I doubt it as the reason they require the conversion, in theory, is to make the vehicle safe to be used as a daily driver and if you then went and made a custom dash you would be modifying the vehicle in a way that was not tested and therefore could be unsafe. You would have to compliance the modified dash one would think. The law in all states is that if the vehicle is older than 30 years then it can be left LHD. The reason for the 30 year rules is that they figure a 30 year old car will not be used as a daily driver so therefore the LHD will have no real impact on day-to-day motoring. The exception to the 30 year rule is in NT and WA where it is 15 years old. In SA if the vehicle is not completely factory stock they require you to convert it to RHD even if it is over 30 years old.

All conversions have to be done in Australia, they will not permit a vehicle to be converted to RHD in the USA and then shipped. Already been down that road. Besides as R33_Dude said there are a lot of custom parts that they have no reason for having in the USA so you have to pay them to create all the mirrored parts like the dash so that wouldn't cut costs, it would probably add to them. Also in the cost calculations there has not been mention of Duty which is not payable on vehicles made prior to 1989 but is applied to all vehicles made after 1989. Another factor to add in, depending on the circumstances is Luxury Car Tax if you were buying a newer model and it pushed the price over A$55k. The good ol' Aussie Government sure do like getting a slice of the pie... a really big slice!
