Key facts about Sydney

How to get cheap flights from London to Sydney

Tips and advice from our flight experts

How long is the flight from London to Sydney?
The shortest flight time is around 21 hours and 55 minutes.

Can you fly direct from London to Sydney?
No, all flights from London to Sydney are indirect and will involve at least one stopover.

Which is the best London airport to fly to Sydney?

Generally, London Heathrow (LHR) is the most popular choice for flights to Sydney, although you can also fly from London Gatwick (LGW).

Which airlines have the cheapest flights to Sydney?
China Southern Airlines often have good deals on flights from London to Sydney, but it’s always worth shopping around.

When is the cheapest time to fly to Sydney?

If you're flexible on dates, try searching by month to see when the cheapest flights are. Summer runs from December to February, when visitor numbers peak, and March can often be the most expensive time to fly to Sydney – when the heat of summer is just starting to die down. On the other hand, you might find a cheaper deal on flights in May, when the low season starts and runs through to August.

How do I get into Sydney from Sydney Airport?
Trains run from the airport into Sydney Central station between 5am and midnight, seven days a week – the station is right under the airport terminal. Get an Opal card if you plan to use public transport while you’re in Sydney – it works a lot like an Oyster card in London. There are also plenty of buses, including the KST Airporter shuttle, which takes you to set points in the city, and hotel shuttle buses, which will be prearranged with your booking. You could also opt to take a taxi.

What are the top things to do in Sydney?
Ready to explore Sydney? Then you’re in for a treat. The capital of New South Wales and one of Australia's biggest cities is probably most well-known for the sail-shaped Sydney Opera House, which is a must-visit. But make sure you save plenty of time to climb the Sydney Harbour Bridge, potter around the Australian Museum, get lost in the Royal Botanic Gardens and of course – hit the sand on the unmissable Bondi Beach.

Do I need a visa to travel to Sydney?
Yes, you need a visa to travel to Australia. If you’re a British citizen you can get two types of electronic visitor visa. An eVisitor visa is available from the Department of Immigration & Border Protection, and there’s no visa application charge or service fee. Or, you can get an Electronic Travel Authority (ETA) from your travel agent or airline. Again, there’s no visa application charge, but there is a service fee.
