Coach tours are an option. Taxis are also available. But you will need a car to see the town and surroundings independently. This poses problems for the adventurous. Rental cars in the city often charge a premium for travelling further than 100-200 km, which is easy to do. After that, the rate is generally 25 cents a kilometre. Driving on unsealed roads is only allowed if you hire a four-wheel drive; even then, if you have an accident, you are liable for the entire insurance excess. So getting off the beaten track is difficult. At least one company only lets you drive to Menindee or Silverton.If you want a real experience you can always take a COBB & CO Coach ride that will take you back in time and off the beaten track, you can see some real country.
