DO NOT use Sendle as your courier, they may be cheaper but so is their service and their insurance claims policy is non existent. They damaged my item during transit and I was asked to provide evidence of the item prior to sending and after it was delivered as well as how it was packaged. The buyer provided me with the after delivery photos and I provided them with photos before delivery. I sent them everything they asked for including how it was bubble wrapped and double boxed and they said it's not enough evidence for my claim to be accepted. So even though I sent them all my proof they still didn't cover my claim for the damaged item, so I am out of pocket for the item and postage. I find that Sendle aren't prepared to honor their policy for insurance claims as they state, so just a heads up you could be out of pocket.
In most cases it is deemed inadequate packaging, same with AP, where an item must be able to withstand having a 20kg weight dropped on it from waist hieght, presume sendle requirement is similar.
In your opinion it was packaged correctly, check the guidelines, as others have said the same applies with Australia Post. Try making a claim with Australia Post, I can guarantee you a hard time.
