Aust Post offer no "fragile goods" type service and state that as a guideline, your item should be able to withstand being dropped from about waist height, and able to tolerate up to 20kg parcels landing on it, because this is the weight of parcels they handle. As Devil's advocate, with this in mind, it is probably necessary to put some very stiff cardboard or such, in with items to mitigate against their being bent, if bending them is going to render them unsuitable for use.

Ebay's attitude is that as the seller, it is your resposibility to get the goods, in a suitable condition, to the buyer regardless of the carrier.

My advice would be to replace the goods for this buyer, and take steps to prevent it happening again, because Aust Post are never going to be able to say that bendable items won't get bent.

Hope this helps,

Marina.
