I too am in Australia, not even got my stryker yet, but risers were always gonna be on list.Yes you can use the stock cables, you just have to re-route them a bit. I can ship anywhere but the shipping is additional. I have looked into shipping to Australia in the past and it is a possibility but it is very expensive and so far it has not been worth it to anyone. The last shipping quote I got was for Sydney and it was around $120 just for the shipping. Send me a message with your address and I can get the shipping estimate for you.
