If you mean the red satchels with a tracking number then no they do not qualify for seller protection, they work just like the yellow express satchels. Even if they are lodged over the counter there is nothing from AP that has the buyers name and address on.

For protection you need to use registered post, click & send (lodged in at PO) platinum express, regular express parcel (not the satchels) or eparcel. The 5kg satchels used to qualify as you had a stamped slip with the name and address but I haven't bought one for years so have no idea if that is still the case.
