1. What is Australia Post International Shipping?

Australia Post International Shipping provides reliable and cost-effective parcel delivery services from Australia to destinations worldwide. The cost is calculated based on the chargeable weight, which is the greater of the actual weight or dimensional (DIM) weight.

2. How Does the Calculator Work?

The calculator uses the Australia Post international shipping formula:

\[ Cost = \max(Actual\ Weight,\ DIM\ Weight) \times Rate \] \[ DIM\ Weight = \frac{Length \times Width \times Height}{5000}\ (cm) \]

Where:

\( Actual\ Weight \) — Physical weight of the package (kg)
\( DIM\ Weight \) — Dimensional weight calculated from package dimensions (kg)
\( Length,\ Width,\ Height \) — Package dimensions in centimeters
\( Rate \) — Shipping rate per kilogram (AUD/kg)
\( 5000 \) — DIM divisor for Australia Post international shipments

Explanation: The calculator determines which weight (actual or dimensional) is greater and uses that as the chargeable weight for cost calculation.

3. Understanding DIM Weight

Details: DIM weight reflects package density. Low-density packages (light but bulky) may incur higher costs due to taking up more space in transport vehicles. The DIM divisor of 5000 is standard for Australia Post international services.

4. Using the Calculator

Tips: Enter actual weight in kilograms, package dimensions in centimeters, and the applicable shipping rate in AUD per kilogram. All values must be positive numbers.
