All packages we send are tracked. Please be sure to track your order on the Australia Post website for any helpful information about your package https://auspost.com.au/mypost/track/#/search.
Please allow the full time shown for delivery here before getting in touch. In our experience Australia Post will not open an investigation on a missing parcel until three business days have passed from the estimated due date. If your order has still not arrived we encourage you to get in touch with us and we can open an investigation with Australia Post on your behalf.
You are of course welcome to contact Australia Post at any time https://auspost.com.au/help-and-support.
