As I previously stated importing a Samsung SmartThings hub from the US is a terrible idea (Discussion) however with the Samsung SmartThings hub now in Australia (with legal Z-Wave frequencies for NZ) it now seems like a great idea to import and that is just what I did:
This was a pretty straight forward process:
1) Sign up an account with https://www.ausff.com.au/ (use the coupon HI5 for them to waive the $5 opening charge).
2) Activate your account - you do need to send through your license (blank out the DOB and license number) as well as a bill. This was quite annoying, but as they state on their site there are things you can blank out for privacy reasons so I wasn't worried about that. Pay with PayPal else you need to also send through your credit card photo (which is against the T&C's of most credit cards) and use a unique password as they store their passwords in paintext (ugh).
Once activation is completed simply order your SmartThings hub from RACV (Link) and ship it to the freight forwarder. Note, there are also many sensors included and being a SmartThings WiFi hub depending on what your current WiFi solution is, it could be worth grabbing a few for them to mesh and extend WiFi over your house. Shipping in my experience took 3 days.
Ausff will email you once a package is in their possession - it cost $56.57NZD for me to send the package to NZ (pretty expensive) but it did arrive here in 3 days also. Just select the cheapest DHL option, they sent my package via Australian Post priority post.
Total cost to import: $390.94
