Australia's uniform for Paris Olympic Games opening ceremony unveiled with extra pressure on this year's editions, which will be showcased in the global fashion hub of Paris.

The new outfits were modelled by rising athletics sensation Torrie Lewis, Matildas striker Michelle Heyman, water polo star Tilly Kearns, Tokyo volleyball silver medallist Mariafe Artacho del Solar, champion gymnast Georgia Godwin, canoe sprinter Tom Green, rugby sevens captain Nick Malouf, men's water polo co-captain Blake Edwards, and Australia's first Olympian in breaking, Jeff Dunne.

The green blazers, double-breasted for women and single for men, will feature the Australian Olympians' oath on the inside jacket pocket.

Australia's female Olympians can wear a T-shirt or tank top, featuring green and gold ribbing, under their blazers, and can choose between a chino short or a green and gold ombre pleated skirt.

The men will rock the shorts and a tee.

Olympic boxer Paul Fleming's Indigenous artwork Walking Together, and Ngalmun Danalaig (Our Way of Life) from Torres Strait Island artist David Bosun are featured.

The Australian Olympians' Oath:

"For the honour of representing Australia.

"With acknowledgment and respect for the ancient Aboriginal and Torres Strait Islander histories and their ongoing connection to the continent, water and seas.

"For the pursuit of excellence in every endeavour, with gratitude to those who make it possible.

"For the Spirit of sport. For my fellow Olympians whom I respect and support. Since Edwin and forever.

"Once an Olympian, always an Olympian.

"I have had the honour of receiving four Australian Olympic Team ceremony uniforms and I treasure each one. For Olympians, it brings us together, from different sports, backgrounds and experiences, proudly uniting us through that team uniform," said chef de mission Anna Meares — the cyclist's name emblazoned alongside 300 other Summer Olympic gold medallists through the jacket's lining.

"It creates a connection and sense of belonging to the Australian Olympic Team's proud history. It begins our Olympic experience and post-Games continues to be worn by Olympians proudly to events, long past our days as elite athletes. It's a uniform that is treasured and the quality, comfort and feel brings a pride and confidence to us all.

"I love that the Olympians' Oath will sit on the inside lining at heart level, with the support of all Australia's Olympic champions throughout history wrapping around each of our team members for Paris."

Football veteran Michelle Heyman is back and bidding for a spot at her second Olympic Games, eight years after her first.

"The Australian Olympic Team is so special. I love wearing my Rio Olympic jacket, when I talk to schools or do events, I'm so proud to wear it and show that I'm an Australian Olympian," she said.

"Not a lot of people get to wear these jackets. Every time I put it on it makes me feel like I'm part of that special team who have achieved something remarkable."

Heyman was a member of the Matildas team that lost a heartbreaking quarterfinal shootout to host Brazil at Rio 2016 before retiring from international football in 2019, meaning she missed the team's fourth-placed finish in Tokyo.

But Sam Kerr's absence with a torn ACL has put Heyman, who will be 36 when the Games start, on a path to another Olympic berth.

"To wear this uniform in Paris with my girls would be a dream come true," Heyman said.
