Sportswear giants Nike are set to release the new Socceroos kits on Thursday 5 April, but Spanish website Todo Sobre Camisetas have released images supposedly of them today.
If accurate, the gold home jersey features unusual green lines detailing the sleeves in addition to a more standard green collar.
The away jersey would be a complete departure from the traditional navy blue, with Nike instead opting for dark green with a yellow diagonal stripe.
Todo Sobre Camisetas claims: "Although the photos are from a replica, we can confirm the design almost 100%."
The 'leaked' kits, still unconfirmed, have received a mixed response from fans on social media.
