My dream is to drive across Australia. Therefore, I flew to Australia, booked a car on the website and rented it. If you are wondering if you can drive through Australia? You can drive across Australia by following the Stewart Highway, which runs north to south for 2,834 km (1,761 miles). The road is completely closed, it can be driven by any type of car. You can drive from east to west on the Outback Highway, but this is a four-wheel drive only.
