Vehicle shipping to Australia

I am going on an extended holiday to Australia. Since I will be flying from the United States, all I will have with me on the plane is essentially the clothes on my back, plus what I can take in baggage. However, since I will be there for sometime, I would love to have my own car with me. So what I need to know is about vehicle shipping to Australia. Yes, I realize it is a long way to ship a car. But I love my car and I would really enjoy having it with me since I will be in Australia for 6 months. So, what I need to know is the best way to ship my vehicle to Australia. I also need to have an idea as to what it will cost for me to do this. Of course, if you can also send me information on any Australian laws that I must follow once I have my vehicle there, I would greatly appreciate it. Thank you for emailing me with the information.
