The threshold for bringing goods into Australia is up to $1000 AUD, as such your purchase should not be charged duties if the value is below this amount.
However, if your order is above this value, customs fees will be requested from your local customs office while your order is going through the clearance process, just before the point of delivery.
If you have any questions, please don't hesitate to reach out and our dedicated customer care team will be happy to help!
