In reply to apneaquatic:
> but I always get a notification that they cannot ship Arc'Teryx clothing outside of the US
Restrictions such as this are often due to distribution agreements; a distributor in one country agrees not to sell to other countries where they would interfere with "someone else's pitch".
Using Arc's 'Find a Store' facility to find stores reveals two in Australia:
Sea To Summit Pty Ltd
6-8 Brown St East Perth
Perth, Western Australia
Australia
6004
+61.8.9221.6617
Pretty sure S2S are a manufacturer/distributor.
hmmm...

"Arc'teryx: coming soon"
Skiman-Inflatacraft
176 Burwood Road
Hawthorn, Victoria
Australia
3207
+61.39.818.1622
But I guess you're hoping for US prices...
