IngramSpark vs Amazon KDP: Which Is Right for Australian Authors?
This is the most common platform question Australian self-published authors ask — and the answer is not one or the other. The two platforms were built for entirely different purposes, serve different distribution channels and work best when used together. Here is what each one actually does and what the recommended strategy looks like for Australian authors in 2026.
The Core Difference
Amazon KDP
A retailer-first platform. It exists to supply Amazon's marketplace and is exceptionally good at that job. Independent bookshops view Amazon as a direct competitor and will rarely, if ever, order a book supplied through Amazon's distribution network.
IngramSpark
The self-publishing arm of Ingram Content Group, the largest book wholesale distributor in the world. It uses the same distribution pipeline as Penguin, HarperCollins and Macmillan, reaching over 40,000 retailers, libraries, schools and online stores globally.

Booktopia and Australian Bookshop Access
For Australian authors wanting their books listed on Booktopia and stocked in independent Australian bookshops, IngramSpark is effectively required. It distributes print books to Booktopia, Readings, The Nile, Fishpond and Kogan through Ingram's global network.
Being available through Ingram means the book can be ordered by a retailer. It does not guarantee proactive stocking. That requires a direct approach to individual bookshops — but it makes the book commercially viable for any retailer who chooses to carry it.
The Recommended Strategy
Multiple expert sources and practising Australian self-publishers converge on using both platforms:
Direct Amazon access. Consider KDP Select for Kindle Unlimited if targeting that readership.
Use your own Thorpe-Bowker ISBN for maximum distribution and bookstore access.
For wide ebook distribution beyond Amazon, if you are not enrolled in KDP Select.
Critical sequencing note: obtain your own ISBN first, publish to KDP first, then publish to IngramSpark using the same ISBN. Doing this out of order creates complications that are time-consuming to resolve.
Royalties and Tax for Australian Authors
KDP royalties are paid in AUD for Australian authors with currency conversion already applied. IngramSpark pays in USD through Payoneer. Australian authors earning royalties from US platforms should be aware of the Australia-US tax treaty, which typically results in 5% withholding rather than the default 30%. Authors must complete IRS Form W-8BEN within their account settings to claim these treaty benefits. Authors who have not completed this form may be having excess tax withheld from their royalties.
