"In the US, you do not get our Domestic, all European, most Japanese Trucks that we get here."
Simple: Don't want them in the USA anyway and wouldn't sell even if they were offered. We have all the trucks and their capabilities we want, need, and will sell already right here in the USA now. People here nearly all are much smarter than to need to pay double+ for something they don't need or want. Your vehicle market on your "island" is about 14th of the volume sold in the USA and it's because there's 14 times as many people living in the USA alone and then add Canada and the rest of North America. Australia's total population is about equivalent to just the tail on a dog screaming for total dog control bragging rights! Like just 1 brick in a wall!!!
