Former Hawthorn player development manager Jason Burt has added yet another explosive element to the ongoing crisis hanging over the Hawks and AFL.

On Wednesday Burt unleashed to social media to further air his grievance with the nine-month saga, claiming that a family behind the serious allegations made against himself, Alastiar Clarkson and Chris Fagan "are not Indigenous Australians".

All three men have consistently denied any wrongdoing.

His outburst came 24 hours after AFL boss Gillon McLachlan announced independent panel investigations looking into the allegations would be brought to a close, with an agreement met between the parties involved, and just days after Burt revealed his part, with Clarkson and Fagan, in the separation of "Zac" and "Kylie", one of the couples whose claims sparked the probe in September.

Speaking to The Age, Burt expressed his sympathies for any hurt caused to the families as the investigations played out, but was steadfast in claiming he had "nothing to say sorry for".

Individual accounts from four Indigenous former Hawks players came to light following their leak to the media last September.

Zac and Kylie have not participated in the investigation, but have been critical of the treatment afforded to them, via their legal representation, in recent weeks.

Per the agreement announced on Tuesday, the AFL confirmed there "no adverse findings" against the former Hawks coaches resulting from the probe, and that the league would not impose any sanctions against them, in addition to other elements.

The agreement does not prohibit the families from seeking court proceedings on the matter.

Lawyer Leon Zwier, who represents the six complainants involved in the investigation, confirmed on Wednesday afternoon that his clients would be taking this up.

"Our clients will be commencing an Australian Human Rights Commission complaint against Hawthorn Football Club, Clarkson, Fagan and Burt alleging breaches of the Racial Discrimination Act," Zwier told the ABC.

McLachlan also flagged an AFL investigation of Hawthorn to assess any breach of league rules during their premiership period.

On Wednesday, Burt claimed the agreement was made without his inclusion.

"Yesterday, the AFL announced an end to the Hawthorn investigation - an 'imperfect resolution'," he wrote to social media.

"I was not a party to the resolution but welcome the AFL and the independent panel's decision to clear myself and my co-accused.

"The Independent Panel had been provided with thousands of documents from Hawthorn for review. Moreover, I also provided the AFL with detailed information which I believed demonstrated our innocence, and is now supported by this finding, of the awful allegations that have been made by the complainants and leaked to the media without any opportunity to respond.

"Chris, Alastair and I were refused access to the Hawthorn documents until last week."

He stated that the four players behind the allegations required "substantial guidance, support and care" during their careers, and that the time each spent at Hawthorn "was maximised because of the on and off field support offered to each".

Burt went on to take aim at the club and incidents leading up to the saga, labelling the leak of the internal review a "disgrace".

"The Binmada "report" commissioned by Hawthorn and leaked to the media was a disgrace. Hawthorn's appointment of Phil Egan to conduct it was the first example of poor governance by Hawthorn Football Club in this process," he wrote.

"The so called "Welfare Check" on Indigenous players instead presented a selection of unproven and unreliable grievances and allegations which were not checked with me or many other Indigenous and non-Indigenous players at Hawthorn. The leaking of it to the media by whoever did it, was even worse.

"Yet within this process, it has been heartening to review the documents and interviews shared by all past players and officials (many Indigenous) who speak a different truth about how the Hawthorn Football Club operated in the same time as these vile allegations. The AFL could not speak this truth yesterday."

He added a bombshell claim that Zac and Kylie are not who they say they are.

"I also think it's important to clarify that "Zac" and "Kylie", who continue to make allegations to the media, are not Indigenous Australians," Burt said.

"If the outcome of this 'imperfect resolution' appeases the complainants, then I wish them well. Unfortunately, this outcome has done little to diminish the anguish and hurt experienced by my family throughout this ordeal and most likely well into the future.

"Few people would appreciate the path Alastair, Chris and I have walked for the past eight months under the weight of these grave and false allegations. I am glad that the allegations have finally been dismissed by the AFL and the independent panel and look forward to the opportunity to reveal the truth in any further proceedings."

According to reports, Burt declined to comment any further following his post.
