Australia post tracking

[Khyber]

Hi all,
Just wanted some guidance..
A dealer from Australia has sent me a medal a couple of weeks ago by registered post to India. The tracking number does not show up on Australia Post tracking. - it says cannot be tracked.

I just noticed from the receipt the seller sent me that it says 'documents only' He has apparently sent it in an envelope like ordinary mail. Will it be a problem and will the medal be impounded? I had told him to send it by registered post and also give a description in the customs declaration, but he has apparently just sent it as a letter.

It is still not showing up in the tracker either in Australia or India so am a little concerned..If it has a number it ought to show up somewhere..can any one here tell me what is likely to happen in this case?
