Due to the Australia Post’s current algorithm, the postage for this product is determined by its dimensions, not physical weight. To fix this, The weight of this product has been changed in our system, allowing you to determine correct shipping costs.

The physical weight of this product is .034 kg, but the listed weight will be .074 kg to conform to AusPost conditions. Below you will find the exert from AusPost’s website, explaining how to determine postal weight.

The cubic weight is the parcel’s volume in cubic centimetres, divided by 6,000. To work this out, use the formula below:

Height x length x width ÷ 6,000 = cubic weight

For example: 50cm X 30cm X 40cm
= 60,000cm3 ÷ 6,000
= 10kg cubic weight

If the actual weight of your parcel is 9kg but the cubic weight is 10kg, we’ll charge you the cubic weight because it is greater. But if the parcel’s actual weight is 16kg, we’ll charge you the actual weight because it is greater than the cubic weight of 10kg.
