We flew out the next morning to Alice Springs, $200 AU. From there we drove to Ayers Rock. Watch out! If you have a couple of days, take a tour bus. If not, be prepared for expensive car rentals.
The car rental rates are reasonable at first, but it's the limited kilometers that get you. You get 100 KM a day but it's over a 1000-KM to drive to the rock! $380 later we got to the rock, by the way, the hype you'll hear about the Crater before getting to Ayers Rock? Is not worth the time at all, just a tourist "con". The desert, however, was beautiful! Sunset on the "Rock" is a must see!
The "rock" is a huge monolith; I've never seen anything like it! However, lodging surrounding the rock is very expensive! Make your reservations 6 months ahead (Desert Sands is the most inexpensive). We drove back the next day to Alice Springs. (It is good advice not to drive at night - camels, cows, kangaroos, etc. are out and running!)
