Joybuy has the Mi pad 4 LTE listed for $194USD + GST and the Mi pad 4 plus listed for $249USD + GST.
In order to get the best price you need to sign up with a new email to get the $5USD/7AUD coupon, and pay with paypal (they are doing a $5USD off $40+ spend promotion right now for the first 10,000 orders) to get a further $10USD/$14AUD discount on the total price. (Math works out a bit differently when it gets down to decimals as the first $5 coupon is applied before GST and the paypal discount after)
These prices are comparable/better than the Chinese RRP for these devices.
The LTE bands are fully compatible with Vodafone but misses B28 for Optus and Telstra.
-you can't use these for calls
-it is wildvine level 3 right now so no HD streaming via Netflix
-the 8 inch model has no fingerprint sensor but the 10 inch model does.
-8 inch model is around 20cm by 12cm (a bit thinner than A5 paper size and same height) and the 10 inch is around 25 by 15.
-both versions have same resolution (1920 by 1200) so the PPI for the 8 inch is actually higher (but unless you really peep you can't tell)
