Football Federation Australia has given the green light for the FFA Cup to begin next year, with commercial arrangements the only condition yet to be finalised.
The knock-out style competition is being modelled on England's FA Cup, with various state amateur and semi-professional teams as well as A-League sides to take part.
FFA announced the final will be staged in December 2014, with A-League clubs expected to enter around September/October.
FFA CEO David Gallop insists the tournament is a key component of the A-League's growth.
"The idea of the FFA Cup has captured the imagination of the football community and there’s a huge groundswell of support," said Gallop. "Everyone in the game is keen for this concept to come to life, but the prudent way forward is to ensure the right commercial and organisational foundations are in place.
"FFA Management now has a mandate to conclude the many positive talks we've had with broadcasters, sponsors and commercial partners."
