The Socceroos will be wearing Nike kits throughout the next three World Cup campaigns after Football Federation Australia signed a new deal with the sports manufacturer, claiming it is the most lucrative apparel agreement for any Australian national sporting team.

Neither Nike nor the FFA would detail the dollar amount of the 11-year contract extension but FFA chief executive, Ben Buckley, said it represents an overwhelming vote of confidence in Australian football.

"The agreement goes way beyond the financial investment ... to have a partner like Nike it is not just about the dollars," he said.

"It's obviously a long-term deal but it's multi millions of dollars per annum and all that goes into supporting the growth of the game.

"It locks in substantial income on an annual basis for a long period of time and so then you can plan around that."

The deal includes kits and sponsorship of all national football teams, including the senior men's and women's teams as well as all youth teams.

"We've had a fantastic nine years together so far," Nike Pacific general manager, Paul Faulkner, said.

"We've had a lot of success with two World Cups and it made sense to give continuity to the game in Australia, continuity to our planning, continuity to the FFA's planning to make this the longest deal in Australian sports apparel history."

It is the third successive agreement between FFA and Nike, beginning in 2004 and now running through to 2023.
