    • Orders are dispatched Monday through Friday (except public holidays.) Unfortunately the postal system doesn't operate on the weekend.
    • If you order on a Friday afternoon, you can expect dispatch on the following Monday (assuming no public holidays get in the way!)

    Delivery Speed

    • Regular postal delivery speed depends on how far away you are from Sydney. NSW & WA orders typically arrive the next business day. More info about your destination is available on the¬†Australia Post¬†website.
    • For Express, deliveries are made¬†24-72 hours after dispatch.
    • Important: Regular post can take¬†up to 7 business days to reach the Northern Territories and rural postcodes in other states.¬†Choose express post for fast delivery.

    Shipping Methods

    • You can choose from Australia Post's standard service or choose Express for faster delivery.¬†Both options are tracked (within Australia) If you choose StarTrack Express, be sure to select a delivery address at which you will be available to sign for the delivery, otherwise it will be diverted to a post office.
    • For New Zealand, we use New Zealand Post¬†for delivery.¬†There are 2 flights per week.
    • If you live within Sydney Metro (10000-2249, 2555-2574, 270-2786, and 2890) then there's likely to be no advantage in choosing Express delivery.

    Adding an Item to your order

    • If you place a second order immediately after the original, then we will be able to combine them. However, our efficient dispatch system means that any delay between orders, means that a combination will not be possible and second delivery fee will be charged.
