Flying from Australia to the UK: Flights, Entry Requirements, and What to Expect

Quick answer: what Australians need to know about flying to the UK

Flying from Australia to the UK takes around 22 to 28 hours in total, with no direct, non-stop route from any Australian city as of 2026. Every option includes at least one stop, typically in Dubai, Singapore, or Doha, with Emirates, Singapore Airlines, and Qatar Airways covering most routes. Australian passport holders need a valid UK Electronic Travel Authorisation (ETA) before boarding, on top of a passport that covers the length of their stay.

Quick facts:

• Average flight time: 22 to 28 hours (including stopovers)
• Airlines: Emirates, Singapore Airlines, Qatar Airways
• Entry requirements: A valid passport and a UK Electronic Travel Authorisation (ETA)

Flying from Australia to the UK means signing up for a long day of travel, with at least one stopover, whatever route you choose. When you’re going to be spending 20+ hours travelling, a little extra planning goes a long way to ensure you have a smooth journey.

We’ll give you an overview of the airlines and routes on offer, how long you should expect to be travelling, what the UK’s Electronic Travel Authorisation involves, and what to expect once you land at Heathrow. We’ve also covered the money side of the trip, since currency and transfers are something our team at Remitly helps Australians with every day.

Which airlines fly from Australia to the UK?

Three airlines cover most of the flights between Australia and the UK: Emirates, Singapore Airlines, and Qatar Airways. Emirates flies from Sydney, Melbourne, Brisbane, and Perth, with a layover in Dubai that typically runs two to four hours, and its A380 service is a drawcard for travellers who want extra cabin space. Singapore Airlines connects from the same cities via Singapore, with layovers of three to five hours at Changi Airport, which offers plenty of fun ways to pass the time. Qatar Airways routes through Doha, generally from Sydney, Melbourne, and Perth, with a free stopover programme at its Hamad International hub if you’d like to break up the trip. Qantas doesn’t fly non-stop to the UK — it codeshares with these partners instead, so a Qantas booking may still route you through Dubai or Singapore. Flights Perth Airport via Qatar and Emirates include a shorter first leg to the Gulf than flights from the east coast, which trims a few hours off the total journey.

How long does the flight from Australia to the UK take?

The full trip from Australia to the UK usually takes between 22 and 28 hours, including your layover.

• Sydney to London via Dubai: around 23 to 25 hours total
• Melbourne to London via Singapore: around 23 to 26 hours total
• Perth to London via Dubai: around 20 to 22 hours total, the shortest of the main routes

Finding the best fares: what Australians should know

Economy return fares from Australia to the UK vary by season and airline, and tend to run lowest in January and February, outside school holidays in both countries. Booking three to six months ahead generally gives you the best shot at a reasonable price, while fares climb sharply over the northern summer and Christmas. Fare alerts on Google Flights or Skyscanner are a straightforward way to track your route before you commit. Flying out of Perth can work out cheaper as well as shorter, since the first leg to Dubai or Doha is a shorter sector than from the east coast, which is often reflected in the fare. In September 2026, round trips in January cost between $1500 and $2000 for flights from Melbourne, Sydney and Perth.

Do Australians need a visa to enter the UK?

Australian citizens can visit the UK for tourism or business for six months or less without a visa, but you do need a UK Electronic Travel Authorisation (ETA) before you travel. Introduced in 2025, the ETA costs £20 (around AUD38). Processing is often complete within 24 hours but can take up to 3 business days, and it’s a good idea to leave extra room before you fly in case further checks are needed. Once you have an ETA, it’s valid for multiple trips over two years (or sooner, if your passport expires).

To apply:

1. Download the ETA App or use the online form. (Note: the UK Home Office strongly prefers travellers use the app, and it’s usually the fastest way.)
2. Complete the form with your passport details and answer the eligibility questions.
3. Pay the £20 fee by card.
4. Wait for confirmation — it’s linked electronically to your passport, so there’s nothing to print or carry separately.

What to know about Australian customs before you leave

Before you fly out, it’s worth knowing that Australia’s biosecurity rules will apply when you come home. Certain foods, plant material, and animal products need to be declared on return, and the Australian Border Force website has the current list. On the UK side, most personal food items are fine, but meat and dairy from outside the EU face restrictions. Consider checking the UK’s customs guidance beforehand.

At the airport: departing Australia

Australia’s main departure points for UK flights are Sydney (SYD), Melbourne (MEL), Brisbane (BNE), and Perth (PER), each well set up for international departures. Arriving around three hours before a long-haul flight gives you a comfortable buffer for check-in, bag drop, and security.

If you hold an Australian ePassport, SmartGate can speed up passport control considerably, though check your airline’s own check-in cut-off separately, since that’s a different queue. Some airports use a separate international terminal from domestic, so allow time for an inter-terminal bus transfer if your connecting flight or drop-off point lands you elsewhere. The Sydney Airport terminal guide is a useful check if you haven’t flown out of there recently.

