If you want to rely on public transport, Sydney’s vast network makes this easy.
You will need an Opal card for Sydney’s ferries, buses, trains and light rail—or further afield to Central Coast, the Illawarra, or Blue Mountains. This means you will load Australian money onto your card to pay-as-you-go through the gate when entering and then tap again when exiting.

Apply for a NSW Opal card.

Uber. is quite an effective way to get around, with less cost than a taxi. Just download the app, set up a profile with credit card, and choose the type of booking you need dependant on your budget and concerns. It is easy.

Ferries. Sydney is separated by a huge body of water, so Sydney Ferries provide an enjoyable way to get about. Take a train to Circular Quay and set off for the Parramatta River, Manly, Double Bay, Mosman, Taronga Zoo, Balmain, Cockatoo Island or Darling Harbour. Ferry services operate daily, until midnight.

Rent a car. There are several hire car companies (Avis, Budget, Europcar, Sixt, etc) if you want to pick a car up at the airport or city and go to your accommodation and get familiar with the city roads. From $55 per day plus insurance.
