'Contact sender' means your item has been returned to the sender.

This can happen if we couldn't process the item for the following reasons:

• Some of the details were wrong or were incomplete.
• We weren't able to deliver the item. We sent a collection notification, but no one picked it up in 10 business days.
• Some of the details the sender gave us when they posted the item were wrong or weren’t complete.

If this happens, we’ll let the sender know why the item has been returned to them.

You should contact the sender to organise redelivery.

For certain articles, Australia Post packaging may be cheaper. This is due to Australia Post packaging: 

• Being optimised to gain efficiencies in our parcel processing and deliveries network
• Having address label format and positioning, postage label and barcode positioning designed to minimise manual handling
• Using colours which are easily read by our scanners

We’re making sending simpler and more straightforward by introducing national flat rate postage for items 5kg or less sent within Australia.

Now if you’re sending from Melbourne to Sydney, or Cairns to Karratha, you’ll pay the same flat rate postage, depending on the speed of delivery chosen.

When you use your own packaging, flat rate postage is based on the weight tier your item fits into: up to 500g, 500g to 1kg, 1kg to 3kg and 3kg to 5kg.
