Tips and advice from our flight experts

Looking to save money on flights from London to Sydney? Then it’s time to shop around. The London to Sydney route is a popular one, which means you’ve got lots of options to choose from.

Flights from London to Sydney land at Kingsford Smith Airport (SYD), and there’s an average of 5,558 flights every week. All flights on this route are indirect, so you’ll have at least one stop on your journey to Australia. Your layover might be in Hong Kong International Airport, or it could be somewhere like Dubai or Beijing.

Generally, London Heathrow (LHR) is the most popular choice for flights to Sydney, although you can also fly from London Gatwick (LGW). The most popular airlines are Singapore Airlines, Virgin Atlantic and British Airways. If you want a bargain, keep an eye out for flights with China Southern Airlines, as they often have good deals. Or, you could broaden your search by looking at flights to other airports in Australia to see if there are any cheaper options.

When you fly is just as important as who you fly with. 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 will cost anything from $13 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 – this can cost anything from about $30 to Sydney Central Station, but tolls may be added along the way.

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 of A$20.
