A few weeks ago, I was in the same situation when I was traveling from a hotel on the outskirts to the center of Alice Springs. Local taxis can charge high fares, especially for short distances, and even more so when there are a lot of tourists. I was worried, so I tried pre-booking with GetTransfer. There are different types of cars, and you can immediately see the final price for a
taxi Alice Springs. It ended up being cheaper for me because there were no surprises when paying, and the driver arrived on time. If you're planning a trip to Hermannsburg, I highly recommend booking in advance — it's less stressful, and you won't have to hail a cab on the side of the road.
