  • Are there non-stop flights to Australia?

    Currently there is only one non-stop flight from the UK to Australia and that is operated by Qantas from London Heathrow (LHR) to Perth Airport (PER). All other carriers will have stopovers, which will depend on the home country of the carrier, so you may spend some time in Singapore, Hong Kong or Dubai, depending on which airline you are flying with.

  • How do I get to the Great Barrier Reef?

    You can book a flight from the UK into Cairns International Airport, which is the closest international airport to the Great Barrier Reef. You could stay in Cairns or book an onward domestic flight to Hamilton Island Airport (HTI), which serves as the main airport hub for the Whitsunday Islands.

  • Do I need a visa to visit Australia?

    It is necessary for British passport holders to obtain a visa to enter Australia as a visitor. You need to organise an electronic visa before you fly, and your passport only needs to be valid for the duration of your holiday in Australia.

  • I am visiting Byron Bay, what is the best airport to use?

    The closest international airport to Byron Bay is Brisbane Airport, which is a 2hr drive from the area. Another option would be to book a domestic flight to Ballina Byron Gateway Airport (BNK), which is a 25min drive from Byron Bay.

Top tips for finding a cheap flight out of the United Kingdom

  • Australia receives flights from the UK at many of its larger international airports, which also provide good onward connections to regional and domestic airports. For destinations in Western Australia, Perth Airport (PER) is the best airport to fly into. Brisbane Airport (BNE) and Sydney Airport (SYD) are on the east coast, while Melbourne Airport (MEL) and Adelaide Airport (ADL) are in the south east, so consider which one of these makes most sense depending on where your holiday will start. Cairns Airport (CNS) is in the north-east of the country and is a good option from the UK if you want to explore the very north of Queensland, while Darwin International Airport (DRW) services the Northern Territory.
  • If you are looking at flights to Australia so you can visit Kakadu National Park – a World Heritage site – think about flying into Darwin. This is the closest airport to Kakadu National Park and from here, you can complete your journey with a 3h road trip.
  • It is easy to exchange money in Australia. There are foreign currency counters in all the main airports, and it is also possible to use ATMs to withdraw Australian currency for your trip – please note that some of the more remote towns may not have ATMs available.
  • If you are travelling to the centre of Australia to see Ayers Rock and the surrounding area, consider flying into Sydney from the UK and booking a connecting flight to Alice Springs Airport (ASP). A direct flight takes around 3h and from there, you will need to hire a car for the 5-6h drive to Ayers Rock.
  • If you are travelling with children under the age of 7 and hiring a car to drive to and from the airport, it is mandatory to use an age-appropriate child car seat when driving in Australia. You should be able to reserve a car seat from the car hire company before you arrive. If travelling by taxi, be aware that, with the exception of New South Wales, it is not mandatory to use such a seat in a taxi, as long as the child can sit on the lap of an adult passenger in the back seat. In New South Wales, it is mandatory for children who are under a year old to be secured in some form of child car seat in a taxi, so you may want to consider bringing your seat from home.

a longer gap btw the supper and breakfast would have been better - felt like the sleep was way too fragmented on this red eye flight

I loved the full Taylor Swift selection but felt that the other selections were limited, didn’t span the popular music eras nor a wide enough range of music genres. BUT the seat and bed were GREAT (it was wide, long enough, had great storage, firm enough to uphold body postural comfort). Outstanding crew and really great food - gourmet innovative dim sum breakfast so different from the boring standard fare offered by many other business class products.

The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

It was very good experience on board to Sydney with SQ.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

Didn't like much at all Nowhere near enough legroom, narrow seats. Aisles not wide enough for safe food trolley access and husband had his knee hit cos not enough leg room. Would take a lot to convince us to fly Singapore Airlines again which is a pity cos it was always our go-to airline

Once again the meal served was delicious - we got chicken rice

Transfer within the same terminal and lots of facilities at the airport.

Very slow check in. Food poor and some of the special meals offered were not available. Luggage then didnt arrive and still waiting for news 48 hours later

We were taking the flight MU 8649 from Shanghai to Osaka and the original boarding gate was 20 and we didn’t receive any notification or broadcast about gate changes, and by the time we missed the original boarding time we check thr electric board and realized the gate was changed to 208 Also the flight was delayed by almost an hour and the crew member didn’t provide any explanation, after we finally boarded the aircraft was very hot, the crew member told me the air conditioning was not working and tried to calm passages down by offering iced water, all of us sat in the aircraft for another 40 mins before it finally took off

Seats not comfortable. We had requested vegan meal and it wasn’t given.

In my return flight they couldn’t identify my ticket or boarding pass, I had to go to 3 different counters until I was able to get my boarding pass. The food was on, it was the bear minimum. They didn’t even recognise that I was a Muslim and can’t eat meat, chicken or pork. In one of the trays I believe they served me pork. The staff were very pleasant, but they need to be aware of their surroundings more carefully, one of them stuck her lower belly right into my face! I was shocked and very uncomfortable.

China Southern was not the problem. I booked my flight through Kayak and also received a booking reference and alert details regarding departure time and gate numbers… however Kayak NEVER actually booked my flight! We were stranded at the airport without a flight for a long awaited holiday!

