Prices are indicative, shown in AUD and refreshed from provider APIs where available. Always confirm the final price on the provider's site - it is the price that applies. We may earn a commission if you buy through our links, which never changes what you pay. A row labelled "Featured partner" holds a paid position at the top of the table. Partners are listed before providers who pay us nothing, as our terms set out; sorting by price ignores all of that and orders on the number alone. How we make money.

When Australians fly to United Kingdom
July is the busiest month for Australian trips to United Kingdom and March the quietest, across 588,550 trips a year. The peak is when fares and accommodation cost most and when the cheaper insurance and eSIM options sell out first, so a trip that can move a few weeks either side of it is a trip that costs less.

If you are not flying out of Sydney
The international leg is rarely the problem. The domestic flight that gets you to it is: Canberra to Sydney is cancelled 5.3% of the time against a national average of 1.9%. Book both legs on one ticket and a missed connection is the airline's to fix. On separate tickets it is yours, and the international fare is the expensive half.
Route and connection data for United Kingdom

Your passport
United Kingdom wants the length of your stay of validity covering your whole stay. A fare is non-refundable long before a passport renewal is.
Entry requirements
No visa, but Australians need an approved UK Electronic Travel Authorisation (ETA) before boarding.
Travel insurance only covers a cancellation that was not already public when you bought the policy, so the cover is worth buying with the fare rather than in the last week. Compare cover for United Kingdom.

Australian demand for United Kingdom peaks in July, so the months either side of it are usually where the cheaper fares are.

Should I book my domestic connection to Sydney on the same ticket as my United Kingdom flight?
Yes, wherever you can. Canberra to Sydney is cancelled 5.3% of the time against a national average of 1.9%, and on one ticket a missed connection is the airline's to fix - they rebook you onto the next flight to United Kingdom. On separate tickets the international fare is your loss. If the legs have to be separate, fly into Sydney the night before.
