As this was an increasing issue with our build as we've wanted to use products manufactured outside the US, I was very fortunate to have located our shock distributor here in the US. Spoke with the general manager of this company and there's no issues getting these shock for our build.
We're dealing with tighter restrictions and regulations when dealing with out of country products and how these product are delivered into the US. There's a new stricter imports list, but doesn't list AUS products. But the fact remains, it will be very tight to acquire products from countries that are on this new list as well as countries who aren't on this list.
Although we've not used any of these shipping companies, it is an alternative to locating an OBer that can purchase and ship these items to you. The issue could be (in their view) is they don't want to be held responsible lost or damaged items, thus not many would step forward and do this for you.
You have two options:
1) Locate a shipping company like
Pack & Send to ship those products to you or at least make contact with them just to find out if this is plausible and without restrictions. One would have to pay more for this serves depending on the product being sent.
2) Locate a comparable item or items via US retailers.
Otherwise, if an Australian OBer is not willing to ship this item to you the above choice would be the only other option.
