On Tuesday evening, Zara Tindall and Jesinta Franklin teamed up for the Moët & Chandon Magic Millions Launch Party, which was held at the Surfers Paradise Foreshore Marquee.
Zara, 35, opted for an elegant navy Jayson Brunsdon gown which featured floral embellishments and capped sleeves.
The Queen's granddaughter, who is an ambassador for Magic Millions, finished off her look with black stilettos, drop earrings and a stylish low bun.
Zara's husband Mike Tindall, 38, kept things dapper in a navy blazer and khaki chinos.
Newly married Jesinta was a vision in a flowing white gown, which she teamed with gold statement earrings and black nail polish.
The model's stunning features were highlighted thanks to glowing, natural make-up and a slicked hairstyle.
In a beautiful touch, the 25-year-old brought along her parents Valerie and Andrew Campbell as her dates to the VIP soiree.
Jesinta and Zara were in good company with the likes of jockey Michelle Payne, 800 Words actress Melina Vidler and singer Taylor Handerson also in attendance.
Earlier in the week, Zara made her first official appearance since the tragic news of her miscarriage as she attended the annual Magic Millions Polo on the Gold Coast.
On Christmas Eve the couple, who first met in Australia in 2003 and are the proud parents to two-year-old daughter Mia, made the heartbreaking announcement they had lost their second baby.
It's believed the 35-year-old was about four months into her pregnancy.
"Very sadly, Zara and Mike Tindall have lost their baby. At this difficult time, we ask that everyone respects their privacy," a spokesperson for the couple, who share two-year-old daughter Mia, explained at the time.
