The Olyroo skipper's failure to attend the Townsville training camp did not go down well with Football Federation Australia with officials claiming they were unaware of the player's whereabouts.

Milligan was in England at the time players assembled and it is thought he was trialling with English Premier League giants Arsenal.

He was subsequently banned from participating in the forthcoming tournament in Malaysia but was far from happy with the decision.

His agent Tom Brookes said it was of deep concern to Milligan that his need to gain employment should be viewed so dimly and that he intended to appeal.

Ben Buckley, attending the launch of the first football Collective Bargaining Agreement told AAP: "The intention (on Milligan) is to have an outcome tomorrow.

"We need it to be sooner rather than later so the team can plan what they are going to do."

It is unclear what impact or what the next step would be should Milligan's appeal fail.
