Thanks for posting here! All our products listed on amazon.com only come with US plugs. We do not have any products that come with Australian plugs.
As amazon’s global shipping options enables this product to be shipped to destinations all over the world, we do mention ‘…premium 20W UL certified power adapter (US AC Wall Outlet Plug, 100-240V 50/60Hz)…’ under ‘In the Box’ section of Product Description on our amazon listing for this product at http://www.amazon.com/dp/B00ECDM78E/ to avoid confusions.
As the power adapter itself is capable of supporting inputs in the range of 100V to 240V 50/60 Hz, our global customers just get a US to local plug adapter to connect our products with US plugs to the local power outlets.
Customer satisfaction is top priority for us. We never ever want customers stuck with products that are not happy with. So if you do not want to use a plug adapter to connect the US plugs on the power adapter to the local power outlet, I recommend you return the unit to amazon for a refund via http://www.amazon.com/gp/css/returns/…
