Western United will be the name of the A-League's 11th club, and it will play in the unorthodox colours of green and black.
A two-week fan survey helped club chiefs to decide on the key elements of the club's identity, unveiled on Wednesday.
Western United won out over Western Athletic, Western Melbourne Warriors and the catchy Westside Pride.
Football boss Steve Horvat said the decisions meant "this week the club proper has been born."
"It will no longer be a consortium or a bid. We don't have to refer to a group any more, we can refer to ourselves as a club," he told News Corp.
The bid was chosen as the A-League's next side last December ahead of a team based out of Dandenong.
That franchise, which still hopes to be admitted to the competition in further expansion waves, will now need to search for new colours after using black and green in its promotional material.
Western United has yet to secure a stadium deal for next season but has two players on its books ahead of its October debut.
This week, Socceroos right-back Josh Risdon decided to trade Western Sydney for the west of Melbourne.
Risdon, 26, said he was "absolutely stoked" to become the first Australian to join the ambitious side after they announced Greek international Panagiotis Kone as an inaugural marquee.
"With the signing of Panagiotis as the marquee, I can see the club has big ambitions both on the park and off it," he said.
