Goods purchased overseas, and delivered to Australia, do not normally incur any GST charges if the value is under $1,000, (at July 2011).
Orders over $1,000 will incur GST on the product value including delivery charges, and may also incur Import Duties.

There are many shops in the UK that will deliver to Australia, some of them even offering Free Delivery, others offer a low cost delivery, whilst some charge a very high price.
A few examples, at July 2011, are:
- www.bookdepository.com – Free Delivery Worldwide.
- www.amazon.co.uk - Free Delivery on book orders over £25.
Most companies will apply some special Terms & Conditions for international deliveries.
