I want to send a vintage item that may be considered prohibited (on the signature part of a satchel) by road from NSW to VIC instead of by air.  I know there used to be by road stickers you could useand not sign a satchel

now googling I can't find much info. 

do I post without signature........but then there is the risk it will be sent back to me, or is there a by road option nowadays?  anyone in the know?  thanks
