Get your luggage, exit Sydney, NSW Airport (SYD-Kingsford Smith Intl.), and pick up your rental car. Which one you hop into depends on where you want to go. If you’ll be mainly driving in downtown Sydney, around 6 miles from the terminal, choose something small and zippy. A compact car with nimble handling will suit those bustling city streets. But with almost endless things to see, like the striking bays of the region, you’ll probably be racking up those miles. A bigger vehicle, like an SUV or a full-size car, will make longer road trips a joy.
