Football Federation Australia and Nike have agreed a 11-year sponsorship deal.
The agreement, which will take the partnership to 20 years, is believed to be the biggest deal the FFA has entered since its 2004 inception.
"Nike is dedicated to the development and success of the game of football both locally and on a global scale," said general manager for Nike Pacific, Paul Faulkner.
"This renewal solidifies Nike's commitment to the sport in Australia and supports each and every player in the game.
"From the elite level with the Qantas Socceroos and Westfield Matildas, to professional via the Hyundai A-League, to our various grassroots initiatives such as youth teams, The Chance and Manchester United Premier Cup, Nike is focused on ensuring the ongoing success of Australian Football."
FFA CEO Ben Buckley added: "Today's announcement represents an overwhelming vote of confidence in Australian football and it's incredibly exciting future.
"It's a powerful symbol of the emerging strength of the game in this country. I thank Nike for their unwavering commitment to Australian football and their substantial investment in the game."
