FAQ

Why put a box inside a prepaid satchel?

A box protects fragile or crushable items in transit, while the satchel lets you keep its flat-rate postage price.

How do I know a box will fit?

Each box on this page is grouped by the satchel size it's designed for. Always check your packed box against Australia Post's current satchel size and weight limits before sending.

Are the dimensions internal?

Yes — box dimensions in our product titles are internal unless the title says “External”.
