Probably not, they follow GCC Specs here, which seem very similar to USA specs. It also probably wouldn't be worth the cost or hassle, you will get a decent price for the car in Sydney, it would be worth almost nothing here.
There has been a 1995 E220 listed here for QR 19000, which is about AU$8000. I doubt that they got their asking price.
If you are worried about learning to drive on the other side of the car, don't sweat it, most people are comfortable after a couple of hours driving.
