One thing that may be in your favor is the quality standards for diesel fuel in Australia.
If you did not know previously, governments around the planet set different lubricity standards for diesel. Europe and Canada standards are set at a micron wear level of 460, while US standards are at 520. In other words, the fuel in the US is actually a poorer grade of fuel when compared to Europe/Canada.
So take some time and find out where your fuel standards are in Australia. Considering that previous to ultra low sulfur diesel fuel most high sulfur diesel was at a micron wear rating in the low 400 range, today's US standard (at least) results in a very dry, lower lubricity fuel. Shoot, its 25% drier than it used to be. And from what I have read, most diesel components wear better in fuel standards in the 460 range.
Just to conclude, you may have a distinct advantage already just in fuel standards from those who post here to answer your question. And this advantage may improve performance compared to owners of the same vehicle in the US.
:S Sure took me a lot of words to say I don't know what Australian standards are.
