Jesinta Franklin considered adding "marriage celebrant" to her CV so she could officiate at her friends' same-sex wedding this summer.
But the David Jones ambassador and vocal supporter of marriage equality said that given the wedding is in Thailand, she didn't end up needing a legal qualification to conduct the wedding of the US-born couple.
"We were hoping same-sex marriage would have been [legal in Australia] by then ... but hopefully on November 7 we will at least know the outcome of the [postal] vote," Franklin said at the Caulfield Cup preview day in Melbourne on Friday.
"I didn't have to do [the course] and that was the most heartbreaking thing. When they asked me if I wanted to do it, I said I would love to ... but when they told me ... it's not official on the day, it actually made me quite teary."
Still, Franklin, 26, said if she "does a good job" and her friends can eventually marry legally in Australia that she would consider obtaining the qualification.
"If I get asked again, maybe I will do the course - it could be my retirement plan," she said.
In Australia, all marriage celebrants must complete a Certificate IV in celebrancy, which usually takes between nine and 12 months.
Franklin and her husband, Sydney Swans star Lance "Buddy" Franklin, included a reference to their support for same-sex marriage in their wedding ceremony last year.
For their first anniversary on November 5, Franklin is planning a special surprise during the couple's upcoming beach holiday.
Franklin said the pair hadn't yet had much time to reflect on their "massive year" both personally and professionally, including Buddy winning the Coleman medal for the most goals kicked in the AFL season.
Whilst I was in the air many of my close friends marched the streets of Sydney for Marriage Equality. I wish I was there to stand proudly side by side with you all ?????? I believe all Australians should be treated equally under the law, in every facet of society. Marriage equality might not be something that crosses your mind or something that will impact your life directly, but for many Australians this impacts their lives daily. Later on this year I get the honour of officiating two of my best friends marriage at their wedding. I didn't have to do a celebrants course or take part in any official paperwork because, heartbreakingly, I can't marry them officially as their marriage is not recognised in Australia. This truly breaks my heart because when I look at them I witness two of the most amazing, kind, caring human beings who love eachother endlessly. They both work hard, contribute to our society, pay taxes and all of the other things Aussies do, but they aren't allowed to get married!? Marriage should be a right, not a privilege! So when you receive the postal vote for Marriage Equality don't just think; I'll do that later, or, what does it even matter? This is your chance to make a difference and do something that will positively change the lives of so many Australian's. ??????????????????????

"One of the things that attracted me to Bud is he's so humble," Franklin said. "He got All-Australian, he polled really well in the Brownlow ... for a man who's 30 ... he's done really well. I'll make sure he celebrates while we're away."
The Franklins will be trackside at next Saturday's Caulfield Cup as guests of David Jones. Other stars set to attend include Karl Stefanovic and his girlfriend, shoe designer Jasmine Yarbrough, and actresses Rachael Taylor and Pia Miller.
"It's not as intense [as other race days] ... it's just fun and we have a bit of a dance," she said.
