Hi ebay satchel has a signature requirement for travel by air.I have been told you can post perfume by road how do you do this through Aust Post ? cheers

If something is to go road only, like dangerous goods, or lithium batteries, put a sticker on the parcel saying "road only". You should talk to your local post office about this because they would be the best to advise you on how to go about it.
