Return flights from London to Australia & NZ typically cost between £987 and £1274 in August, though fares move with demand, season and how early you book. The lowest fare our search found recently was £748 — a great price and well below the usual range, so a price near this is worth grabbing. Keeping your dates flexible and comparing nearby days is the easiest way to land at the cheaper end.
On average, November is the cheapest month to fly to Australia & NZ, with return fares around £932, and February is another good-value option at about £984. Prices peak in December, when return tickets average around £1610 because of higher demand. If your travel dates are flexible, shifting your trip into a cheaper month can save you a meaningful amount.
The cheapest day to depart to Australia & NZ is usually Thursday, when fares start from around £863 — midweek departures tend to be quieter and cheaper. Friday is typically the most expensive day to fly out (around £1110), as weekend travel is popular with leisure and business travellers alike. Where your plans allow, moving your outbound to a cheaper weekday can noticeably lower the total fare.
Flights to Australia & NZ are generally cheapest departing in the evening, with fares from around £816. Departures in midday tend to cost more (about £868), as those slots are more convenient and in higher demand. Picking an off-peak departure time is a simple way to trim the price without changing your dates.
The cheapest return flights to Australia & NZ depart from London Heathrow (LHR), from around £860. London has several airports serving this route and fares can vary between them — Stansted (STN) is often the priciest at around £1069. It's worth checking which London airport is both cheapest and most convenient for you before booking.
Yes — for Australia & NZ you can often save by taking a stopover: 1-stop fares start from around £809, compared with about £969 to fly direct. The trade-off is a longer total journey with a connection, so weigh the saving against the extra travel time. If budget matters more to you than speed, a 1-stop option is worth considering.
To get a below-average price to Australia & NZ, aim to book roughly 2 weeks before departure, when fares tend to dip to around £878. Leaving it to the final week is usually the most expensive time to buy, costing about 31% more, as availability tightens. Booking extremely far ahead isn't always cheaper either, so a few weeks to a couple of months out is typically the sweet spot.

Australia and New Zealand are among the UK's most sought-after long-haul destinations — a world of sun-drenched cities, stunning coastlines, outback adventure and dramatic scenery. Popular for holidays, visiting family and working travel, this corner of the world is reached by well-connected one-stop flights from the UK.
Seasons are reversed from the UK. December to February is summer Down Under — ideal for beaches — while our spring and autumn (their autumn and spring) offer mild weather and lower crowds. Fares peak around the festive season; the price charts on this page show the cheapest dates.
There are no non-stop flights from the UK, but excellent one-stop routes via a single hub. Qantas, Emirates, Qatar Airways, Singapore Airlines and Etihad connect London and other UK airports to Australia and New Zealand, typically via the Gulf or Asia. Total journey time is around 22–24 hours.