Managing your body on a long-haul flight

Long-haul flights carry a small, increased risk of deep vein thrombosis (DVT), particularly on a journey this length, and both the NHS and the Australian Department of Health recommend some simple precautions:

1. Wear compression socks, especially if you have any existing circulation risk factors.
2. Get up and walk the aisle every couple of hours.
3. Do simple ankle and calf exercises in your seat between walks.
4. Stay hydrated — cabin air typically sits at just 10–20% humidity, far drier than normal, which adds up over a 20-hour-plus journey.

For the jet lag itself, the westward direction to the UK responds well to a simple strategy: stay awake through your first leg to your layover city, then aim to sleep through as much of the second leg as you can.

What to pack in your carry-on for Australia to UK flights

A two-leg journey this long is more comfortable with the right carry-on. Worth including: noise-cancelling headphones or earplugs, a travel pillow, and an eye mask for sleeping on the second leg, plus compression socks to go with the circulation tips above. Carry an empty water bottle that you can refill after security, and pack lip balm and moisturiser, since cabin air dries out your skin more than you’d expect over 20-plus hours. A light layer is always a good addition, since cabins can run cold, along with a change of clothes in case your luggage gets lost or you spill something.

Australian international airports apply the standard 100ml limit on liquids, gels, and aerosols in carry-on baggage, so pack toiletries accordingly or plan to pick up travel-sized versions after security.

Arriving at Heathrow: what to expect

Most flights from Australia land at Heathrow’s Terminal 3 or Terminal 4, depending on your airline. Check the latest information for your flight from your airline, as well as our Heathrow Airport guide, for terminal-specific details. As of 2024, Australian ePassport holders can use the UK’s e-gates at border control, which usually means a faster path through immigration than the manual queue.

If your bag doesn’t turn up on the carousel, report it at the airline’s baggage desk before you leave the baggage hall. You’ll need to file a Property Irregularity Report (PIR) there and then, since it’s much harder to claim for a delayed or damaged bag once you’ve left the airport.

Getting from Heathrow into central London

The Heathrow Express also offers a £10 Advance Discounted Single, which must be booked at least 30 days in advance.

Fares and times are based on Heathrow’s and TfL’s published guidance and can shift, so it’s worth checking current prices before you travel. Australian contactless debit and credit cards work directly on the Tube, buses, and Elizabeth line through TfL’s contactless system, though your card provider may charge a foreign transaction fee on each tap.

Money and currency: what Australians need to know

The UK uses the pound sterling (GBP), and the exchange rate against the Australian dollar shifts regularly. You can check the live rate on the Reserve Bank of Australia close to your travel date rather than relying on a figure that might be weeks old.

The UK is largely card-first, with contactless accepted almost everywhere, so you don’t need much cash. Most Australians use one of three approaches: their regular bank card (usually the highest foreign transaction fees), a travel money card (typically cheaper for everyday spending and ATM withdrawals), or a small amount of cash exchanged beforehand as a backup.

If you’re sending money to the UK while you’re there, or transferring funds home, Remitly makes it easy with guaranteed delivery times and tracking every step of the way.

Frequently asked questions

How long is the flight from Australia to the UK?

The full trip takes around 22 to 28 hours, including your layover, since there’s no non-stop service from Australia. Sydney and Melbourne routes typically run slightly longer than Perth, which offers the shortest first leg to hubs like Dubai or Doha.

Do Australians need a visa for the UK?

Australians don’t need a visa for tourism or business trips of six months or less, but you do need a UK Electronic Travel Authorisation (ETA) before you fly. It costs £20 through the official gov.uk service and is usually approved within a few days.

Which airlines fly from Australia to the UK?

Emirates, Singapore Airlines, and Qatar Airways cover most routes, connecting through Dubai, Singapore, and Doha respectively. Qantas doesn’t operate non-stop UK flights, but it codeshares with these carriers, so a Qantas booking may still route you through one of the same hubs.

When’s the cheapest time to fly to the UK from Australia?

January and February tend to offer the lowest fares, since they fall outside school holidays in Australia and the UK. Booking three to six months ahead generally helps too, and setting fare alerts on Google Flights or Skyscanner makes it easier to catch a good price.

Can I use my Australian debit card in the UK?

Yes — the UK is largely card-first, and contactless is accepted almost everywhere, including on the Tube and buses through TfL. Your Australian bank may charge a foreign transaction fee on each purchase, so a travel money card like Wise or Revolut can work out cheaper for everyday spending.

What’s the best way to get from Heathrow into central London?

The Heathrow Express is fastest, at around 15 minutes, but pricier, from about £25. The Elizabeth line and Piccadilly line take longer but cost less, and a black cab or rideshare is the most expensive option, generally £60 or more depending on traffic.

Can I drive in the UK on my Australian licence?

Yes, a full Australian driving licence is generally valid for visits, though carrying an International Driving Permit alongside it can help since it includes a translation. If you’re staying longer term, the UK’s DVLA sets out separate rules for exchanging or converting a licence.

Conclusion

Flying from Australia to the UK comes down to three practical steps: apply for your UK ETA well before departure, confirm your route and layover city, and sort your travel money before you go rather than at the airport. Getting the financial side right, from exchange rates to how you’ll send money to the UK while you’re there, makes the rest of the trip easier to enjoy, whether you’re visiting for a few weeks or considering what’s involved in becoming eligible for UK citizenship down the track.
