Samsung Gear VR 2017 (S8 compatible) available on Amazon for USD 89.92 + USD 12.71 shipping to Melbourne = USD 102.63 total (~AUD133.13).
According to camelcamelcamel the USD price seems to have been around USD89 since June 23rd but the weakness in the USD over the past week (AUDUSD=0.771 at time of posting) means this is the cheapest it's been on Amazon in AUD terms.
Note: Only the US version ships to Australia but as far as I can tell there is no difference between the US and International versions.
For comparison:
2016 version on Good Guys ebay with 15% off is $103.90 shipped but not compatible with S8
2017 version from Kogan is $159 shipped
they have what im assuming is the older model at officeworks on clearance for 68 dollars

not sure if the older model has the wireless controller
seems lower res and doesnt fit some of the newer phones?
