How do I know what my tracking number is?
Once dispatched, you will receive a tracking number and you can view the status of your item on the Australia Post, StarTrack & Aramex Website.
Â
If your order has been processed and you have not yet received your tracking number, it's possible the email may have been sent to your 'Spam' or 'Junk' folder. If you still have not received it, please send us an email which includes your order number for us to investigate.
Â
I've received my tracking number but I cannot see any scanning on it?
It is possible that once an item is dispatched, there may not be scanning on it until Australia Post, StarTrack or Aramex scans it 'On For Delivery'. Unfortunately, we have no further information in regards to this. If you believe there may be an issue with the delivery, please let us know, or alternatively, you can contact Australia Post, StarTrack & Aramex directly.

Can I schedule a time for my order to be delivered?
This is not currently an option for deliveries from Australia Post.
If you are not home, a card will be left that allows you to collect your parcel from their nearest facility.
If possible, we recommend using a work address or an alternate address where someone will be present to sign for your order on your behalf.
At Umart, your convenience is paramount. Therefore, we offer a 30 Day Change of Mind Returns Policy.
Should you decide to return your purchase, please review the below information and contact our Support Team within 30 days of purchase. This will allow us to organise your product's return and refund of your product's purchase price (excluding initial delivery & handling charges).
Change of Mind Returns
Under Australian Consumer Law, businesses are not obligated to accept returns based purely on a change of mind. Nonetheless, at Umart, we strive to deliver top-tier customer service. We recognise that sometimes needs or circumstances change post-purchase. Hence, under specific conditions, we might be able to accept your item as a 'Change of Mind' return. Please understand that such returns are not guaranteed and are always subject to our approval. If you're uncertain or have queries regarding this, our Support Team is always here to assist.
Products for 'Change of Mind' returns must be in their original, FACTORY SEALED condition. We will no longer accept products that have been opened (including those with broken seals or removed shrinkwrap) for 'Change of Mind' returns. An exception to this would be if you were given incorrect advice or misled regarding a product's suitability by our staff or website.
Exclusions
Certain products, including those open box items, are not included in this policy.
Moreover, in our commitment to deter resellers and scalpers from speculative purchases, we hold the right to decline a 'Change of Mind' return for bulk orders consisting of more than three units.
Procedure for Returns
Please contact our Support Team to completing the Change of Mind Return Form. Products remain under warranty for faults or defects.
