If you are looking for cheap flights to Australia from the UK, the best time depends on whether your trip is to Sydney, Melbourne, Brisbane or Perth. Australia is a very seasonal long-haul market, so prices can swing with school holidays, summer beach travel and business demand.

February to March and May to June
December to January and UK school holidays
Why Australia Flight Prices Change
- Australia is a long-haul trip, so limited seat capacity can affect prices quickly on popular departure dates.
- December and January are especially busy because of festive travel and Australian summer holidays.
- UK school holidays, especially Easter and summer, can push fares up on family-friendly schedules.
- Weekend departures often cost more than midweek flights on the same route.
Pick the right Australian city first
Sydney and Melbourne are often the highest-volume routes, but Brisbane and Perth can offer better value on certain dates. If your holiday is flexible, compare all four gateways before you book.
Month-by-Month Snapshot
| Period | Fare Level | Best Action |

Do not leave Christmas Australia flights too late
Festive flights to Australia can move quickly because seats are limited and journey times are long. If your travel dates are fixed, early booking usually wins.
City-Specific Guidance
Australia fares vary by gateway. Sydney is the most searched city for UK travellers, Melbourne is popular for culture, sport and VFR travel, Brisbane often works well for Queensland holidays and Perth can be attractive for Western Australia and long-stay trips.
- Sydney: Best for first-time visitors, business travel and the widest route choice.
- Melbourne: Good for sport, events, family visits and city breaks.
- Brisbane: Useful for Queensland, the Gold Coast and family holidays.
- Perth: Great for Western Australia and travellers wanting a quieter gateway.
