From 1st July 2018, the Australian government has required that we add GST to all taxable sales to Australia.
If you have an ABN number for GST free shopping take a peek here to see how to apply this to your order.
Please note, if your order is over $1000 (AUD) and being shipped to Australia you will NOT pay the GST directly on moo.com but instead, you will have to pay the 10% GST rate at customs.
