A couple lads from a lotus forum have imported elans to oz,
this is what they posted
shipping including tax's was about £1500, Compliance test £500
$1700 for the initial registration and about $600 a year after that.
i think,The process at the local registration office was fairly striaght forward. Fill out a form, provide proof of identity, proof of ownership, import compliance certificate and road worthy certificate. The guy then checked that the vin and engine number matched the documents and asked for a market value figure to which I told him $10,000 instead of the actual $30,000. My Great Uncle was a car sales man and told me to do this as the people at the registation office won't have any idea of the true value and they won't check. That brought the rego fee down by about $700. I then handed over about a grand and they handed me a set of number plates and a registration sticker for the windscreen. Took less than half an hour.
hope this helps
