"We would like to inform you that beginning on July 1, 2018, Digi-Key Electronics will be handling shipments into Australia in a different manner due to amendments to A New Tax System (Goods and Services Tax) Act 1999 made by Treasury Laws Amendment (GST Low Value Goods) Act 2017.
The new law requires that Digi-Key collect Goods and Services Tax (GST) on any order with a customs value of $1,000 Australian dollars or less, except when Digi-Key has your valid Australian Business Number (ABN) on file, and we can validate that you are actively registered for GST on the Australian Government web site. The new rules apply to when an order is shipped, not placed, making scheduled orders and backorders shipping July 1st or later subject to GST as well."
Even better news if you have an ABN !! Are you watching Mouser? :-) Others?
