On 21 August 2015, the Australian Treasurer announced in a press statement the country would expand the goods & services tax (henceforth: GST) of 10% also to good imports worth less than 1'000 AUD.
Furthermore, back in May 2015, the government revealed it would expand the GST to imported intangible digital products.
Both amendments are planned to come into force on 1 July 2017.
 
Update
On 10 February 2016, the Treasurer has provided more information on the GST for imported intangible digital products (cf. Sources). He mentioned that the tax would bring in an estimated 350 million AUD of revenues and specified that the underlying law would "require overseas vendors selling digital products or other services, such as 'apps' and downloads of digital content, to register, report and remit GST on their sales to Australian consumers".
