As Australia’s richest woman, Gina Rinehart can just about do – or be – anything she likes. And on Tuesday in Brisbane, the billionaire made her runway debut as a fashion designer, of sorts.

According to the magnate herself, Rinehart “had a personal involvement” in designing the new collections for Driza-Bone and Rossi, the iconic Australian brands she bought through her S Kidman & Co company in late 2023.

Under Rinehart’s watch, the oil-skin coats – made famous by The Man From Snowy River, and awkwardly posing world leaders at economic forums – were given a lighter, softer makeover for the brand’s relaunch at the Brisbane Fashion Festival.

Sadly, the tycoon was not present for her star turn, but in a statement, Rinehart says she wants the brands to evolve into “a staple not only for those on the land but also introducing lighter-weight material for travel wear, and new colourful and comfortable boot ranges for special events and evening wear”.

Australian audiences already got a sneak peek of the boots during the Olympics – Rinehart’s other cause célèbre – when medallists including Ariane Titmus and Emma McKeon sported gold Rossis to a victory party on a boat on the Seine. Rinehart, 70, has been a major financial supporter of Australian swimmers for more than a decade.

On Tuesday, that support translated into several Paris medallists, including Shayna Jack, Elijah Winnington and Jack Cartwright, modelling in the show, held in King George Square. Of course, Brisbane will host the games in 2032.

As the sporting heroes turned models gingerly strutted down the runway wearing coats in shades of sandy orange, buttercup and more traditional khaki to the theme song from The Man From Snowy River, they were met with rapturous cheers from family members in the front row.

The coats also included linings that paid tribute to Australian pioneers, and two prints from Cairns-based Kaantju and Quandamooka designer Brianna Enoch, who’d already worked on a commission – a painted pair of sneakers – for Rinehart previously.
