Australia has become the latest country to probe Apple over its e-book price structure.
The Australian Competition and Consumer Commission (ACCC) is reportedly considering its options following the US Department of Justice’s lawsuit against Apple and five major book publishers.
In December, the European Commission said it was also looking into possible price fixing in the electronic books market.
"Competition concerns may arise where traders seek to restrict the discounting of products by way of restrictive arrangements with suppliers. Retailers with concerns should raise them with the ACCC," an ACCC spokesperson told the AFR.
This week, the US Department of Justice (DOJ) charged Apple and major book publishers with anti-competitive business practices in the e-book market.
It accused the companies of collusion which led to artificially inflated the price of e-books, forcing consumers to pay more for some of the markets' more popular titles.
In the DoJ suit, attorney general Eric Holder alleged that e-book sellers worked together to eliminate competition among stores selling e-books and ultimately increased electronic book prices for consumers.
Apple has yet to respond to a request for comment on the matter.
