That being said, they also have a nice selection of public transport to choose from. First, you have taxicabs very easy and convenient and quick, as long as you're not traveling in rush hour traffic. However, I find them also very expensive in addition to the cost of traveling. There are also different rates for different times. There's also a rate for booking a taxi as well as a right for waiting. So while I was here, I really didn't take many taxis at all. And easier and probably more affordable option to taxis would be Uber. As far as I know, Uber runs really well in Sydney and its quite convenient and easy to get from anywhere in the city. Other than taxis and Uber. There are also trains, light rails, ferries and busses. All of those use a contactless card called the Opal card, which is a pay as you go card. You can get this card at the airport at 7-Eleven, Woolworths and a bunch of retailers and kiosks, as well as some train stations. Sydney trains are, for the most part, very reliable and very affordable. But due to the size of this city, your most likely might still have to take a bus or walk a bit from the station to your destination.
