There is no warranty on eBay unless you buy from an authorised seller/re-seller who is registered in Australia

eBay do not provide nor enforce a warranty even when one really does exist

Pointless sending a photo to eBay

The eBay MBG is not a warranty, nor did the OP ask about a warranty

But I 100% agree, if a buyer wants a real warranty, not just a word on the screen, then yes, absolutely buy from seller that can actually provide one