The flight was delayed hours and most flights from CS are always delayed. Plane was efficient and got us home but not the best food and no entertainment system at all.

No wheelchair service at all ( I did request that service and also purchased the priority assistant bundle) , what a waste of money

We bought an upgrade to Business Class at the airport but did not realise that it was not the regular Business Class. The 787 Dreamliner was very dated with the seats not as comfortable as other airlines and some things were almost coming off. We were then told that because it was an upgrade at the airport, we get to sit in the BC cabin but will be served economy class food. So when everyone else got served in china ware, we were given the tray you got in economy class. The wifi does not work. It only connects to watch movies (which is the same as what you find in the ICE) but the internet does not work. The cabin crew while were friendly, were not responsive. Overall, I will never fly China Southern again.

Flight canceled, but they didn't notify me. They arranged a nearby hotel and 4 meals for me to stay for 24 hours before I could board.

Wuhan - Dubai. Old plane: 1. Only USB charger. No power outlet to plug in.. 2. Super narrow seat layout 3. Toilet cover consistently fell down and hit my back when sitting on it.. :( 4. Entertainment system touch screen not sensitive, and need to press hard or use finger tips to hit. Crew were very nice and accommodating though.

The flight was okay it was the kayak customer service that was poor, I have been trying to change my name on my flight ticket 3 days before my flight and nothing got done about it even tho I messaged so many times and phoned, all I got in return was that is was being processed and still to this day nothing has been done about it, I think it’s disgusting and un needed stress to the trip.

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

The flight was delayed and one member of the crew was a bit rude. But apart from that all good.

Terrible experience resolving missed connection after flight was delayed. 3 hour queue at transit desk, not enough staff, no organisation, worst ever flying experience.

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

Crews are very rude and unhelpful. Cramped seats in economy. Foods are useless

Boarding delayed, no communication. I left the lounge, and heard a final call, boarding started after a 30 minutes.

Very tight seating. Crew seemed too dis interested and too slow to remove main meal trays.

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

1 hour delay meant missed my connecting flight and 1st day of holiday

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

Crew was amazing as usual. Very comfortable for a 13hour flight. Check in at ATL was terrible. Ticket counter charged me $200 for a small bag. Apparently Kayak sold me a zero luggage ticket. No carry on no checked. So the check in desk charged me a bullshit $200 dollar fee for a small gym bag weighing less than 20lbs. In true 3rd party ticket buying. This will turn into a finger pointing process between Kayak and Etihad. Now I'm going to have to ship my bag back in the mail a day ahead of my return flight.

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

The staff was kind and polite, but it was very very hot and no ways to have some fresh air.it would be also be nice to have more time to sleep, since it was a night flight

I WOULD ADVISE NOT TO BOOK YOUR FLIGHT ON KAYAK. THEY SHOW BETTER FARES AND AFTER I BOOKED MINE, I FIND OUT THAT IT DID NOT INCLUDE LUGGAGE. i HAD TO PAY $800 TO CHECK IN MY BAGS.

Very very bad service very tight seats never ever flying with Etihad again

I travelled from Adu Dhabi to Melb; service was minimal at best, when I asked for a bottle of water but no meal I was told it was not available- it seemed a cup would do. The staff were un helpful & dismissive. We had a family near us who I never saw obtain any assistance from crew- they were simply avoided! Meal was simple and adequate no hot drinks were on offer until close to arriving, with a pseudo breakfast. Seats were tight despite obtaining extra leg room. I will not be flying with Etihad again and will not recommend them to family & friends.

good flight. food is only so so. I actually did not eat the snack. it does not look too good on the passenger next to me.

Food no variations only beef of chicken no veggie meals

Better good than most, if not all European airlines. If you’re stuck in an economy seat anyways, China Eastern is a good choice because of shorter flight time, being able to overfly Russia

For the price we paid, I couldn’t complain. Was good value for money. Service was excellent but food was mediocre. Crew were excellent and spoke English. You will never go hungry. The food was ample but was mediocre. Entertainment limited and wifi doesn’t all allow you to access some social media. The best part was comfortable seats and bed (business class) with a screen to close out the rest of the cabin.

Great staff and food. Seats pretty uncomfortable but plenty of legroom. Entertainment system outdated.

The landings were smooth . Being unable to check-in online was terribly stressful and the queue at Haneda exemely long. We paid extra for window seats and did not get them.

Flight was fine, however we were not able to check in online, this adds to travel stress. Luckily check-in at Heathrow was quick, but we did not get the seats we paid extra for. We paid for a window and 2 aisle seats from Shanghai to Tokyo leg, but they changed us to middle seats. Not good :(

Again, I was presented with birthday pastries two times as a celebrated my birthday on both legs of my trip. I will keep flying to China using China Eastern airlines. As they made this trip a special one thank you.

It was my birthday while I was on the flight on China eastern airlines. They celebrated my day by giving me a personalized birthday card and also a very delicious pastry. I was surprised and thankful by the China Eastern crew! The whole staff was kind and professional? My second flight into China and the most memorable! Thank you-

I will never fly through China again. Maybe it was the mandatory retinal scan just to transfer to another flight or the complete set of fingerprints they require. There are many better and inexpensive flights to Asia if you look.
