So I got this email from ebay

Important: “Netflix tax” effective 1 July 2017
From 1 July 2017, Goods and Services Tax (GST) will apply to fees on eBay.com.au, due to new legislation in Australia (the "Netflix Tax").

Businesses registered for GST will not be affected by this change if you register your Australian Business Number (ABN) with eBay here.

More information on this new legislation can be found here.

Regards,
The eBay Team
The more info link just brought me to the ebay.com.au homepage.

Any idea what's going on, looks like ebay changed their stratagy
