Simply put, an interstate courier delivers packages from one state to another. This mode of delivery is very common among businesses that have to ship products outside their state to other states within the same country. And even for non-business owners, this mode is also very common. It could be that you are studying at a university in one state and your home address is in another state, and you need to have some documents from home shipped to your school. In this case, the documents will be sent via interstate courier.
Interstate courier is for packages that have to be transported from one state to another—all within the same country. If you’re planning to send a package to another country, that will require you to use an international courier.
In Australia, interstate couriers are mainly divided into two types: (1) economy and (2) express. If you’re confused as to the difference between the two, or you’re not sure which one you should go for, you can check interstate courier rates on this website.
