said that they refused to oversee marriages not entered into "for life", arguing that those were invalid.
"The way the laws are, a marriage must be voluntarily entered into by a man and a woman for life, so I wouldn't actually perform a marriage, if the couple were putting a clause into their vows saying it might not be for life," celebrant Elaine Searle added.
