Experience with dna recruitment agency

I’ve recently been applying for jobs through seek and one job in particular used a recruitment agency called dna recruiter, based out of Victoria, they contacted me today getting my interest in the job I applied for but didn’t exactly say it was mine, which leads me to my concerns, they emailed me a “onboarding form” to fill out and the things they ask for are really personal and raised some red flags for me like asking for my tax file number, a picture of my drivers license, Medicare card, it all seems like really personal information for a job they haven’t exactly gave me yet, mind you they did say they would have to check my references.

Am I being paranoid?
Are these normal things to ask for before actually being given the job?
The job is one I applied for and the agency seems legit it’s just I’m not too comfortable giving all that information out so early without a confirmation that the jobs actually mine

Anyone have experience with them or advice on how to proceed, I haven’t submitted it yet.
