You shouldn't need to get a new fuel rail. The adapter kit from Deatschwerks just allows you to put 95+ injectors (which I think are the style you're wanting) in a 91-94 fuel rail. I initially asked them if I could just swap in a 95+ fuel rail and avoid the adapter kit but they said it wasn't a bolt on deal.
They're a really good company to deal with. I originally sent my stock injectors in for service, but 2 of them were bad and I ended up just getting all "new" 95+ phase 2 injectors which are supposed to be less prone to randomly dying.
I'd bet you could have them ship parts to you, but I'm not sure what shipping prices are like from the US to Australia. Check out their website here:
