Covercraft, Seven Hills in Sydney.
Michael Penn (owner) is a member and will design a cover to fit your car with all the right fabrics. It is not cheap but nor is the quality that you will get.
Otherwise Supercheap and all the other car shops have them for around $40 unless they are on special and it might save you a few dollars there.
The discussion has been had before so go search the forum and you will get more ideas.
