Frequently Asked Questions (FAQs)

1. Are all Sim & Mack's products made in Australia?

Yes, Sim & Mack's garments are all proudly manufactured in Australia by our ECA compliant manufacturing partners based in both Adelaide and Melbourne.

2. Where does Sim & Mack source its fabric?

Fabric for Sim & Mack garments is sourced through our supplier and manufacturing partners based in Melbourne, Australia. We only use natural fibres for the body of our clothing, more than 95% of the garment, and in some garments employ a fraction of elastane/polyester in ribbing to ensure durability.

While access to certain fabrics, including that containing 100% certified Australian cotton, can be difficult for small businesses like ours to access due to high minimum order quantities, we have included this in our range where possible. We are also looking to add genuine organic cotton to our range but again, once we can reach the minimum order quantities to access commercial rates available to corporate fashion houses.

3. Who owns Sim & Mack?

Sim & Mack is a proud family owned business. Founder Andrew McKenna is a 5th generation Australian married to Simran, a 3rd generation Singaporean. We also have two little boys.

4. Do you ship internationally?

Yes, Sim & Mack now ships to the USA, Canada, Singapore & New Zealand. Please refer to our Shipping Policy for rates, terms and conditions. 

We are constantly reviewing other markets so please get in touch if you would like to see us service your country.

5. Which couriers do you use?

Sim & Mack uses Australia Post for all domestic and international deliveries. This ensures we are able to meet our customer's needs no matter where they live, including delivery to post-office boxes.

6. How do I know if my shipment has been sent?

Because we use Australia Post, customers will receive a tracking email to follow the progress of their shipment.

7. How do your sizing work?

At Sim & Mack, we try to keep things simple with all our garments being unisex in design. That means we use mens sizing from XS to XXL. Size charts are available on each product page so you can be sure you're selecting the right one for you.

8. How do you handle returns?

Sim & Mack has a 30-day return policy, which means all items must be returned within 30 days of receiving your purchase. We recognise that sometimes the size, style or fit just might not be right for you and we want you to be happy with every Sim & Mack investment. 

To be eligible for a return, your item must be in exactly the same condition that you received it, unworn or unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase. More details on the process to follow are available by viewing our Returns Policy.

9. Can I change my order?

If you need to change your order, please email and while we cannot guarantee you can in every circumstance, we will do our best to accomodate each request.

10. What if my order is faulty or incorrect?

In the unusual circumstance that your order is faulty or incorrect, please email and we will resolve the situation as quickly as possible.

11. What does Sim & Mack stand for?

This one is pretty simple, 'Sim' is the nickname for Simran Sidhu who is married to 'Mack', the nickname for Andrew McKenna. It helps that we shorten everything in Australia as otherwise our logo just wouldn't work! And together with our two boys, we're the family behind Sim & Mack.

12. Where is Sim & Mack based?

Sim & Mack is based in the western suburbs of the very liveable city of Adelaide, Australia.
