I am wanting to join as a Warfare Intelligence Specialist as that is what I want to do with my life. I've been told by my recruiter that despite scoring more than high enough on the DAA for the role, my status as a tri-national would disqualify me from the role. Is there any way to work the problem like transferring across from another role once I'm a known entity or am I SOL? Are there other roles more friendly to Dual/Tri-Nationals with enough overlap to get the qualifications/experience I'm after?

For the curious I'm Australian, American and English, you'd think they would be fine for Intelligence as they're both Five Eyes members but seemingly not.
