International delivery times are estimated by DHL Australia and vary region to region. 7-15 days are the average delivery times but we urge customers to check their tracking code with DHL to find out exact location details of your package.

We package and ship Australian orders on all business days, excluding public holidays. International orders are processed once a week and therefore have a longer handling time of up to 7 days.

Where is my item?

If you have any problems while tracking your package, your first point of call should be to DHL or your local postal service in your region. The contact number for DHL in your region will appear on the DHL tracking page with your tracking number.

Once an item has entered your country with DHL, it will move into your local postal service of the country. You can use your tracking code with them for up-to-date information and tracking.

We can also help find your package from DHL, but this can take 2-3 business days for our DHL support requests to be reviewed and answered.
