Football Coaches Australia president Phil Moss has described the fallout over the Alen Stajcic sacking as a watershed for the code.
Moss flanked Stajcic on Monday when the former Matildas coach spoke for the first time since his controversial dismissal from the role in mid-January.
While the FFA have given scant detail of Stajcic's axing, Moss said it was the governing body's responsibility to fully disclose the reasons.
"If you get pulled into an office and get told your job is no longer, the first question you ask is why, and to get some specifics around that," Moss said on Monday.
"We're not asking for anything that is out of the ordinary around anyone who loses their livelihood."
Moss, who revealed a number of Matildas coaches had also sought the FCA for support, backed Stajcic's call for an inquiry into his shock axing.
"This is a watershed moment in Australian professional coaching for our code because we're serious about being a legitimate stakeholder in the game," he said.
"Coaches have been, in a lot of ways, the most vulnerable stakeholder in the game in our history, with no protection.
"So we're here to to provide that protection and support."
Stajcic revealed on Monday he had ticked off on one of two surveys that formed part of the reasoning behind FFA's decision to sack him.
However it is understood the link to the Professional Footballers Association questionnaire was easily accessible to the public, raising questions about the integrity of the results.
"The fact that there was an unsecured element to the process certainly cast a lot of doubt about the flaws possibly within that process to begin with," Stajcic said.
"Like any organisation you always want to review your practices so that you can make them better and that's the reason that I gave the go ahead for the survey.
"Like any good leader you always want to find the parts within your team and within your culture; within your environment that you want to improve.
"I lost faith when I saw the actual report which, as I said in my statement in mid December, I questioned the processes of how those results got there."
Moss also said the FCA also questioned the validity of the survey.
"I can't go into the specifics but, yeah, fair to say there's a big big question mark hanging out of the validity of the survey," he said.
