It is recommended to book flights between destinations in advance, as some locations are quite far apart. Domestic flights within Australia can cost around $100-200 per person, while renting a car for a road trip can range from $50-$200 per day.
If you have more time, consider adding a visit to the bustling city of Brisbane or hiking in the Blue Mountains near Sydney. For those with less time, consider combining the Uluru-Kata Tjuta National Park and Kakadu National Park into a packaged tour. Make sure to plan ahead for accommodation and tours as some locations can have limited availability.
