Tony Abbott's daughter, Frances Abbott, has taken to social media to announce she will be campaigning for same-sex marriage ahead of Australia's postal survey on the issue.
Ms Abbott, one of three daughters of former Prime Minister and avowed 'No' campaigner Tony Abbott and his wife Margie, used her Instagram page to make the announcement on Friday when she appeared in a white t-shirt with the words 'vote yes' written on the front.
"I don't really care much for politics," Ms Abbott wrote.
"But I do really care a lot for love. All love is good. Let's celebrate it."
The post was then followed with the hashtags #voteyes #yesyesyes #postalvote #getaroundit #marriageequality.
Her position is at odds with her famous father, who just two days ago penned a column in The Sydney Morning Herald stating same-sex marriage would fundamentally change society.
Mr Abbott used the column to decry proponents of same-sex marriage as being responsible for bullying and hate speech.
Last month, the former Prime Minister took to the airwaves to explain his position.
“The concept of marriage is between a man and a woman, preferably for life open to children, that long predates our constitution, it long predates our parliament, it long predates the civil law, frankly,” he told Sydney radio station 2GB.
“It is something that evolved many centuries ago to protect women and children in a world where they were much less secure than they are now. That’s why I would be very reluctant to change.”
Mr Abbott’s sister Christine Forster, a Sydney councilor and marriage equality advocate who is in a same-sex relationship, said his comments were hurtful but the pair had agreed to disagree.
“The Abbott family is like every other family. We do have differences of opinion on some things but we are a normal, functional family,” Ms Forster said.
