I don't have an answer to your question - but I do know that the 2-1 selector on the car is completely electronic. The mechanical linkage has nothing to do with the driver's ability to manually shift the car into 1st. So my guess is that there is an electrical connection that's not hooked up.
I don't know if there's a site like
http://www.car-part.com for Australia... Probably wouldn't help much since your Q's are all typically JDM imports anyhow? What would it take to ship something to Australia? Maybe someone here could send it to you?
Good luck!
