We offer free standard shipping to every province and territory in Australia. No minimum purchase is required, and all orders include tracking for your convenience.
You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).
If you need to return an item, simply login to your account, view the order using the "Complete Orders" link under the My Account menu and click the Return Item(s) button. We'll notify you via e-mail of your refund once we've received and processed the returned item.
Deliveries to Australia’s outer and remote regions may experience seasonal delays caused by severe weather or limited carrier availability. We appreciate your patience and recommend allowing additional time for your order to arrive safely.
Meet the Sierra Modern Home Smart Diffuser, a 400ml ultrasonic aroma diffuser that fits seamlessly into a modern smart home. It connects to your WiFi and works with Alexa and Google Home, letting you control aroma, LED color, mist intensity, and timers from your phone or by voice. The large tank supports up to 12 hours of continuous mist, making it ideal for extended use in living rooms, bedrooms, or home offices.

Orders are typically processed within 1 business day after payment is confirmed. Orders placed on weekends or public holidays will be processed on the next business day.
Our standard delivery time is approximately 2–5 business days after your order has been processed. Please note that delivery times are estimates and may be affected by factors such as weather conditions, carrier delays, or peak seasonal demand.
We currently ship orders across Australia. If we are unable to ship to your address for any reason, we will contact you to discuss available options or issue a refund where applicable.
Shipping costs are displayed at checkout before you complete your purchase. In some cases, free shipping may be available based on promotions or minimum order values shown on the website.

Please ensure that your shipping address is complete and accurate at checkout.

If a package is returned to us because of address issues, we may contact you to arrange reshipment. Additional shipping charges may apply.
Once a package is marked as delivered by the carrier, responsibility for the shipment passes to the customer. AustralianVit is not liable for packages that are lost or stolen after delivery. If you believe your package is missing, please check with household members, neighbours, or building management, and contact the carrier directly. You may also reach out to us for assistance.
While we make every effort to meet estimated delivery times, delays may occasionally occur due to circumstances beyond our control, such as severe weather, carrier disruptions, or peak holiday periods. We appreciate your understanding in such situations.
