eSIM Travel Tips for Sydney

Sydney is the gateway for most international visitors to Australia

The Airport Link train connects Sydney Airport's international and domestic terminals to the CBD in around 13 minutes. All underground City Circle stations including Central, Town Hall, Wynyard, and Circular Quay have 4G. Download your transport card (Opal) and the Transport NSW app before your flight for fast airport-to-city transit.
Download offline maps for Blue Mountains day trips
