It's hard to say what they actually have on him.
I don't think you can put someone in jail for simply being a fraud.
They can deport him for all the times he lied on Aus immigration applications and for being convicted overseas.
But they can only charge him for his Australian crimes.
The penalty for a fake driver's license is often just a $1000 fine or so.
The penalty for fake passports can be a couple of years to ten years max of jail time.
He took money from GGB but hard to prove, as she gave it to him willingly.
With JO, they'll need to prove he stole title deeds and jewellery, but there's a possibility for 'kidnapped with intent to financially benefit from'.
Similar with Marion, unless they find her remains and can prove he's connected with them.
Edit: Maybe some kind of money laundering due to the transfer of money and security envelopes.
I think there are much better legal experts here who can give much more accurate and better insight.
Would love to hear what the realistic charges could be
