Received the following email from Amazon US, stating they will soon redirect all customers in Australia to Amazon.com.au in order to be GST compliant. Good news is, it included a $20 off unique voucher, so I assume everyone with an account would get something similar.

As a result of changes to Australian GST law, on 1 July 2018 Amazon’s international shopping options for Australian customers will change.

While we regret any inconvenience this may cause, from 1 July we will be redirecting Australian customers from our international Amazon sites to amazon.com.au where you can shop for products sold by Amazon US on the new Amazon Global Store, available today. We have taken this step to to provide our customers with continued access to international selection and allow us to remain compliant with the law which requires us to collect and remit GST on products sold on Amazon sites that are shipped from overseas.

Amazon Global Store will allow Australian customers to shop on amazon.com.au for over four million items that were previously only accessible on amazon.com. This selection is in addition to the more than 60 million products that are already available on amazon.com.au across 23 categories, including books, fashion, toys, and electronics.

To welcome you to amazon.com.au, and thank you for choosing to shop with us, we are offering you a $20 voucher to redeem against your next purchase on amazon.com.au of items sold and shipped by Amazon AU. Just include your unique promotional code below at checkout when purchasing eligible items (see full terms and conditions below).
