These financially savvy siblings decided to have a joint wedding to save money.
Andrea Walker (31) and her brother, Christopher Brennan (28), had back-to-back weddings and decided to have a joint reception with 100 guests at the upmarket Castle Hotel in Australia, Mirror reports.
The pair and their partners managed to save around £5 000 (around R92 000) each.
“I was chatting away to Christopher one day, moaning about the costs going up and then we just said, ‘Why don’t we do it together’?” Andrea said.
“Then it sort of snowballed from there. It happened by chance because it was convenient.
“It was also better for my dad who is suffering from emphysema to be able to see us both get married on the same day.
“It turned out we were all going for similar locations and colour schemes but the cost was spiraling,” Andrea said.
Andrea, tied the knot to Matt Walker (30), and then a few minutes later Christopher wed Adele (28), News Hub reports.
At some stage, before their joint-wedding planning, Christopher had begun to feel that he didn’t think he could afford getting married any time soon, The Sun reports.
“I first came up with the idea sitting on the sofa one evening when I worked out how cheap it would be to share the cost with another couple,” he said.
“We realised we could afford to get married after all if we shared the date with my sister.
"It was special day and it was plain sailing to be fair.”
The sibling's 61-year-old father, Colin Brennan, said that he couldn’t be happier that his children had a joint nuptials.
“It was definitely a very proud day and a good night as well.
"It's not really that surprising because they are so close to each other and really love each other. They decided to help each other out with the cost,” Colin said.
"It's really lovely that after sharing so much as kids, they'll now share wedding anniversaries too."
