Not a bad price if you are not after the more expensive OLED version.
Look at differences between 64GB and 512GB other than memory capacity, to decide yourself whether they are worth the extra $130 $104 over 64GB version.
If you do make use of the Kogan First free trial, remember to cancel it within 2 weeks ;-)
Cheaper to get the 64gb and upgrade it yourself. $142AUD for 1TB SSD
