The longest serving Matilda was bid an emotional farewell on Monday night, at the team's friendly pre-Olympics match on home ground.
Lydia Williams began her career as a Matilda at 17, almost two decades ago, debuting in July of 2005 in a friendly match against the Korea Republic in Jeonju.
She played her final game at home on Monday night, claiming victory 2-0 over China at the Accor Stadium in Sydney.
A celebration of Williams' career
Before the game, her teammates, staff, friends and family gave the Noongar woman a guard of honour while her biography was read to the over 75,000 people in attendance.
Trailblazer and tennis legend Evonne Goolagong-Cawley presented Williams a Booka, a kangaroo skin cloak traditionally worn by Noongar people.
The Wiradjuri woman draped the Booka over Williams, which was decorated with the story of Williams and her family.
"To receive that gift from Evonne was just incredible and I think that was probably the moment that tipped me over emotionally," Williams told the crowd.
"I don't know if it's like, game recognises game. It was a lovely moment.
"A lot of sporting women in Australia just want to leave the game better than when they first arrived in it and don't really realise the impact of how they have shaped the culture of not only women's sport, but just Australian sport."
Williams said that receiving the Booka from such "an icon" and a "legend of tennis" was "absolutely, really humbling".
She recognised the significance of the moment for the younger her.
That was kind of a cap off to the kid that grew up in the desert that fell in love with football.
Her teammates unveiled their uniform, which read "Thank You Lyds" - a homage to what the athlete gave to the sport.
Williams took to the field wearing the captain's armband.
Final moments on the field
Just before half-time, Williams ended her game with coach, Tony Gustavsson, bringing on goalkeeper Mackenzie Arnold.
Williams left the field to a roaring standing ovation.
Williams' contributions to the sport were praised by teammate Clare Hunt.
"It was just an awesome celebration of all that she's achieved personally in her career but also for Australian women's football and women's football across the world," Hunt said.
"It's always a privilege to share the field with Lyds.
"She's very old-haired and very mature and very experienced, so it's amazing to be able to be in an environment where you learn from her every single day."
Williams will hang up the goalkeeping gloves in late July after the Paris Games.
