Western Sydney Wanderers' RBB and Sydney FC's The Cove have declared they will boycott this weekend's matches, in response to Football Federation Australia CEO David Gallop's comments yesterday.
The Yellow Fever joined the chorus of support, condemning the FFA for a perceived failure to defend A-League fans.
However the Phoenix fans said they won't be boycotting the match against Melbourne Victory, who staged a walkout during their match against Adelaide last weekend, which will be played in Auckland, not Wellington.
"We appreciate the stand other groups across the A-League are taking against the poor treatment of fans by the FFA and would like to publicly state they have our full backing" Yellow Fever founder David Cross said.
"Despite our strong support for this cause the Yellow Fever are not in a position to take any boycott action at the Phoenix's home game this weekend in Auckland."
The Yellow Fever also slammed Gallop and the FFA for the appeals process in place for banned fans.
"The FFA are acting as if they are above the law. There is no fair and transparent process in place in the league and a guilty till proven innocent mentality is damaging the already tense relationship with fans" Cross said.
"The FFA are playing it fast and loose with not only fans' rights but the truth regarding their own processes."
Gallop, while admitting it needed some 'fine tuning', affirmed the FFA's stance on the appeals process, placing the onus on banned fans to prove that they should have their bans overturned.
"The fundemental part of the appeals process is this, you have to show we made a mistake. You can't say I'm sorry, I made a mistake," Gallop said.
