Humans have been delivering packages for many years and in gaining so much experience, we’ve pretty much perfected our technique. Although things can go wrong and packages are occasionally lost or get stuck in the system, this is rare. Good courier services have the systems in place to ensure that items are sorted quickly and accurately before being efficiently delivered all around the world. It all comes down to well-trained staff and efficient processes. This system is too complicated to explain here and it varies from company to company.
No matter where you live in the world, it’s possible to find a fast courier service. However, it’s also true that some countries have better systems than others. In more developed countries, where internet use is more widespread, it’s easier to compare couriers and track packages. That’s why even massive countries like Australia have quick delivery services.
