One of our dreams is to travel the whole of Australia in a RV when the kids grew up. It will definitely a fun thing to do and the kids will enjoy their time living in a RV or commonly known as motorhome. A cousin did that a few years back and her kids had so much fun!
We have seen a few of those RV parks while we were in Perth and Melbourne and it does look kinda fun. My aunt told me that many senior citizens actually do that to past their time. There are amenities in these parks which made it convenient for campers. However, I am not sure if there are motorhome repair available but I think it will not be tough to look for one since it is another way of life there.
