I would seriously consider sourcing from US (wheelbuilder), just compare the price per spoke difference. Starts to add up.
Both Sapim CX-ray and DT aerolites are crazy expensive in AUS, but much cheaper in US.
Built some wheels at end of 2014 with CX-rays from wheelbuilder, best price I could get, delivered no problems, plus all the other parts and tools I needed. Would use them again.
If you just want one or two spares for a repair, given postage from the US, then maybe buy local.
Great spokes, they just cut through trail debris. Strong and light.
Found the bladed spokes are also easier to build with once tensioning, if you use the DT swiss bladed spoke holder tool, no wind up like round spokes, no pinging on first ride either.
