    Flights from London (LHR) to Sydney (SYD)

    Flight route information

    Cathay Pacific offers daily flights from London (LHR) to Sydney (SYD). Flights take approximately 22 hours and include a layover in Hong Kong International Airport (HKG).

    Upon your arrival in Sydney

    After arriving in Terminal 1 of Sydney Airport, you’ll find a variety of means to get into the city. We recommend taking the Airport Link Train Service, which will bring you to downtown Sydney in approximately 15 minutes. If you prefer to take a taxi, they are easily accessible at each Terminal and take around 20 minutes to get to the heart of the city. There are also buses and car rental services available.

    A brief introduction to Sydney

    Sydney is Australia’s largest city and offers travellers a unique combination of world-class natural beauty mixed with a vibrant downtown. We recommend starting your trip by visiting some of the city’s landmarks such as the Sydney Harbour Bridge and the iconic Sydney Opera House. Those interested in history and culture will appreciate Sydney’s many world-class museums and galleries, such as the Australia National Museum and the Art Gallery of New South Wales. Foodies will delight in Sydney’s endless dining options - be sure to visit the lantern-slung restaurants around Kensington Street, as well as the international flavours found at Darling Harbour and Barangaroo.

    Bondi Beach is popular with locals and tourists alike, and is renowned for its pristine sands and curling blue waves. Be sure to have a swim in the Bondi Icebergs Pool - a historical landmark by the ocean that features a larger lap pool, a smaller kid pool, as well as a café.
