ok so if Aus post accept the online payment as proof would they accept that if the parcel was lost and could I then make a claim through Aus post for items up to $50, or is there no such thing as claiming through the post office.

my items so far have not been worth a great deal most less than $10, just wondering if I could pop those in the red box so I can avoid the post office and just face the post office staff when I really need too, like when the parcel is too big or worth more than $50
