Why Were Flight Prices to Australia Cheaper in 2025
Before you book, it helps to know how prices have moved. Domestic economy airfares in Australia were reportedly 12% cheaper in early 2025 than the year before, or about $29 off the average ticket, thanks to lower jet fuel costs and more seats on planes. That dip didn't last: jet fuel prices climbed sharply again in 2026, and Australia's domestic airlines have since raised fares and trimmed capacity on some routes to cover the extra cost. In practice, this means fares now swing more than usual from month to month, so the tips below matter more than ever for catching a good price when one appears.
When Is the Best Time to Book Cheap Flights to Australia?
- Book 8–11 months in advance for peak season (June–August, December).
- Travel in the Australian autumn/winter (April–June) for the lowest fares.
- Midweek flights (especially Wednesdays and Fridays) are often cheaper.
- Be flexible with your departure and return dates for the best deals.
Tips to Find the Cheapest Flights to Australia
Use these expert strategies:
- Compare prices across multiple sites: Check the same flight on a few sites before you book it.
- Set up fare alerts: Don’t rely on memory—let technology do the work!
- Be flexible with airports and dates: Sometimes flying into Melbourne instead of Sydney, or shifting your trip by a day or two, can save hundreds.
- Book return tickets: Round-trip flights are usually much cheaper than booking two one-way.
- Travel during off-peak months: Avoid December and January for the best rates.
- Check for last-minute deals: If your schedule is flexible, last-minute fares can be surprisingly low.
